Anyone else go through a brief panic during a math test only to use your mathematical knowledge to figure shit out? Share your stories! Tongue

It's only a debate if both parties are willing to let each other's opinions change their own.
If you aren't willing to change in light of learning more about what you fight for, what the hell are you doing expecting the other party to want to change?

There are a formulas (arc length and sector area, for example) that I never actually learned, but instead I just figured out how to do it myself. If the angle is 36 degrees it's 1/10th of the circle and thus the arc is 1/10th of its circumference and the sector 1/10th of its area. There have been times when I've forgotten the derivatives of secant, cosecant or cotangent and so I've managed to figure them out by putting them in terms of sine or cosine. Once for Quiz Bowl I completely made up a formula and used it for a problem and got it right (I can't remember the problem now unfortunately).

*scratches head*
dafuq is this dude talking about?

i'm really bad as soon as soon as you include z coordinates and 3d objects,and pretty much nothing can help me during such a test

KC IS A LIAR!!!! HE PROMISED ME VANILLA CAKES AND GAVE ME STRAWBERRY CAKE Weeping
