Homework Statement
For arbitrary vector fields A and B show that:
∇.(A ∧ B) = B.(∇∧A) - A.(∇∧B)
The Attempt at a Solution
I considered only the 'i'-axis, by saying that it is perpendicular with A and B and then I expanded both the left and right side out. The working is too much to post here..I didn't manage to prove it. I was hoping someone would know if there's a useful webpage where I can find out more about vector calculus identities.
Thanks!
