Publisher review:GeoGebra is a dynamic mathematics education application for secondary schools that unites algebra, geometry, and calculus.
GeoGebra allows you to create constructions using points, lines, conic sections, vectors, segments, functions and to dynamically modify them when needed.
Moreover, all the equations and coordinates used in your constructions may also be entered directly.
Thus, GeoGebra has the ability to deal with variables, points and vectors, provides you with commands like Root and Extremum and allows you to easily finds derivatives and integrals for functions.
Requirements:Operating system:Mac OS X
