The outer outlines of the letters 'o' and 'O' in Zapf's Melior typeface are described by superellipses with n = log(1/2) / log (7/9) ≈ 2.758. WebThe standard equation for a circle is (x - h)2 + (y - k)2 = r2. The center is at (h, k). The radius is r . In a way, a circle is a special case of an ellipse. Consider an ellipse whose foci are both located at its center. Then the center of the ellipse is the center of the circle, a = b = r, and e = = 0 .
