Homework Statement
Hi
I have the following integral over wavevectors inside the Fermi circle (we are in 2D)
[tex]
\int {dk_x \int {dk_y \sin ^2 \left( {k_x x} \right)} }
[/tex]
Ok, so I know that kx2+ky2=kf2, so ky2=kf2-kx2 - this takes care of ky. But what about kx? What should this run from in order to integrate along the vector running from the origin to kf?
Niles.
