okay i'm a little stumped on this problem

f(x,y) = integral {y to x} cos(t^2)dt

they want me to find Fx and Fy (partial differentiation)
i'm not sure how to integrate this and although I know the derivative of integrals is the function itself but it almost seems too easy to say that Fx = cos(x^2) any help/pointers? it would be greatly appreciated =]
