Ellipses with Center at (h,k)

(please wait while the applet loads...)

The applet below lets you explore the graphs of ellipses with center at (h,k).
These ellipses have equation

• When p=q, the ellipse is a circle.
• When p>q, the major axis lies along the x-axis.
• When p<q, the major axis lies along the y-axis.

Use the sliders to explore the effects of changing the values of p, q, h, and k.
