Semi-major / semi-minor axis of an ellipse
(Complete Item Description)
- Abstract:
An interactive applet and associated web page that show the semi-major and semi-minor axes of an ellipse. The applet has an ellipse whose major and minor axis endpoints can be dragged. As they are dragged the semi-major and semi-minor axes change length and may swap places. The applet also shows the location of the foci, which are always on the major axis, and shows how they move with variation of the semi-axis lengths. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
