The radial distance of a body to another can be given by:

(x+a)^2 + (y+b)^2 = r^2

where x is the independent variable, y is the dependent, r is the radius
from the center of the "circle" and a and b are the center (location) of
the body around which you are rotating.

solve for y.

increment x and watch it go!
