1 + 1 = 2.

Is this an example you came up with?
I don't think a solution exists in terms of elementary functions.

Could we try this example instead?
f'(x)=2xcos(x^2+4)

Or was this a problem assigned from class?

Hmm ok this might be a little beyond my understanding then. :( Here is what the solution looks like: http://www.wolframalpha.com/input/?i=int+cos%28x%5E2%2B4%29 And here is some information on Fresnel Integrals (The big C and S in the solution): http://mathworld.wolfram.com/FresnelIntegrals.html What level of math class is this for? :o

it's for calculus 151
