Q: Solve on white page clean and stepwise: Let f(x, y, z) = sinxyz, g(x, y, z) = x²yz, U = x²yi – y²zj + 2xz²k and V = xi – 2zk. Then verify the following relations 1. div(fU) = fdiv(U) + U · Vf 2. div(gradf) = 7?f 3. div(fVg) = fV²g+Vf•Vg 4. div(U × V) = V· curlU – U · curlV 5. curl(curlU) = grad(divU) – V²U
