Desmos is software for developing and sharing educational content. The Company built an advanced graphing calculator implemented as a browser application and a mobile application. In addition to graphing both equations and inequalities, it also features lists, plots, regressions, interactive variables, graph restriction, simultaneous graphing, piecewise function graphing, polar function graphing, two types of graphing grids — among other computational features commonly found in a programmable calculator. It can also be used in several different languages.
Users can create accounts and by doing so can save the graphs and plots that they have created. A permalink can then be generated which allows users to share their graphs and elect to be considered for staff picks. The tool comes pre-programmed with 35 different graphs for the purpose of teaching new users more about using the tool, or even about the mathematics involved.
