Identity 3: DIV(f G)=f [DIV(F)] + F [Gradient(f)]
Example: Divergence of a product
Gradient of f
Take the divergence of the vector field
Multiply scalar function with derivatives of vector field
Adding terms
Verify Identity 3
It is nabla or del. "del f" is how you would pronounce the gradient of f. (or grad f). nabla is an upside-down Greek delta.
