Understanding Ellipse Properties
An ellipse is a closed curve where the sum of the distances from any point on the curve to two fixed points (foci) is constant. In the standard form equation ((x-h)^2/a^2) + ((y-k)^2/b^2) = 1:
- Center (h, k): The midpoint of the ellipse.
- Semi-major axis (a): Half of the longest diameter.
- Semi-minor axis (b): Half of the shortest diameter.
- Orientation: Horizontal if a > b, vertical if b > a.
This calculator helps you quickly determine these properties from the equation and visualize the ellipse. Explore different equations to see how the properties change!
