(2 points) The figure below open cylindrical can, S, standing on the cy-plane. (S has a bottom and sides, but no top.) 21 X The side of S is given by x2 + y = 1, and its height is 3. (a) Give a parametric equation, r (t) for the rim, C. T ( t ) = , With (For this problem, enter your vector equation with angle-bracket notation: ) (b) If S is oriented outward and downward, find J- curl (-6yi + 6xj + 52k) . dA. Is curl (-6yi + 6xj + 5zk) . dA =
