Equation of an ellipse


Ellipse is a curve on a plane surrounding two focal points such that a straight line drawn from one of the focal points to any point on the curve and then back to the other focal point has the same length for every point on the curve. The equation of an ellipse whose major and minor axes coincide with the X and Y Cartesian axes, relates the one-half of the ellipse’s major and minor axes with the Cartesian coordinates of any point of the ellipse.
