WebIf a vector field is the gradient of a scalar function then the curl of that vector field is zero. ... Nor does this follow from the gradient theorem. Nor is the proof found on the cited wikipedia article (at the time of writing). $\endgroup$ – Aerinmund Fagelson. Jul 7, 2024 at 16:28. Add a comment

WebJun 16, 2014 · Add a comment 4 Answers Sorted by: 50 +100 You only need two things to prove this. First, the BAC-CAB rule: A × ( B × C) = B ( A ⋅ C) − C ( A ⋅ B) And the product rule. Let ∇ ˙ × ( F ˙ × G) mean "differentiate F only; pretend G is constant here". So the product rule would read ∇ × ( F × G) = ∇ ˙ × ( F ˙ × G) + ∇ ˙ × ( F × G ˙) Webthe gradient of a scalar field, the divergence of a vector field, and the curl of a vector field. There are two points to get over about each: The mechanics of taking the grad, div or curl, for which you will need to brush up your multivariate calculus. The underlying physical meaning — that is, why they are worth bothering about. 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.
