    Question Quick Vector Field question

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

    I had:
    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.

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