Conic - Ellipse

Drag the center to reposition the ellipse. Observe how the equation changes as you move the ellipse. Use sliders "a" and "b" to change the lengths of the major and minor axes. Trace point "A" to observe how the sum of the distances to the foci remains constant at all points on the ellipse. Observe how changing the lengths of the major and minor axes changes the focal length and eccentricity.
