1. ## Vector Calculus Operators

Okay, I have an exam on vector calculus tomorrow, and theres is one simple thing I just can't find anything about in my notes.

With the gradient, divergence and curl formulas, there are a couple of similar ones in my questions.

I know (F . Del)f [ F = vector field, Del = operator f = scalar field]

But could somebody please tell me how to find

(F . Del)F

???

Thank you

$\displaystyle (F . \nabla)F$ is a psuedo-vector expression. If $\displaystyle F=<u,v>$ then $\displaystyle (F . \nabla)F = <u u_x + v u_y, u v_x + v v_y>$

dearest rossleeds.
It is indeed an interesting question you ask there and i believe i have a solution

is a psuedo-vector expression. If then

hope this helps
