If ab then we have x2a2 y2a21. The sum of two focal points would always be a constant. When ab the ellipse is a circle and the perimeter is 2pa 62832.
The formula generally associated with the focus of an ellipse is c 2 a 2 b 2 where c is the distance from the focus to center a is the distance from the center to a vetex and b is the distance from the center to a co-vetex.
