Desmos Graphing Calculator

Enter a coordinate pair or equation in Desmos, then select a curve to inspect its points of interest. Labels can be pinned, and a point can be copied to the expression list or its coordinates copied separately. A defined function can be evaluated at chosen inputs or turned into a table; the guide's initial table uses x values from −2 to 2, which can be edited or extended. Pan, zoom or set explicit viewport bounds to inspect the relevant region. Audio Trace, opened with Alt+T, provides a nonvisual route with speed and volume controls. Saving to an account requires sign-in; the Share Graph menu provides a link or image export.
