# Find a point on a circle which contains a rectangle using another point, the angle between the two and the rectangle's dimensions

I'm trying to construct a mathematical formula that will calculate a point (x,y) on a circle which contains a rectangle with a width w and height h, given another point on the circle (a, b) and the angle between them α. Has anyone encountered something like that before?

Thanks! Dan
