Desmos is a blockchain built on top of the Cosmos SDK and based on the Tendermint consensus engine specific for social networking apps. It uses game theory and on-chain governance to decentralize the business model of social networks prioritizing the interests of users. Instead of numerical coordinates, use expressions in terms of t, like (cos t, sin t). Graph lines, curves, and relations with ease. Whether you’re interested in form, function, or both, you’ll love how Desmos handles parametric equations.

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 36 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).[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]
The name Desmos came across the 'Greek word Desmos that means link, or connection, or bond'[15]

Practice
All of these calculators comply with the feature requirements of STAAR. These are a great option for practicing before use on Testing Day.
Testing Day
Students can use either Test Mode or Desmos District Test Mode on Testing Day.
Test Mode
Test Mode can be used on Chromebooks, iPads, and iPhones through iOS and Android app stores. Learn more on our Test Mode information page.
Desmos District Test Mode
Desmos
Since 2015, districts have been testing with Desmos during STAAR. Based on educator feedback over the years, we’ve built Desmos District Test Mode: the simplest and most secure way to use the Desmos calculators on Testing Day. To make sure using the Desmos calculators during STAAR is a smooth experience for IT departments, testing proctors, teachers, and students. Two key features:
Desmos Calculator Scientific Online
Ensures students use the right calculator built specifically for STAAR: IT administrators can centrally pre-select the STAAR calculators, ensuring that students will use the correct tools on Testing Day. This mitigates the risk that students accidentally select a calculator customized for a different state.
Allows proctors to more easily scan the room: Desmos Districts displays a different color and title on the top bar of each calculator used during an assessment. This second layer of security allows proctors to visually verify whether a student is using the correct calculator for their grade level—even from across the room.
