WebI'm stuck on the notation of the 2d curl formula. It takes the partial derivatives of the vector field into account. I believe it says the "partial derivative of the field with respect to x minus the partial derivative of the field with respect to y", but I'm not certain. Since I'm using … 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.

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

"Web\] Since the $x$- and $y$-coordinates are both $0$, the curl of a two-dimensional vector field always points in the $z$-direction. We can think of it as a scalar, then, measuring how much the vector field rotates around a point. Suppose we have a two-dimensional vector field representing the flow of water on the surface of a lake. " - Curl of a vector field equation
