O NO!

my calculus class is going to eat me alive. i just spent an hour on 10 problems, and still don't understand them all. i got 9/10 though :) the other one was a fucking trick question... dammit...

it was a fraction with x being on the bottom... then said f(x) = 0. X CANNOT BE 0!!! but whatever, the answer was apparently 1/36 or something. wahhhh.
