WebProofs [ edit] For ( 1 ), both sides are antisymmetric with respect of ij and mn. We therefore only need to consider the case i ≠ j and m ≠ n. By substitution, we see that the equation holds for ε12ε12, that is, for i = m = 1 and j = n = 2. (Both sides are then one). WebThe curl of a vector field ⇀ F(x, y, z) is the vector field curl ⇀ F = ⇀ ∇ × ⇀ F = (∂F3 ∂y − ∂F2 ∂z)^ ıı − (∂F3 ∂x − ∂F1 ∂z)^ ȷȷ + (∂F2 ∂x − ∂F1 ∂y)ˆk Note that the input, ⇀ F, for the curl is a vector-valued function, and the output, ⇀ ∇ × ⇀ F, is a again a vector-valued function. how to create an online form to fill out

http://mathonline.wikidot.com/curl-identities WebMay 9, 2012 · A well known vector identity is that rot (rot (E)) = grad (div (E)) - div (grad (E)). I've actually used this before without encountering any problems, so I don't know if I'm just having a brain fart or something, but shouldn't grad (div (E)) be equal to a vector and div (grad (E)) be equal to a scalar? How can you add or subtract them?
