Use Green's theorem to evaluate the following integrals: 2a dy - 3y da around the square with vertices (0, 2), (2,0), (-2,0), and (0, -2). fayda + a dy, where C is as sketched. VVT X 0 4 $(2y dx - 3x dy) around the square bounded by x = 3, x= 5, y = 1 and y = 3. Je(rsinx - y) dx + (x - y2) dy, where C is the triangle in the (x,y) plane with vertices (0,0), (1, 1), and (2,0). Jyr) dx + (2xy + 3) dy along the ar axis from (0,0) to (5,0) and then along a circular are from (5,0) to (1,2).
