Use Green's theorem to evaluate the line integral along the given positively oriented curve. cos(y) dx + x2 sin(y) dy, C is the rectangle with vertices (0, 0), (4, 0), (4, 2), (0, 2) DETAILS SCALCET9 16.XP.4.009. MY NOTES ASK Y Use Green's theorem to evaluate F. dr. (Check the orientation of the curve before applying the theorem.) F(x, y) = (y cos(x), x + 2y sin(x)), C is the triangle from (0, 0) to (3, 9) to (3, 0) to (0, 0)
