Verify Green's Theorem in the plane for [(x2 -- xy3)dx +(y2 - 2xy)dy], where C is a rectangle with vertices at (1, 2), (1, -2), (1, 1) and (1, 1).
[Hint: start by separating the integral into four parts, one for each side of the
rectangle, and writing down an expression for y in terms of x for each part - you
