Find fx, fy, and fz.f(x ,y, z) = sin (xy) cos (yz2)
A. fx = y cos (xy) cos (yz2); fy = z2 sin (xy) sin (yz2)- x cos (xy) cos (yz2); fz = 2yz sin (xy) sin (yz2) B. fx = y cos (xy) cos (yz2); fy = x cos (xy) cos (yz2) - z2 sin (xy) sin (yz2); fz = -2yz sin (xy) sin (yz2) C. fx = y cos (xy) cos (yz2); fy = x cos (xy) cos (yz2) - z2 sin (xy) sin (yz2); fz = 2yz sin (xy) sin (yz2) D. fx = y cos (xy) cos (yz2); fy = x cos (xy) cos (yz2); fz = -2yz sin (xy) sin (yz2)
Solve the problem.The base of the closed cubelike surface is the unit square in the xy-plane. The four sides lie in the planes , x = 1, y = 0, and y = 1. The top is an arbitrary smooth surface whose identity is unknown. Let
