The Ellipse - Berkner's Base for Physics and Math

Transformations on the Unit Circle: Consider an ellipse that is formed by stretching a circle horizontally or verically. X2 + y2 = 1 is a circle with center (0, 0) and radius 1 unit. (length of circle is 2) If it is stretched horizontally by a factor of “a”, then an ellipse is formed with vertices (-a, 0) and (a, 0) . Equation: ................
