I'm having troubles solving integrals in the Ideal Fermi Gas theory.
In particular the ones of the type:

$$ 
 \int\frac{d\vec{k}}{(2π)^3}θ(k\_F − k)( \vec{k} \cdot \vec{q})^n$$

but I actually don't understand how to do all types of integrals in the theory, and can't find a good reference explaining it.
