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

I had:

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

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