Formula for curl of a vector field

WebJan 17, 2015 · 1. A tricky way is to use Grassmann identity a × (b × c) = (a ⋅ c)b − (a ⋅ b)c = b(a ⋅ c) − (a ⋅ b)c but it's not a proof, just a way to remember it ! And thus, if you set a = b = ∇ and c = A, you'll get the result. – idm. Jan 17, 2015 at 17:58. @idm Yes, I saw that, and I agree with you, it's not really a proof. WebThis straight-line path is parametrized by (x, y, t), t moves from c to z. Let Cp, q be the piecewise linear curve obtained in this way. Then ∫Cp, qG ⋅ dx = ∫x aG1(t, b, c)dt + ∫y bG2(x, t, c)dt + ∫z cG3(x, y, t)dt. So one way to …
