Introduction to Conic Sections

Ellipses - Example 1

In mathematics, an ellipse is a curve in a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. The two focal points (also called the foci) are the endpoints of the major axis of the ellipse. The length of the major axis is called the "semimajor axis" of the ellipse, and the distance between the two focal points is called the "semiminor axis". The shape of an ellipse is represented by its eccentricity, which for an ellipse can be any number from 0 (a circle) to arbitrarily close to, but not equal to, 1 (a line). The eccentricity of an ellipse is the ratio of the distance between the foci to the length of the semimajor axis. A circle has an eccentricity of exactly one, and an ellipse can have an eccentricity that is any real number greater than zero.
