x = cx + r * cos(RadianAngle)
y = cy + r * sin(RadianAngle)
r = radial distance between x, y and cx, cy or r = SQR((x-cx)^2 + (y-cy)^2)
Yeah, for graphics it is really useful in plotting points (x,y) about another point (cx, cy): a given distance ( r ) and a given angle (RadianAngle = _D2R(DegreeAngle) ) from another point.
