This is the equation of an ellipse: (x-h)²/a² + (y-k)²/b² = 1. Adjust the sliders to see how these factors influence the ellipse.

2. What happens when k gets larger? Smaller?
3. What happens when a gets larger? Smaller?
4. What happens when b gets larger? Smaller?
5. Can you form a circle? How?
6. What has to happen to form an oval? How can you make this oval "stand up"? How can you make it "lay down"?
