GeoGebra — The Complete Guide: Graphing, Geometry and CAS in One Place, and What the Licence Allows
GeoGebra combines a graphing calculator, interactive geometric construction, 3D graphing, probability and symbolic algebra (CAS) in one app, Calculator Suite. It runs in the browser, on desktop and on phones, and engineers and students use it for quick checks and for illustrating problems in teaching.

Who may use it free
GeoGebra is free for non-commercial use, mainly by students and teachers at home, at school and at university. Use intended to generate revenue or a commercial advantage — selling materials, paid training, non-academic books or advertising — needs a licence agreement with GeoGebra. The source code is released under the EUPL, but the installers and services are limited to non-commercial use.
