In mathematics, the trigonometric functions (also called the circular functions) are functions of an angle. They relate the angles of a triangle to the lengths of its sides. The most familiar trigonometric functions are the sine, cosine, and tangent ($\sin\left ( x \right )$, $\cos\left ( x \right )$, and $\tan\left ( x \right )$). If you took trigonometry in high school, you also might know about secant, cosecant, and cotangent ($\sec\left ( x \right )$, $\csc\left ( x \right )$, and $\cot\left ( x \right )$). But what about Exsecant ($eccsc\left ( x \right )$) or coversed sine ($cvs\left ( x \right )$)? So today, we are going introduce to you the other trigonometric functions!
More info will be coming soon about these other trigonometric functions. Think of it as a Calculus Humor miniseries!
We have redone our forum! We have revamped it and have made it better than ever! Plus side, it works (which was the downfall of our old forum) Come check it out at http://forum.calculushumor.com!
(CBS News) Take an unpopular academic subject, a dedicated visionary, and $23 million, and what have you got? Why, it all adds up to the museum our Mo Rocca's about to guide us through: Math. The very word conjures painful memories: long division . . . Square roots . . . The quadratic equation. Not only do most of us not like it; we're also not very good at it. In an international test of 15yearolds, the U.S. placed 24th out of 64 countries. "We don't currently, in this country, have a cultural expectation that yeah, you're going to learn math just like you're going to learn reading," said Glen Whitney. "It's okay to not be good at math." Glen Whitney is good at math. He's got a Ph.D in it, and is trying to change the way we think about one of our least favorite subjects. "I loved math. I loved algebra. I really loved geometry, [but] I hit the wall at precal," said Rocca. "That's the problem," said Whitney, "because you were only given one road to go through mathematics. You got the impression that once you hit the wall, that's it. There's nothing more for you. In fact, math is this extremely, very beautiful landscape. And we're showing people just one road cut right through the center of it." Whitney says our math curriculum is designed for rocket scientists. Literally! Fifty years ago America was in a space race against the Soviet Union, and beefing up on our math program was seen as a winning solution. Whitney said America was on a mission then: "We had to, you know, beat the Soviets to the moon. So we needed, you know, the young, bright science or math kid to be our hero to take us to the moon. And we haven't had a mission like that since then to capture the public imagination as to the importance of math." That's where Whitney and his latest project come in  a museum devoted entirely to math. "With our opening, there's now one math museum in North America," he told Rocca. "That's not a difficult math problem," Rocca replied. The Museum of Mathematics (MoMath for short) opened in December in New York City. With $23 million behind it, it feels less like a classroom and more like a playground. Museum cofounder Cindy Lawrence showed Mo around. There was a squarewheeled tricycle that somehow rides like a dream. "It's smoother than a Lexus," Rocca laughed.(CBS News) Take an unpopular academic subject, a dedicated visionary, and $23 million, and what have you got?

"Every sphere we touch, you're hearing three notes  a triad, a chord," Lawrence said. "There's something sinister, eerie about it. Minor keys are always kind of evil, right?" You can get your freak on with fractals. And what are fractals? "A fractal is a pattern of repetition where the same image is repeated over and over again, but in even smaller sizes," said Lawrence. And only here could you call a bathroom, a mathroom, with pentagonal sinks that go down to a triangular base. The message is simple: math is everywhere; a part of our daily lives, from the time you get out of bed ("Timekeeping was one of the original drivers for the creation of mathematics," said Whitney), to putting on your glasses ("Optics has its foundation in mathematics"), to knotting your bow tie ("I see your bow tie. And the knot there is one of the most vibrant, rich areas of mathematics right now"). And that's the point  math may not be as easy as pi, but it isn't so square, either. "Do you think that math lovers can seduce the math haters into liking math?" aske dRocca. "People who are really engaged with math understand that there's a lot of folks out there that don't see it the same way they do," said Whitney. "And they really want to show them the beauty and the wonder and the excitement that they experience. So hopefully, we've done that. Time will tell. But that's certainly what we're trying to do." We just redid our forum. We are sorry about things that got lost. We were finding too many issues with it that we decided to start from scratch. Please visit http://forum.calculushumor.com to see our new forum.
Sorry for any issues. In the next several weeks, Calculus Humor's website will be going to go through a redesign. We will try to make the redesign as painless as possible, but if you find a broken link or something worst, please send us an email to [email protected].
