It is very much parallel to the theory of gradient (= conservative) vector fields. However, we considered it in less detail. shrinkage traduction

"WebTheorem 16.5.1 ∇ ⋅ (∇ × F) = 0 . In words, this says that the divergence of the curl is zero. Theorem 16.5.2 ∇ × (∇f) = 0 . That is, the curl of a gradient is the zero vector. Recalling that gradients are conservative vector fields, this says that the curl of a conservative vector field is the zero vector. " - Curl of a vector field equation

WebSep 7, 2024 · Equation shows that flux integrals of curl vector fields are surface independent in the same way that line integrals of gradient fields are path independent. Recall that if is a two-dimensional conservative vector field defined on a simply connected domain, is a potential function for , and is a curve in the domain of , then WebThe idea is that when the curl is 0 everywhere, the line integral of the vector field is equal to 0 around any closed loop. Thus, if the vector field is a field of force (gravitational or electric, usually), then the line integral along any path gives us the total work done by the force.
