Yes i am. I think i got the answer. I believe the appropriate rule is: \nabla \cdot \vec{μ} f = \nabla f \cdot \vec{μ} + f \nabla \cdot \vec{μ} You need to start with \nabla \cdot f\nabla f = \nabla f \cdot \nabla f + f(\nabla \cdot \nabla f) which becomes: \nabla...

Apparently, f \nabla^2 f = \nabla \cdot f \nabla f - \nabla f \cdot \nabla f where f is a scalar function. Can someone please show me why this is step by step. Feel free to use suffix notation. Thanks in advance.
