The definition of an ellipse is the set of all points such that the sum of the distances from two fixed points called the foci (plural of focus) is constant.

Webx^2+y^2=r^2, so 0 + 1 = 1. When y=0 then x=1. x^2+y^2=r^2, so 1 + 0 = 1. The equation itself doesn't match (0,0) (only if r=0, which is never the case), but the above method gives us a way to search the exact center of the ellipse. It's quite as simple as that. I hope my explanation helps you (and maybe others) to understand the concept behind ... WebEllipse (Graph & Equation Anatomy) Activity. Tim Brzezinski. Special Hyperboloid of 1 Sheet as a Locus.
