Mathematical Ellipse Diagram with Focus Points

A comprehensive mathematical diagram illustrating the key features of an ellipse centered at the origin. It clearly labels the two foci, F(ae, 0) and F'(-ae, 0), along with vertices A, A', B, and B'. A generic point P(x,y) on the ellipse is shown, highlighting its relation to the focus F and the directrix x = a/e, which is also depicted.
