Desmos (graphing)

Desmos is an advanced graphing calculator implemented as a web application and a mobile application written in JavaScript. It was founded by Eli Luberoff, a math and physics double major from Yale University, and was launched as a startup at TechCrunch's Disrupt New York conference in 2011. , it had received around 1 million US dollars of funding from Kapor Capital, Learn Capital, Kindler Capital, Elm Street Ventures and Google Ventures. 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 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 36 different example graphs for the purpose of teaching new users about the tool and the mathematics involved.
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). Moreover, activity modules for classrooms can be created through a teacher account, which allow instructors to view students' work and response in real-time.
Another peculiar use of the calculator involves the creation of graphic arts – which involves an elaborated use of curve modelling through equations and inequalities. 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.
The name "Desmos" came across the "Greek word Desmos that means link, or connection, or bond"
