- ## ∇ ⋅ (fg) = ∇f ⋅g + f(∇ ⋅ g) ##

I don't understand why ?

## \Psi ∇ ⋅ (A \Psi^ *) + \Psi ^* ∇ ⋅ (A \Psi ) = 2 ∇ ⋅(A \Psi ^* \Psi) ##

form

## ∇ ⋅ (fg) = ∇f ⋅ g + f(∇ ⋅ g) ##

Attempt at a Solution

## \Psi ∇ ⋅ (A \Psi^ *) + \Psi ^* ∇ ⋅ (A \Psi ) = 2 ∇ ⋅ (A \Psi ^* \Psi) - ∇\Psi ^* ⋅ A\Psi - ∇\Psi ⋅ (A\Psi ^*) ##
