one to one function 2nd way

1. 1
   Take the function you want to check. For example, you might want to check f(x) = x-3 / x+2.
2. 2
   Plot the function on the x-y plane. Calculate some values for a few numbers, both positive and negative, using the function. Plot them on paper or using mathematics software. You will see an estimated shape of the function.
3. 3
   Draw a horizontal line on the graph. Make a horizontal line anywhere on the graph. This will allow you to perform the "horizontal line test."
4. Edit step
   4
   Determine whether the line intersects the graph of the function at more than one point. If the horizontal line intersects the graph at only one point, the function is one to one. If the horizontal line intersects the graph in more than one point, the function is not one to one.

one to one function

1

Take the function you want to check. For example, you might want to check f(t) = t-3/t+2.

1. 2
   Make functions f(x) and f(y) from f(t). To do this, change the variable t first to xand then to y. That way, you can perform the test with two different variables. So, in this example:
   

   • f(x) = x-3 / x+2
   • f(y) = y-3 / y+2
2. 3
   Set your two functions as equal. In this example, then: x-3 / x+2 = y-3 / y+2
3. 4
   Simplify the equation by cross multiplication. Cross multiplying the above equation results in an equation that looks like this: (x-3)(y+2) = (y-3)(x+2)
4. 5
   Simplify further by eliminating the parentheses. Multiplying the terms yields the following equation: yx+2x-3y-6 = yx-3x+2y-6
5. 6
   Continue simplifying. Keep simplifying as follows:
   

   • yx+2x-3y-6 = yx-3x+2y-6
   • 2x-3y = -3x+2y
   • 2x+3x = 2y+3y
   • 5x = 5y
   • x = y
6. 7
   Check whether x comes out equal to y. If so (like in the example above), the function is indeed one to one. If not, the function is not one to one.

FACTS ABOUT MARS

Right, we need to know about life

because May we can Life at MARS

• Mars is the fourth planet from the Sun and last of the terrestrial planets and is around 227,940,000 km from the Sun.
• The planet is named after Mars, the Roman god of war. It was known to the ancient Greeks as Ares, their god of war. This is thought to be because of the blood-red color of the planet which was also used by other ancient cultures. Chinese astronomers call Mars the “fire star” while ancient Egyptian priests called it “Her Desher” meaning “the red one”.
• The landmass of Mars and Earth is very similar.Despite Mars being just 15% the volume and 10% the mass of Earth, it actually has a similar landmass because water covers about 70% of Earth’s surface. The surface gravity of Mars is about 37% the gravity found on Earth. This means that on Mars you could in theory jump 3x higher than you could on Earth.
• Only 16 of the 39 Mars missions have been successful.Beginning with the USSR’s Marsnik 1 which was launched in 1960, 39 orbiters, landers and rovers have been to Mars but only 16 of those missions were a success. In 2016, Europe’s Exobiology on Mars program will search the planet for signs of Martian life as well as study the surface and terrain of the planet and map potential environmental hazards to future manned missions to Mars.
• Pieces of Mars have been found on Earth. It is believed that trace amounts of the Martian atmosphere were within meteorites that the planet ejected. These meteorites then orbited the solar system for millions of years amongst the other objects and solar debris before eventually entering the Earth’s atmosphere and crashing to the ground. The study of this material has allowed scientists to discover more about Mars before launching space missions.
• Mars was once believed to be home to intelligent life. This came from the discovery of lines or grooves in the surface called canali by Italian astronomer Giovanni Schiaparelli. He believed that these were not naturally occurring and were proof of intelligent life. However, these were later shown to be an optical illusion.
• The tallest mountain known in the solar system is on Mars. Olympus Mons is a 21 km high and 600 km diameter shield volcano that was formed billions of years ago. Scientists have found a lot of recent evidence of volcanic lava which suggests Olympus Mons may still be active. It is the second highest mountain in the entire solar system, topped only by the Rheasilvia central peak on the asteroid Vesta, which is 22 km high.
• Mars experiences huge dust storms – the largest in our solar system. This is due to the elliptical shape of the planet’s orbit path around the Sun. The orbit path is more elongated than many of the other planets and this oval shaped orbit results in fierce dust storms that cover the entire planet and can last for many months.
• The Sun looks about half its size half it does from Earth when seen from Mars. When Mars is closest to the Sun in its orbit the southern hemisphere points toward the Sun and this causes a very short but fiercely hot summer. In the north it experiences a brief but cold winter. When the planet is farthest from the Sun, Mars experiences a long and mild summer because the northern hemisphere points toward the Sun. This is compared with a cold and lengthy winter in the south.
• With the exception of Earth, Mars is the most hospitable to life – a number of space missions are planning for the next decade the further increase our understanding of Mars and when it has the potential for extraterrestrial life, as well as whether it may be a viable planet for a colony.
• Martians, also known as extraterrestrials from Mars, are a common character in science fiction books and movies. This makes Mars one of the most popular and talked about planets in the solar system.
• It takes Mars 687 Earth days to orbit the Sun with its orbit radius of 227,840,000 km.
• Mars is the only other planet besides Earth that has polar ice caps. The northern cap is called the Planum Boreum, with Planum Australe in the south. Water ice has also been found under the Martian ice caps.
• Mars has seasons like Earth, but they last twice as long. This is because Mars is tilted on its axis by about 25.19 degrees, which is similar to the axial tilt of the Earth (22.5 degrees).
• The orbit of Mars is the most eccentric of the eight planets. This means it is the least circular orbit path of the planets.
• The two moons of Mars, Phobos and Deimos, were written about in the book ‘Gulliver’s Travels’ by author Jonathan Swift – 151 years before they were discovered.
• Mars does not have a magnetic field – although there are some scientists that believe it did have a magnetic field somewhere around 4 billion years ago.

