WebIf we arrange div, grad, curl as indicated below, then following any two successive arrows yields 0 (or 0 ). functions → grad vector fields → curl vector fields → div functions. The remaining three compositions are also interesting, and they are not always zero. For a C 2 function f: R n → R, the Laplacian of f is div ( grad f) = ∑ j = 1 n ∂ j j f WebThis is exactly the formula we gave above. So if you can use the rule that “multiplication” by ∂ ∂ x is the same as taking the partial derivative with respect to x (and similar for the other derivatives), then you can remember the curl formula by curl F = ∇ × F. truscott toyota croydon
