Use this applet to help you answer questions about the properties of ellipses and their equations. [br][br]Move the sliders left and right to change the value for: a,b,h, or k[br]The point P represents all of the points around an ellipse. Move it around to see the values for the distances to the foci: F_1 and F_2.[br]The equation for the ellipse is shown as well.
