## Homework Statement

I am trying to prove that:

[tex] \nabla \cdot (\psi\mathbf{A}) = \mathbf{A} \cdot\nabla\psi + \psi\nabla \cdot \mathbf{A} [/tex]

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 confused with the order of operations or something.
