Out: ( WebOct 24, 2024 · The crucial fact about ∇ f is that, over a small displacement d l through space, the infinitesimal change in f is (1) d f = ∇ f ⋅ d l. In terms of the basis vectors in cylindrical coordinates, (2) d l = d r r ^ + r d θ θ ^ + d z z ^. Now, we are assuming that f is differentiable, i.e., it is locally linear. So