MORE INFORMATION AND FACTS ABOUT MARS

It was believed life existed on Mars for much of the nineteenth century. The reason behind this belief was part mistake and part imagination. In 1877, the astronomer Giovanni Schiaparelliobserved what he believed to be straight lines on Mars’ surface. As others noticed these lines, some suggested that they were too straight and could only be the work of intelligent life. The popular conclusion as to the nature of these lines was that they were canals constructed for irrigation purposes. However, with the development of more powerful telescopes in the early twentieth century, astronomers were able to view the Martian surface more clearly and determine that these straight lines were merely an optical illusion. As a result, the earlier claims of life on Mars were without evidence and, therefore, discarded.

The large amount of science fiction written during the twentieth century was a direct outgrowth of the belief that Mars possessed life. From little green men to death rays, Martians were the focus of many television and radio programs, comic books, movies, and novels.

Although the discovery of Martian life in the eighteenth century eventually proved to be false, Mars is nonetheless the planet most hospitable for life other than the Earth. As such, recent planetary missions have tried to determine if even the most basic of life exists on the planet’s surface. The Viking mission in the 1970s conducted experiments on the Martian soil in hopes of detecting microorganisms. While it was initially believed that the formation of compounds during the experiments were a result of biological agents, it has since been determined that these compounds can be created without biological mechanisms.

Even though the results lean toward the absence of life on Mars, scientists have speculated that conditions are right for life to exist beneath the planet’s surface. Future planetary missions scheduled to test the possibility of past and present life include the Mars Science Laboratory and ExoMars missions.

ATMOSPHERE

The composition of Mars’ atmosphere is extremely similar to Venus’, one of the least hospitable atmospheres in all of the Solar System. The main component in both atmospheres is carbon dioxide (95% for Mars, 97% for Venus), yet a runaway greenhouse effect has taken hold of Venus, producing temperatures in excess of 480° C, while temperatures on Mars never exceed 20° C. Thus, something other than the composition is at work. The huge difference lies in the density of the two atmospheres. Whereas Venus’ atmosphere is exceedingly thick, Mars’ is quite thin. Simply put, Mars would resemble Venus if it possessed a thicker atmosphere.

