I know that
1) when eccentricity is less than 1 then it is an ellipse
2) locus of points making sum of the distance from two fixed points(foci) with that point a constant, creates ellipse.
Here comes the question, I understand that locus made according to number 2, is ellipsoidal. But how can it give the same equation of an ellipse? Or in reverse way how the sum of the distance of any point on the ellipse from the foci is constant?
