GeoGebra

GeoGebra is an interactive geometry, algebra, statistics and calculus application, intended for learning and teaching mathematics and science from primary school to university level. GeoGebra is available on multiple platforms, with apps for desktops (Windows, macOS and Linux), tablets (Android, iPad and Windows) and web.

GeoGebra's creator, Markus Hohenwarter,[1] started the project in 2001 as part of his master's thesis at the University of Salzburg. After a successful Kickstarter campaign, GeoGebra expanded its offering to include an iPad, an Android and a Windows Store app version.[2] At the same year it incorporated Bernard Parisse's Giac into its CAS view.[3] The project is now open-source and multi-lingual, and Hohenwarter continues to lead its development at the University of Linz.

GeoGebra includes both commercial and not-for-profit entities that work together from the head office in Linz, Austria, to expand the software and cloud services available to users.

Interactive geometry, algebra, statistics and calculus

GeoGebra is an interactive mathematics software suit for learning and teaching Science, technology, engineering, and mathematics from primary school up to the university level. Constructions can be made with points, vectors, segments, lines, polygons, conic sections, inequalities, implicit polynomials and functions, all of which can be edited dynamically later. Elements can be entered and modified using mouse and touch controls, or through an Input Bar. GeoGebra can store variables for numbers, vectors and points, calculate derivatives and integrals of functions, and has a full complement of commands like Root or Extremum. Teachers and students can use GeoGebra as an aid in formulating and proving geometric conjectures.

GeoGebra's main features are:

GeoGebra Materials Platform

The GeoGebra Materials platform[4] is a cloud service that allows users to upload and share GeoGebra applets with others. GeoGebra Materials was originally launched as GeoGebraTube in June 2011, and was renamed in 2016. As of April 2016 the service hosts more than 1 million resources, 400,000+ of which are public. "Materials" include interactive worksheets, simulations, games and e-books created using GeoGebraBook.

GeoGebra Materials can be also exported in several formats, including SVG, Animated GIF, Windows Metafile, PNG, PDF and EPS, as well as copied directly to the clipboard. GeoGebra can also generate code for use in LaTeX files.

Community

The International GeoGebra Institute (IGI) is the nonprofit arm of the GeoGebra Group. The institute coordinates research, development, translation and deployment efforts of the GeoGebra system across a global network of user groups at universities and non-profit organizations, as well as provide certification to GeoGebra experts and trainers.

gollark: We could have had a moon base. With vast stocks of nuclear weapons.
gollark: It's a shame that they never used Project Orion or any other vaguely ridiculous propulsion idea.
gollark: Try not doing that.
gollark: Did you not... sleep during that?
gollark: I can only focus on things with no practical application whatsoever. It's very """convenient""".
