Homework Statement
Find the partial derivatives:
f(x,y)= integral[x,y] cos(t^2)dt, find f_x(x,y) and f_y(x,y)
Homework Equations
I know from calculus that the derivative of an integral is the function.
The Attempt at a Solution
I found that the integral of [x to y] cos(t^2)dt=sin(t^2)= sin(y^2)-sin(x^2)
and then found the partial derivative of this.
fx=-2xcos(x^2)
fy=2ycos(y^2)
I have seen other procedures and I think I'm wrong. Could someone help?
