Ellipse is a closed curve that can be obtained from a circle after an affin transformation. Ellipses are found in many areas of mathematics, physics and other sciences. Definition Ellipse can be defined as a geometric place of points, the sum of the distances from which up to two fixed points called tricks is equal to a constant value. This constant value is called the length of the large axis of the ellipse. Basic properties The ellipse has two symmetry axes that pass through the tricks. The...
