Would I be right in assuming that the chain rule and quotient rule also still apply?

Oh well, this is one way to learn tex. \nabla = {\partial \over \partial x}\mathbf{\hat{i}} + {\partial \over \partial y}\mathbf{\hat{j}} + {\partial \over \partial z}\mathbf{\hat{k}} A = A_1\mathbf{\hat{i}} + A_2\mathbf{\hat{j}} + A_3\mathbf{\hat{k}} LHS = \nabla \cdot (\psi\mathbf{A})...

Homework Statement I am trying to prove that: \nabla \cdot (\psi\mathbf{A}) = \mathbf{A} \cdot\nabla\psi + \psi\nabla \cdot \mathbf{A} Where nabla is a scalar function and A is a vector field The Attempt at a Solution I tried expanding both the LHS and RHS, but I think I am getting...
