HTML5 Applet to Explore Equations of Ellipses

Interactive Graphing and Exploration Tool

An HTML5 applet to explore the properties of the graph of ellipses whose equations are of the form \(\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1\). Use the interactive controls below to change the parameters \(h\), \(k\), \(a\), and \(b\) in real time.

Ellipse Parameters

\(h =\)

\(k =\)

\(a =\)

\(b =\)

💡 Note: Adjust center coordinates \((h, k)\) and semi-axes lengths \(a\) and \(b\), then click "Plot Ellipse" to update the graph canvas.
