Are you sure you've got that formula right? That's a very difficult integral to do (I'm not even sure it's possible to do without a computer).
Edit: to the poster above me, It's possible to do using wolfram: manipulate the integral then use wolfram to integrate cos (x^2), which gives you a result in terms of the Fresnel Integral, or just put numbers in instead of a and b and wolfram stops being confused e.g. http://www.wolframalpha.com/input/?i...8x-3%29%5E2%29
But yeah, I'm expecting a typo in the OP

Pic from mathcad attached, hope this helps.
You need to put the plus C in yourself, I know, useless isn't it
And unless I am missing something wolfram gives the same
int cos(a*(t-b)^2) w.r.t t = copy and paste and see.
