WebThe simplest method to determine the equation of an ellipse is to assume that centre of the ellipse is at the origin (0, 0) and the foci lie either on x- axis or y-axis of the Cartesian plane as shown below: Both the foci lie on the x- axis and center O lies at the origin. Let us consider the figure (a) to derive the equation of an ellipse. WebThe ellipse is the set of points which are at equal distance to two points (i.e. the sum of the distances) just as a circle is the set of points which are equidistant from one point (i.e. the center).