Additionally, with such a thin atmosphere, the resulting atmospheric pressure is only about 1% of that found at sea level on Earth. That is the equivalent pressure found at 35 km above the Earth’s surface.

One of the long standing areas of research regarding the Martian atmosphere is its impact on the presence of liquid water. What the research has shown is that even though the polar caps possess frozen water and the air contains water vapor&#8212as a result of the freezing temperatures and low pressure caused by the weak atmosphere&#8212it is not possible for liquid water to exist on the planet’s surface. However, evidence provided by planetary missions suggests liquid water does exist one meter below the planet’s surface.

Surprisingly, despite the thin atmosphere, Mars experiences weather patterns. The primary form of this weather consists of winds, with other manifestations that include dust storms, frost, and fog. As a result of this weather, some erosion has been seen to take place at particular locations on the planet’s surface.

As a final note on the Martian atmosphere, leading theories claim that it may have once been dense enough to support large oceans of water. However, through some means in the planet’s past the atmosphere was drastically altered. One popular explanation for this change is that Mars was struck by a large body and in the process a large portion of its atmosphere was ejected into space.

SURFACE

The surface of Mars can be separated into two broad features, which, coincidentally, are divided by the planet’s hemisphere. The northern hemisphere is seen to be relatively smooth with few craters, whereas the southern hemisphere is an area of highlands that are more heavily cratered than the northern plains. Other than topographical differences, the distinguishing feature of the two regions appears to be geological activity, with the northen plains being much more active.

The Martian surface is home to both the largest known volcano,Olympus Mons, and largest known canyon, Valles Marineris, in the Solar System. With a height of 25 km and a base diameter of 600 km, Olympus Mons is three times the height of Mt. Everest, the tallest mountain on the Earth. Valles Marineris is4,000 km long, 200 km wide, and almost 7 km deep. To put the shear magnitude of its size into perspective, Valles Marineris would stretch from the East to West coast of the United States.

Perhaps the most significant discovery regarding the Martian surface was the presence of channels. What is so meaningful about these channels is that they appear to have been created by running water, and thus providing evidence to support the theory that Mars could have been much more similar to the Earth at one time.

A surface feature that has remained in popular culture since its image surfaced is the “Face on Mars.” When this photograph was captured by the Viking I spacecraft in 1976, many took it to be proof that alien life existed on Mars. However, subsequent images showed that lighting (and a little imagination) are what brought life to the formation.

INTERIOR

Similar to the other terrestrial planets, Mars’ interior is divided into three layers: a crust, mantle, and core.

Although precise measurements cannot be made, scientists can make predictions as to the thickness of the planet’s crust based on the depth of Valles Marineris. Such a deep, extensive valley system, located in the southern hemisphere, could not be present unless the crust there is significantly thicker than the Earth’s. Estimates put its thickness in the northern hemisphere at35 km, and 80 km in the southern hemisphere.

Mercury’s core is believed to be approximately 3,000 km in diameter and composed primarily of iron. There is a significant amount of research being conducted to determine whether or not Mars’ core is solid. Some scientists point to the lack of a significant magnetic field as an indication that the core is solid. However, within the past decade much data has been gathered to indicate that the core is at least partially liquid. With the discovery of magnetized rocks on the planet’s surface, it appears, at the very least, that Mars did possess a liquid core at some point in its history.

ORBIT & ROTATION

The orbit of Mars is noteworthy for three reasons. First, its eccentricity is second largest among all the planets, smaller only than Mercury’s. As a result of this more elliptical orbit, Mars’ perihelion of 2.07 x 108 km is much larger than its aphelion of2.49 x 108 km. Second, evidence suggests that this high degree of eccentricity has not always been present, and it may have been less than the Earth’s at some point in Mars’ history. The cause for this change is attributed to the gravitational forces exerted upon Mars by neighboring planets. Third, of all the terrestrial planets, Mars is the only one having a year that lasts longer than the Earth’s. This, of course, is due to its orbital distance. One Martian year is equal to almost 686 Earth days.

