##\delta^3(\vec{r})##

How do you evaluate it?

What are its values from -inf to +inf?

Beyond that, I would say that you should try a bit harder to learn about the delta function without just asking us to explain it. It is typically introduced in either a Quantum mechanics course or an Electromagnetism course. Griffiths text on both subjects gives a non rigorous intro to the delta function.

##\delta^3(\vec{r}) = \delta(r_x)\delta(r_y)\delta(r_z)##
