GeoGebra is a free and multi-platform dynamic mathematics software for schools - for education in secondary schools that joins geometry, algebra and calculus. GeoGebra educational software is written in Java platform.

This educational software is a dynamic geometry system, that you can do all geometry operation: constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards.

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 - since we can entered directly equations and coordinates.

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