This is the portable edition of GeoGebra, an open-source interactive mathematics application that facilitates tools for calculus, algebra and geometry. This educational utility primarily caters to students and teachers.

As installation is not a prerequisite, you can drop the program files anywhere on the disk, and run the executable file directly.

It is also possible to move GeoGebra to a USB flash disk or similar storage unit, in order to run it on any workstation without prior installers, as long as it has Java installed.

More importantly, the tool does not insert new entries into the Windows registry, Start menu or any other areas of the computer.

The interface is made from a regular window with a user-friendly structure, where a few drawing tools are displayed on the upper part of the screen. You can rearrange the two primary panes dedicated to algebraic expressions and graphics, as well as sort the algebraic items by type, dependency, layer, or construction order.

You can add new points to a line, function or curve in the graph, create points inside an object or on its perimeter, attach/detach points, intersect two objects, display a midpoint or center of a segment, circle or conic, as well as generate complex numbers.

Other graphical functions let you create perpendicular or parallel lines, polygons and circles, use a compass, generate a list of angles, translate objects by vectors, insert text and images, inspect functions, zoom in and out, and dozens more. Each expression shown in the Algebra panel can be traced in the graph, animated, or marked as an auxiliary object.

The project can be saved to file for further modifications, shared on the developer's website, printed, as well as exported to file (e.g. HTML, PNG, EPS, GIF), while the settings can be saved as default.

GeoGebra supports multiple languages and font sizes, and allows advanced users to manage tools. It has a good response time and works smoothly, while using a moderate-to-high amount of system resources. To sum it up, GeoGebra provides all the necessary tools (and more) for helping math users create presentations and projects.

Requirements: Java

What's New in This Release:
- New Tools: Plane, Right prism, Sphere, View in front of
- New Features:
Extended types to 3D: Points, Vectors
Cross product: Lines, Segments, Rays, Polygons, Circles
- New Object Types:
* Surfaces: eg f(x,y) = sin(x * y), eg Function[sin(a * b), a, -5, 5, b, -5, 5]
* Planes eg x + y + z = 1
* Pyramids
* Prisms
* Spheres
* Cylinders
* Cones
- 3D View:
* Applets: 3D export to applets is not supported at the moment
* Moving objects: left-drag points in the 3D view. Click on the point to change the mode "along xOy plane" to "along z axis", and so on
* Translation of the scene: shift+left-drag the 3D view (without pointing on a moveable object), use move view tool
* Rotation of the scene: "Rotate 3D graphic view" tool, right-drag the 3D view (without pointing on a moveable object), continue rotation when mouse released, view in front of an object (toolbar)
- Zoom: use wheel mouse, use zoom tool
- Gridlines: show/hide axes, grid, xOy plane
- Commands: Improved Commands
