OK, I have a circle and there is a point in the center. Given two locations on the circle I need to find the angle that is formed in the center. I know this can be done but I'm having trouble making this into an algorithm for a program...here is a diagram to help make my point.
The first point is the green one, now if the second point is any one of those purple points how can I find the new angle for the center?
