Hello! Please help me out with this calculus 3 problem. I just want to see a step by step on how to solve it ON PAPER. No need to explain each step in words. Solve them problem so I can understand. Thanks!

(2) Use Stoke's theorem to evaluate the integral curl F . ds where S is the surface given by (3) 2 =4- x2 - y2, z 2 0, oriented upwards and F (x, y, z) = yi + zex /yj- cos (x2) ey arctan zk vote: to get full credit for this problem, do NOT compute curl F . To get full credit, you must , Stoke's theorem to solve the problem.)
