## Lesson 6-4: Hyperbolas

Mike May, S.J., 2/14/06, Created with GeoGebra

## Objective:

The student will be able to define a hyperbola, graph a hyperbola, locate its center, vertices and foci.

The applet lets you review constructions for ellipses and hyperbolas.

The center of the conic can be moved by dragging. The major axis is parallel to the x-axis.

The distance from the center to a vertex on the major axs and the distance from the center to a focus are controlled by sliders.

The point on the conic can be moved by dragging it.

A hyperbola is the set of points for which the difference of the distances from the foci is a fixed constant.

An ellipse is the set of points for which the sum of the distances from the foci is a fixed constant.
