WebIf there are two foci then there are two focal radii. Note: Using this second definition, the sum of the focal radii of an ellipse is a constant. It is the same as the length of the major diameter . The difference of the focal radii of a hyperbola is a constant. It is the distance between the vertices. Movie clip Web-If we draw two lines connecting any point on the ellipse to the two focal points, then the sum of the lengths of the two lines will be the length of the major axis-The ellipse consists of all the points with this property-The major axis is analogous to the diameter of a circle, which is twice the length of the radius-The semi-major axis of an ...
