scratch that last post, it was dumb.
Well I started by taking the left side of the equation and get to this:
[d/dy(us-rv)+d/dz(ut-rw)]i-[d/dx(us-vr)-d/dz(vt-ws)]j+[d/dx(ut-wr)-d/dy(vt-ws)]k
if I add d/dx(ur-ru) to the i component, d/dy(uv-vu) to the j component and d/dz(uw-wu) to the k...
Homework Statement
I need to prove curl(A x B) = AdivB - BdivA + (B·∇)A - (A·∇)B
But I keep on getting confused in the numbers. I tried taking the cross product A x B and crossing that into the gradient, but I just get lost. I also tried going from the right side of the equation and get lost in...
