Homework Statement
Evaluate the double integral sin(x-y)*e(x-y)^2-0y) 2--- dA where D is a disk of radius 2 whose center is (1; 1)
Homework Equations
The Attempt at a Solution
gee this problem stumped me. I've been working on it for over 3hrs. I've tried changing into polar form and integrating that. That just takes me to an even messier integral. My professor says their is a trick, but I can't find it. I have a hunch somehow the integral will come down to finding the area of the disk, but I'm not sure how to get to that point.
Just to prove I've tried something: sin(r(cos(theta)-sin(theta)))*e^(r^2(cos(theta)-sin(theta)))*r
that is what my integrand would be if I change it to polar
Please help me. I am so frustrated.
