WebMar 14, 2024 · Yes, the product rule as you have written it applies to gradients. This is easy to see by evaluating ∇ ( f g) in a Cartesian system, where. (3) ∇ ( f g) = g ∇ f + f ∇ g. Yes you can. Gradient is a vector of derivatives with respect to each component of vector x, and for each the product is simply differentiated as usual. WebFeb 23, 2024 · The quickest proof is to just use the definition of divergence, curl and gradient, plug everything in and check that terms miraculously cancel out to give you $0$ (essentially it's because for sufficiently nicely behaved functions, the order of partial derivatives does not matter; this is called Schwarz's theorem in multivariable calculus).
