WebNov 16, 2024 · Curl and Divergence – In this section we will introduce the concepts of the curl and the divergence of a vector field. We will also give two vector forms of Green’s Theorem and show how the curl can be used to identify if a three dimensional vector field is conservative field or not. WebAs H, G have the same curl, it follows merely that (G − H) is the gradient of some function. On that note, if you have a curl-free field W = (W1, W2, W3), it is the gradient of a function f given by f(x, y, z) = ∫1 0 (xW1(tx, ty, tz) + yW2(tx, ty, tz) + zW3(tx, ty, tz))dt.
