    Well, First, I think that you don't understood what I say, because i don't speak english, so its hard but I try to post, others understood me and have answered my question. In fact you don't understood nothing. Second, It is a general question, and don't a homework question, my homework I...

    What is the purpose of using the nabla operator in this equation?

    A simple question: In a homework I find : F1 X nabla X F2 where X is the simbol of cross product I know that AX(BXC)= (A*C)*B-(A*B)C Where* here is used to divergence In the next step it was: -Nabla*(F2)F1 + nabla(F1*F2) I don't understant it, why?
