Properties of an Ellipse (Foci on the y-axis)

2020-03-10 00:40
This GeoGebra applet demonstrates the geometric properties of an ellipse with foci on the y-axis. It visually illustrates core parameters like the major and minor axes, foci, vertices, focal distance, and eccentricity. Users can drag a point to observe the defining property that the sum of distances to the two foci is constant, aiding the understanding of ellipses in coordinate geometry.
