Curl of a gradient proof

Webgradient A is a vector function that can be thou ght of as a velocity field of a fluid. At each point it assigns a vector that represents the velocity of ... The curl of a vector field at a point is a vector that points in the direction of the axis of rotation and has magnitude represents the speed of the rotation. ( ) ( ) ( ) Vector Field 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).
