Web“Gradient, divergence and curl”, commonly called “grad, div and curl”, refer to a very widely used family of differential operators and related notations that we'll get to shortly. We will later see that each has a “physical” significance. But even if they were only shorthand 1, they would be worth using. WebThe mathematical proof that curl = 0 at every point implies path independence of line integral (and thus line integral of 0 for all closed loops) is called Stokes' Theorem, and it is one of the great accomplishments of all mathematics.
