1. The problem statement, all variables and given/known data

2. Relevant equations

none

3. The attempt at a solution

So i reversed the order...

and couldn't figure out how to integrate cos(8x^2). I looked at my trig identities, tried on my graphing calc, and even wolfram alpha gave me a strange answer that i cant use.

Either i'm doing something wrong, or missing something obvious.

Thanks

Jake
