Desmos is an advanced graphing calculator implemented as a web application and a mobile application written in JavaScript[1]. It was founded by Eli Luberoff - a math and physics double major from Yale University,[2] and was launched as a startup at TechCrunch's Disrupt New York conference in 2011.[3] As of September 2012, it had received around 1 million US dollars of funding from Kapor Capital, Learn Capital, Kindler Capital, Elm Street Ventures and Google Ventures.[4] 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.[5][6][7]

Users can create accounts and save the graphs and plots that they have created to them. A permalink can then be generated which allow users to share their graphs and elect to be considered for staff picks. The tool comes pre-programmed with 35 different example graphs for the purpose of teaching new users about the tool and the mathematics involved.[8]

A modified version of the calculator has been used in standardized tests, such as the State of Texas Assessments of Academic Readiness test and the Virginia Standards of Learning (SOL's).[9] Moreover, activity modules for classrooms can be created through a teacher account, which allow instructors to view students' work and response in real-time.[10]

Another peculiar use of the calculator involves the creation of graphic arts — which involves an elaborated use of curve modelling through equations and inequalities.[11][12] As of April 2017, Desmos also released a browser-based 2D interactive geometry tool, with supporting features including the plotting of points, lines, circles and polygons.[13][14]
