Calculus in 3D Section 3.3: Vector identities (involving nabla/del operator)

00:00 - Explaining the possibilities of how to operate with the del operator on products of scalar and vector functions
02:30 - The vector identities you should be aware of (you don't need to memorise!)
02:50 - An example showing how to prove a vector identity
08:05 - Higher order derivatives, i.e., involving more than one del operator: the Laplacian, "curl grad f" "div curl A" and "curl curl A"
