Thanks in advance

1. Calculate a. curl(F) . ds where F(x, y, z) = (5y, 3x, 2z) and E is the top half of the unit sphere with upward orientation. (er + y', y' cosy + 4x, 24 + y?) . dr b. where C is the trajectory that moves along straight lines starting from (1, 0, 0), then to (0, 0, 1), then to (0, 1, 0), and then back to (1, 0, 0). (y'z, e' sin? z + 2y, are' + z) . ds C. where S is the sphere (x - 3)2 + (y + 3)2 + (2 - 1)2 = 16 oriented positively (outward- pointing normal)
