WebJan 17, 2015 · 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 … WebCurl. The second operation on a vector field that we examine is the curl, which measures the extent of rotation of the field about a point. Suppose that F represents the velocity field of a fluid. Then, the curl of F at point P is a vector that measures the tendency of particles near P to rotate about the axis that points in the direction of this vector. . The …
