# Math Help - Quick Vector Field question

1. ## Quick Vector Field question

Find the divergence of $F(x,y,z) = <0, e^{xy}cosz,ytan^{-1}(\frac{x}{z})>$.

$xe^{xy}cosz-\frac{yx}{z^2+x^2}$ which was marked wrong, would someone be able to point out what I need to fix? Thanks a lot!

I don't see a problem with it.

3. Concur with Danny, although, as a matter of notation, I prefer parentheses around all function arguments, to make everything crystal clear. Just my preference.
