Remarks
The angle of a point on an ellipse is measured by projecting the point along a vector perpendicular to the major axis onto a circle whose center is the center of this ellipse and whose radius is the major radius of this ellipse. The angle between the major axis of the ellipse, and a vector from the center of the ellipse to the intersection point with the circle, measured counterclockwise about the crossproduct of the major and minor axes, is the angle of the point on the ellipse.
