# Math Help - Vector cross product, del show that and divergence theorem

1. ## Vector cross product, del show that and divergence theorem

Okay, this is what I got:

even if you try to work backwards surely if you do matrix 1 - matrix 2 you get zero for the middle row of the resulting matrix?

2. ## Re: Vector cross product, del show that and divergence theorem

part one looks to just be careful bookkeeping
