how do you integrate sin(x^2)? ive been searching the book and google...cant find a way to do it, so im thinking its not possible. obviously sin^2(x) is easy, so dont confuse it with that.

this is a tiny part of a huge problem, and i havent done this since last spring so i cant remember wtf to do. it should be calc I and im in calc III lol...

It does (by the fundamental theorem of calculus), but it can't be expressed in terms of elementary functions.

Right you are. I should have worded it more robustly.
