In mathematics, an ellipse (from the Greek for absence) is the locus of points on a plane where the sum of the distances from any point on the curve to two fixed points is constant.
An ellipse is a type of conic section: if a conical surface is cut with a plane which does not intersect the cone's base, the intersection of the cone and plane is an ellipse.
An ellipse centered at the origin of an x-y coordinate system with its major axis along the x-axis is defined by the equation of the elliptical object.
