5 a) Use an integral theorem to evaluate lls curl(F) ·dS, where F(x, y, z) = (x2yz, yz2,23ery), where is the part of upwards on- ented surface x2 + y2 + 22-5 that lies above the plane z = 1. b) Use an integral theorem to compute the line integral of F(x, y, z) = 2:3,3/5, 22) along the path t)-(cos(t) + t100 sin(17t), sin(t) + sin(20t),t) frorn t = 0 to t = 10ml
