Can anyone help me with the integral of cos(y^2)?
Possibly. Can you reduce cos(y^2) down and express it in terms of sin(y) and cos(y)?
not really. I'm finding functions, given the gradient...
((e^x)*cos(y^2))i - (2y(e^x)sin(y^2))j
I reckon you can. How about if you write cos(2y)=cos(y+y)=...
cristo - its cos (y^2), not 2y :(
caaron3 - it has no elementary solution, though if you really want some sort of a solution, the anti derivative is in terms of the Cosine Fresnel Integral, so look that up.
