GeoGebra for MAC

GeoGebra for Mac is an interactive mathematics software for free. The aim of this software is to connect numeric, geometric and algebraic representations in an interactive approach. You can construct mathematical representations using geometric objects, figures, text, animations, scripting and other functions. You can directly enter and control coordinates and equations. You can work with sliders, create plots and define points in a path or region to determine parameters. You can find perform powerful commands and look for derivatives such as sequence or root. GeoGebra constructions are built using objects, tools, functions, expressions and commands provided by the software. The main window is divided into two default views, Algebra View on the left and Graphics View on the right. Above these views are the Menubar and the Toolbar. You can place Navigation Bar below the two. You can use keyboard shortcuts to use features, or accessibility features like virtual keyboard. Menus include File, Edit, View, Options, Tools, Window and Help. There are 4 types of views: Algebra, CAS, Graphics and Spreadsheet. Dialogs include Properties, Construction, Tool Creation, Tool Manager, Redefine, Options, Export Graphics, Export Worksheet and Print Preview. You can publish your work online at GeoGebraTube. You can print your GeoGebra works together with the Construction Protocol. Your image files can be saved in different formats. GeoGebra for Mac requires PPC/INTEL, Mac OS X 10.4 or later.

GeoGebra for Linux

GeoGebra is an open-source mathematics application used in schools that combines dynamic algebra, geometry and calculus. It is written in Java and available on multiple platforms. You can create dynamic constructions using the tools and objects in GeoGebra. Geometric objects include lines and axes, points and vectors, functions, curves, inequalities, conic sections and arcs. Lists of points, loci, lines, arcs, polygons, conic sections, functions, intervals and single variable equalities are called paths. Lists of other paths are paths, too. You can define the point belonging to a path using Point Command. Each point on the path has path parameter ranging from numbers 0 to 1. You use the PathParameter Command to determine this parameter. You can also define a point to a region [arc, conic, polygon, two variable inequalities] using Pointln Command or Point on Object Tool. General objects are numbers and angles, Boolean values, complex numbers, lists, matrices, images and texts. Action objects are useful in making interactive worksheets with scripting. They are: checkboxes> graphical representations of Boolean values; input boxes> text inputs for scripts; buttons> trigger scripts when clicked; comboboxes>only available in Spreadsheet View, a combination of buttons and checkboxes in Speadsheet Tab. Object properties include visibility, fixed objects that cannot be moved, deleted or redefined, filling [standard, hatch, image] and advanced features such as conditional visibility, layers and dynamic colors. There are 3 types of objects in GeoGebra: free objects> do not depend on other objects for position or value; dependend> depend on other objects; auxiliary> defined by user or created by specific tools. You can make labels and captions, change values, select and name objects, do automatic or manual animation of numbers, angles and points. Repetition of an animation cycle could be increasing, decreasing or oscillating [alternate between increasing and decreasing]. You can also do tracing and scripting using JavaScript and GGBScript.
