Remember in Trigonometry, when you learned that if you take the sine of 235 degrees, the 235 can actually be changed to 55? Remember how your teacher (hopefully, you had a somewhat coherent one) explained exactly why this was so, using graphs and visual aids and all that other good stuff that math teachers have to use? Remember how they always explained why everything was as it was, even if it took all class period and the majority of the class could be pronounced legally dead of boredom by a certified coroner? Don't you remember that?

Well, we're going to skip the scary sine-thing and move right on to the actual point of the essay -- pi! Well, after the scary sine-thing, you should have learned that in order to convert the number of degrees in a circle to radians, one must multiply it by pi divided by 180. However (you may have falled asleep during this part) the math teacher never explained why! "It'll take too long," she said, while you all looked at each other with rais-ed eyebrows, clearly signing out in Secret Eyebrow Code: "HUH?"

What do we do? Do we take the word of our possibly incorrect math teacher on the matter of pi over 180? Let me put this into perspective.

Okay, let's say that you don't believe your math teacher. You take the next test, flunk, and your parents get angry. In your teenage spirit of rebellion, you refuse to believe anything else your math teacher tells you. Therefore, you flunk the final exam. Your rebelliousness spreads to other classes, therefore preventing you from getting into an Ivy League college. Your parents, in shame, disown you, and you end up on the streets, your life in ruins. And all because of pi.

Therefore, it is absolutely necessary that you just believe in pi over 180. Call it a leap of faith, if you will. It's like believing in free will -- your disbelief will ultimately remove you from society and the gene pool. And all because of pi.