It takes Mars about 24 hours 40 minutes to complete one full rotation, easily making the Martian day the closest in length to an Earth day.

At roughly 25°, Mars’ axial tilt is yet another similarity the planet shares with Earth. What this means is Mars actually experiences seasons like those on Earth, though each is substantially longer because of the orbital distance of Mars. Unlike the Earth, however, Mars’ two hemispheres experience quite different temepratures for each season. This is due to the much larger eccentricity of the planet’s orbit.

about Dota2

Dota 2 is a free-to-play multiplayer online battle arena (MOBA) video game developed and published by Valve Corporation. The game was released for Microsoft Windows, OS X, and Linux in July 2013 following a Windows-only public beta testing phase that began in 2011, and is the stand-alone sequel to Defense of the Ancients (DotA), a mod for Warcraft III: Reign of Chaos and its expansion pack, The Frozen Throne. Dota 2 is one of the most actively played games on Steam, with maximum peaks of over a million concurrent players.

Dota 2 is played in matches between two five-player teams, each of which occupies a stronghold in a corner of the playing field. A team wins by destroying the other side's "Ancient" building, located within the opposing stronghold. Each player controls one of 111 playable "Hero" characters that feature unique powers and styles of play. During a match, the player collects gold, items, and experience points for their Hero, while combating Heroes of the opposite team.

Development of Dota 2 began in 2009 when IceFrog, lead designer of the original DotA mod, was hired by Valve. Dota 2 was praised by critics for its gameplay, production quality, and faithfulness to its predecessor, despite being criticized for its steep learning curve.Dota 2 utilized the original Source engine until it was ported to Source 2 in September 2015, making it the first game to utilize the new engine.

Dota 2 has a widespread professional scene, with teams from across the world competing for prize money and glory in various competitive leagues and tournaments. The largest of the professional tournaments is known as The International, which is hosted by Valve and takes place annually at the KeyArena in Seattle, Washington. The 2015 edition of The International set a record for having the largest prize pool in eSports history, totaling over $18 million.

Bicycle Facts for Kids

Check out our fun bicycle facts for kids and enjoy learning about bikes and cycling history. Find information on different types of bicycles, brakes, pedals, tires, recreational cycling, professional cycling and much more. Read on for a wide range of interesting trivia and information related to bicycles.

Bicycles are human powered vehicles, typically featuring pedals, a seat, two wheels and a frame. There are over one billion bicycles found throughout the world. Bicycles are used for transport, recreation, competitive racing, courier delivery and a range of other tasks. Competitive cycling includes track cycling inside velodromes, time trials, mountain biking, BMX and longer events such as the Tour de France. The Tour de France was first held in 1903 and his since become the most famous cycling race in the world. Held over three weeks, the annually changing route goes through the Pyrenees and Alps before finishing in Paris. Tandem bicycles are made to be ridden by two or more people. Although unicycles (one wheel) and tricycles (three wheels) don’t have two wheels, they are sometimes still referred to as ‘bikes’. The energy required to cycle at low to medium speeds is roughly the same as the energy required to walk. Bicycles typically use a chain to transmit power to the rear wheel. To get efficient use of their pedaling, cyclists use a high gear when going downhill, a medium gear on flat surfaces and a low gear when going uphill. Different brake types include rim brakes, internal hub brakes and disc brakes. Some bicycles feature suspension. This is especially common in mountain bikes where they are used to help deal with the vibration caused by uneven surfaces. Road bikes typically have thinner tires inflated to higher pressures than those found on mountain bikes, taking advantage of the smoother surfaces that roads generally provide. Before the word ‘bicycle’ become popular (coming from the French word ‘bicyclette’), bikes were typically called ‘velocipedes’. Two wheeled transportation developed in the 1800s, from pushed powered bikes through to mechanical crank drives with pedals. You may have heard of the Penny-farthing, an early type of bicycle that featured a front wheel significantly larger than the rear. The name comes from the old British Penny and Farthing coins which represent the large and small wheels. The pneumatic tire came along in the later years of the 19th century along with the rear freewheel and coaster brakes. Cycling became increasing popular in the early stages of the 20th century as cycling clubs and races caught on.

