MathGraphs

Graph any equation of the form f(x, y) = g(x, y)

Drag to pan · Ctrl+scroll or pinch to zoom

Both sides in terms of x and y. Press Enter to graph.

Evaluate f(x, y, z)

Entering equations

Enter an equation in x and y of the form f(x,y) = g(x,y), then press Graph. Both sides are required — for example x^2/9 + y^2/4 = 1.

Ranges

The four range boxes take numbers as well as constant expressions such as 2*pi, pi/2 or sqrt(2). You can also drag the graph to pan, and zoom with Ctrl+scroll, a pinch, or the − range / + range buttons; the boxes follow along. A plain scroll always scrolls the page.
