(1 point) Let [math] be a vector field in the plane, and [math] the path [math] joining (0,0) to (1,5) in the plane. A. Evaluate [math] B. Does the integral in part (A) depend on the path joining (0,0) to (1,5)? (y) (1 point) Consider the vector field F(ac, y, z) 2 (9y, 9m, 6z). Show that F is a gradient vector field F 2 VV by determining the function V which satisfies V(0, 0, 0) = 0. V(ac, y, z) =
