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 ...

The standard equation for circle is x^2 + y^2 = r^2. Now divide both sides by r and you will get. x^2/r^2 + y^/r^2 = 1. Now, in an ellipse, we know that there are two types of radii, i.e. , let say a (semi-major axis) and b (semi-minor axis), so the above equation will ...
