GeoGebra is a dynamic mathematics software for education in secondary schools that joins geometry, algebra and calculus.
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, offers commands like Root or Extremum and finds derivatives and integrals of functions.
These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa.
Requirements:
· Java 1.4.2 or later
What`s New in This Release: [ read full changelog ]
· If the Points Export_1 and Export_2 exist, they will be used to define the export rectangle (Export_1 and Export_2 must be within the visible area)
· Checkbox now consistent across all platforms
· Options -> Checkbox Size -> Regular/Large
· Perpendicular check added to "Relation between two objects" Tool
· Messages from "Relation between two objects" Tool rewritten
· Angular Bisector Command and Tool renamed to Angle Bisector
· Line Bisector Command and Tool renamed to Perpendicular Bisector
· BMP import (Java 1.5+)
· Unicode fonts used in LaTeX equations
· LaTeX equations exported at full resolution
· in SVG and PDF export, option to export text as editable text or shapes. Stores the text either as text (lets you edit the text in eg InkScape) or as bezier curves (ie guaranteed to look the same even if the correct font is not installed).
· support for inline equations and linefeeds in LaTeX eg "if x=9 find $ \sqrt{ x } $"
· Angle entered in rotate dialog box is remembered (if it is in degrees)
