## Main Question or Discussion Point

Can someone help me evaluate this integral?

[tex]

\int\limits_{-\infty}^{\infty} dz' \frac{1}{\sqrt{(x-x')^2 + (y-y')^2 + (z-z')^2}}

[/tex]

Mathematica is telling me that this guy diverges. But it CAN'T! This is supposed to give me the reduced Green's function for two semi-infinite plates that meet at a right angle on the z-axis.