Old Friend

You know, even if I am in a corner, dying (unless I am already dead!) I would write for my dear October. My old friend is here again and as always it has been a lovely and much awaited reunion. Unlike last year, this year I am walking a lot in October. Embracing every bit of it and that excites me immensely. I greet it in the mornings with its soothing mist and damp grass. I meet it in the afternoons with its not so-hot-and-not-so-cold but just-right, breeze. I hear it from the window during the nights with its orchestra of the swaying branches mixed in with a special melody by the crickets.

Life has been mostly good… and quiet. Quiet is good. Quiet is always good. Don’t ever not be grateful for the quiet, because chaos is always lurking beneath and it’s only just looking for an opportunity.

So yes, life has been good. My daily struggles involve changing bandages on my feet (because no matter what shoe I wear, it just wouldn’t become friends with my feet), and fighting with a spider. There is a spider that made her home outside my gate, by the mailbox, and she just wouldn’t leave. Her web looks ugly, and makes it seem as if I don’t care for my home.  So giving into my vanity, I have destroyed her home multiple times but she builds it right back up, sometimes within hours. Tough little gal. So there you have it, these days I have been losing to a tiny spider. Sigh.  I may have to call it a truce. I may just give it a name and see what happens. Like Charlotte… (or Aragog?). It looks like we are spending the winter together.

Sometimes we should. Sometimes we should stop fighting and let things run their course. Autumn teaches me that every year. Let go. You can’t stop the leaves from changing the colors, dying and disappearing, you can either enjoy the destructive beauty or you can fight it. You’ll fight it and you’ll lose. Because things have to run their course. And sometimes when we give into the stubbornness, we lose sight of what we are fighting for or fighting with.  For instance,  no matter how I look at it, my vanity is not more important than that poor spider’s life. But if I continue at it, soon it will become a matter of pride and I’ll lose sight of the fact that I am about to kill a living thing, for really no reason at all.

World's Largest Libraries

There are a number of institutions around the world that transcend the standard definition of library. From the U.S. Library of Congress to the Bibliotheque nationale de France, these bastions of words, sounds, images and ideas provide the intellectual foundation of modern society.

The American Library Association's list of the Nation's Largest Libraries outlines institutions with the most volumes, including the Library of Congress (30,011,748 volumes), Harvard University (15,555,533) and the Boston Public Library (15,458,022).

The Library of Congress in Washington D.C. turns 200 this year. Begun with fewer than 1,000 books, the library now holds 115 million items in a number of formats. "America's oldest national cultural center," the library is one of the largest repositories of recorded knowledge in the world. Established as a legislative library, it now serves as the copyright agency of the United States and the research arm of the U.S. Congress. With a staff of nearly 3,000 and an annual appropriation of more than $300 million, the library is truly a wondrous monument. Online, you'll find congressional records, committee information, legislative information and special exhibits.

The New York Public Library consists of 4 research centers and 85 branch libraries in Manhattan, Staten Island and the Bronx. With more materials than any other public library in the nation, it is the largest research library with a circulating system in the world. Established in 1895, the NYPL's collection has grown to more than 52 million items and serves millions of users.


The British Library is the United Kingdom's national library. Based in London and Yorkshire, it holds more than 62 million items, including prized manuscripts, rare maps and thousands of precious documents. Some documents are viewable online.

If you speak French, the Bibliotheque nationale de France's home page offers a number of services. For those confined to English, there is an alternate page with limited information.

IFLANET, the International Federation of Library Associations and Institutions, lists National Libraries of the World. To look up libraries by type and geographical location, try LibDex.

Phobias and Fears

Almost everyone has an irrational fear or two—of mice, for example, or your annual dental checkup. For most people, these fears are minor. But when fears become so severe that they cause tremendous anxiety and interfere with your normal life, they’re called phobias. The good news is that phobias can be managed and cured. Self-help strategies and therapy can help you overcome your fears and start living the life you want.

What is a phobia?

