1. The problem statement, all variables and given/known data I have to solve the integral of (ytan^-1(x) - 3) inside the area of the rectangle with vertices (1,0), (0,1), (2,3), (3,2). How do I set up these limits? 2. Relevant equations This is a tilted rectangle so I can't use just values for the limits? 3. The attempt at a solution This is a Green's theorem problem that started out as integral(tan^-1(x)dx + 3xdy). I just can't figure out the limits.
