About Desmos Graphing Calculator
Desmos Graphing Calculator is a free tool for plotting equations, tables and data. You type a function and see its graph appear instantly, and you can add sliders to change values and watch how the curve responds.
The app is popular in education because it makes it easy to explore relationships between expressions and pictures. The Google Play listing describes the company's aim of universal maths literacy. The latest App Store notes mention version history for graphs and support for the words and and or in restrictions, along with performance fixes.
The app is free and Google Play lists neither ads nor in-app purchases. It suits students, teachers and anyone who wants a clear, quick graphing calculator. Signing in lets you save graphs and share them. The company now operates as Desmos Studio, and older names such as Desmos Inc may still appear in some places. It is a graphing tool rather than a full computer algebra system.
Sign in to keep your graphs. It does not replace a computer algebra system for symbolic work.
