Suppose that the several variable function z = ?(u, v, w) has continuous second order partial derivatives where u = f(v, w) and v = g(w). State appropriate versions of the chain rule for ?z/?w, (?z/?w)u, and (?z/?w)u,v.

Step 1
First, we need to find the partial derivative of z with respect to u, which can be written as: ∂z/∂u = ∂z/∂f * ∂f/∂u + ∂z/∂g * ∂g/∂u This is the chain rule for partial derivatives with respect to u. Show more…

Let $k$ be a constant, $\mathbf{F}=\mathbf{F}(x, y, z), \mathbf{G}=\mathbf{G}(x, y, z),$ and $\phi=\phi(x, y, z) .$ Prove the following identities, assuming that all derivatives involved exist and are continuous. $$ \operatorname{div}(\phi \mathbf{F})=\phi \operatorname{div} \mathbf{F}+\nabla \phi \cdot \mathbf{F} $$