A phobia is an intense fear of something that, in reality, poses little or no actual danger. Common phobias and fears include closed-in places, heights, highway driving, flying insects, snakes, and needles. However, we can develop phobias of virtually anything. Most phobias develop in childhood, but they can also develop in adults.

If you have a phobia, you probably realize that your fear is unreasonable, yet you still can’t control your feelings. Just thinking about the feared object or situation may make you anxious. And when you’re actually exposed to the thing you fear, the terror is automatic and overwhelming.

The experience is so nerve-wracking that you may go to great lengths to avoid it—inconveniencing yourself or even changing your lifestyle. If you have claustrophobia, for example, you might turn down a lucrative job offer if you have to ride the elevator to get to the office. If you have a fear of heights, you might drive an extra 20 miles in order to avoid a tall bridge.

Understanding your phobia is the first step to overcoming it. It’s important to know that phobias are common. (Having a phobia doesn’t mean you’re crazy!) It also helps to know that phobias are highly treatable. You can overcome your anxiety and fear, no matter how out of control it feels.

Barbara’s fear of flying

Barbara is terrified of flying. Unfortunately, she has to travel a lot for work, and this traveling takes a terrible toll. For weeks before every trip, she has a knot in her stomach and a feeling of anxiety that won’t go away. On the day of the flight, she wakes up feeling like she’s going to throw up. Once she’s on the plane, her heart pounds, she feels lightheaded, and she starts to hyperventilate. It gets worse and worse with every flight.

Barbara’s fear of flying has gotten so bad that she finally told her boss she can only travel to places within driving distance. Her boss was not happy about this, and Barbara’s not sure what will happen at work. She’s afraid she’ll be demoted or lose her job altogether. But better that, she tells herself, than getting on a plane again.

Normal Fear vs Phobias

It is normal and even helpful to experience fear in dangerous situations. Fear is an adaptive human response. It serves a protective purpose, activating the automatic “fight-or-flight” response. With our bodies and minds alert and ready for action, we are able to respond quickly and protect ourselves.

But with phobias the threat is greatly exaggerated or nonexistent. For example, it is only natural to be afraid of a snarling Doberman, but it is irrational to be terrified of a friendly poodle on a leash, as you might be if you have a dog phobia.

The difference between normal fear and a phobia

Normal fear                                                                                                             

Feeling anxious when flying through turbulence or taking off during a storm

Experiencing butterflies when peering down from the top of a skyscraper or climbing a tall ladder

Getting nervous when you see a pit bull or a Rottweiler

Feeling a little queasy when getting a shot or when your blood is being drawn

Phobia

Not going to your best friend’s island wedding because you’d have to fly there

Turning down a great job because it’s on the 10th floor of the office building

Steering clear of the park because you might see a dog

Avoiding necessary medical treatments or doctor’s checkups because you’re terrified of needles

Arc Warden is released

Valve’s DotA 2 has a ton of heroes that gamers can choose from, but if for some reason none of them have really appealed to you, you might be interested to learn that Valve has recently announced last update of the game in the form of version 6.86 which they are calling “The Balance of Power” update.

Possibly the most notable change with the update is the addition of a new hero in the form of the Arc Warden (which was one of the heroes from the original DotA). According to the description of the hero,“Assault lone enemies with fluxing energy, or distort space to generate a protective field around allies. Summon a Spark Wraith to patrol an area for enemies to infuse with harmful magic, then create a double of Zet, items and all, to overwhelm your foes.”

The hero comes with abilities such as Flux, Magnetic Field, Spark Wraith, and Tempest Double as its ultimate. The update will also introduce an Arcana item in the form of Tempest Helm of the Thundergod for the Zeus hero. There is also the inclusion of the desert terrain as promised to owners of The International 2015 Compendium, a music pack, improved shadow quality, and more.

As expected the update will also bring about bug fixes, balancing, tweaks and changes to the DotA 2 client, and more. So if you’d like to see the rest of the changes that Valve has made in version 6.86 of the game, head on over the website for the details.
