nambla (V dot U) = stuff

nambla is the del operator and "dot" is dot product...

I'm trying to figure out how to prove this seeing as I'm very rusty on my kronecker delta, levi-civita permutation tensor, and other vector calc related identities

any tips on the first couple steps?

the solution is on wikipedia if you google "vector calc identities" and it appears that it involves two partial derivative product rules or something

Anyway, I've been bored and stuck on what to do with this for a while tonight and can't figure out how to get the first few steps done that would very much refresh my brain ! many thanks to anyone who is willing to help
