GeoGebra - Geometry, Algebra and Calculus Freeware

GeoGebra is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and calculus. GeoGebra is written in Java. On the one hand, GeoGebra is a dynamic geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards.

On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum.

These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa.

GeoGebra can also be used to create dynamic worksheets.It runs in many languages, including English, French, German, Portuguese and Italian.
