Alright, I'll start it for you, but you have to finish it yourself.
Basically we have f(x^2). Now, if we were to diffentiate F(x^2), we'd end up with 2xf(x^2), so, what do we do to get rid of that 2x?

Go for it. Integration by parts

You can try using this useful online integrator: http://integrals.wolfram.com/index.jsp
When I tried inputing your expression inside, I got
Sqrt[Pi/2] * FresnelS[Sqrt[2/Pi] * x]
Although I'm clueless on what that means, I hope this helps.

i will rty to do integratin by parts as several say to to that
( btw how old are you ? )
( sin(x^2) ) ' = cos(x^2) *d x^2 = cos(x^2) *2x dx
so Int (sinx^2) dx = x(sinx^2) - Int ( x.(cos(x^2) *2x ) dx )
etc etc etc etc until you have a Int(sometingwith x * sin(x^2))dx
then you an write the Int explicit and you are done

use integration by parts.

You cannot solve this problem in closed form.
