A series of free, online video lessons with examples and solutions to help Algebra
students learn about ellipse conic sections.

The Ellipse
:

An ellipse is an important conic section and is formed by intersecting a cone with a plane that does not go through the vertex of a cone. The ellipse is defined by two points, each called a focus. From any point on the ellipse, the sum of the distances to the focus points is constant. The position of the foci determine the shape of the ellipse. The ellipse is related to the other conic sections and a circle is actually a special case of an ellipse.

Conic Sections: Introduction to the ellipse.
