Hi, I'd just like someone to verify my answer to the following: My answer (after much working out and simplifying): $\displaystyle \nabla \cdot F = \frac{3}{\sqrt{x^2+y^2+z^2}}-\frac{x^2-y^2-z^2}{(x^2+y^2+z^2)^{3/2}} $

Here's what I got $\displaystyle \nabla \cdot F = \frac{3}{\sqrt{x^2+y^2+z^2}}-\frac{x^2+y^2+z^2}{(x^2+y^2+z^2)^{3/2}} = \frac{2}{\sqrt{x^2+y^2+z^2}} $
Ah, thanks. I knew I messed up the signs in the last bit.
