|---|
| Type and technical scope: A free online graphing calculator that draws functions, plots points, shows equations visually, uses sliders and animates graphs. Scientific, four-function, geometry and 3D calculators also exist. | Type and technical scope: Dynamic mathematics software that combines geometry, algebra, spreadsheets, graphing, statistics and calculus in one engine. Separate apps cover CAS, geometry, 3D and scientific calculation. | Type and technical scope: A handheld graphing calculator with a polynomial root finder up to the 10th degree, a simultaneous equation solver for up to 10 equations, a numeric solver and a time-value-of-money solver, plus a spreadsheet app and unit conversions. | Type and technical scope: A system for technical computing built on the Wolfram Language, with nearly 7,000 built-in functions. Areas listed include symbolic and numeric computation, optimization, FEM, control systems and signal processing. |
| Programmability and integration: The Desmos API (v1.12) embeds the graphing calculator in a web page through a script with an API key. Four-function, scientific, 3D and geometry calculators must be enabled per key. | | Programmability and integration: All models support TI-BASIC. The Python Edition adds a Python programming environment. | Programmability and integration: Code, text and dynamic graphics are combined in the Wolfram Notebook Interface, with parallelism and GPU computing, and access to the Wolfram Knowledgebase. |
| Platform and hardware: Runs online in the browser, with no installation described on the page. | Platform and hardware: Web apps plus iOS and Android apps. Download pages are linked from the site. | Platform and hardware: Backlit 320 x 240 colour screen of 2.8 inches, rechargeable battery over USB, 3 MB flash and 149 KB free RAM. Approved for ACT, SAT, IB Diploma Programme and AP exams. | Platform and hardware: Runs on Windows, macOS, Linux and in the cloud. |
