Hi,
I'm stumbled on the following integral,
[itex]\int d\vec{q} e^{i\vec{q}\vec{r}} \cos(2\theta)[/itex],
where [itex] \theta[/itex] denotes the angle of the vector [itex] \vec{q} [/itex] and the [itex] \vec{r}[/itex] is an arbitrary vector. The integral domain is a circular area of radius [itex] D [/itex].
Could anyone help me out ?
Many thanks.
