But you are right that the bounds of the interval of the integral (r to r-q) are wrong.
You have to have bounds in terms of definitive values of x.

Imho the right way would be to integrate from -1 to 1 if the circle has its center on 0 or from 0 to 2 if the center is at x=1.

But i am really to lazy to do it right now
