WebJul 23, 2004 · another way to look at it is via the basic theorems using these terms, i.e. green's theorem, gauss's theorem, and the divergence theorem. e.g. if you look at greens thm i believe it says that the integral of Adx + Bdy around a closed path, equals the integral of the curl of (A,B) over the inside of the path. WebJan 3, 2024 · 576 2 8 3 Not sure why you need all this machinery: Curl [Grad [f [x, y, z], {x, y, z}], {x, y, z}] returns {0, 0, 0} directly. You can also apply pdConv to the intermediate result of Grad, but I would not do computation of the results of *Form functions, as those are output wrappers only ("pretty-printers"). – MarcoB Jan 3, 2024 at 19:51
