Provides mathematical solutions for solving 2D and 3D graphing, geometry, algebra and economical problems like statistics. Via the graphical interface, it constructs and analyzes conic sections, polygons, etc. Also working with graphs also got easier with the touch-screen interface.
GeoGebra is a powerful mathematics tool for everybody, who is concerned with geometry. This program allows you to build drawings of almost any complexity. You can add points, lines, vectors, polygons, circles, angles, text and even images from files (.gif, .jpg, .png, .tiff) to your drawings. All objects have bindings to coordinates. So you may get to learn various information like distance or length, area, angle, equation. Besides standard figures, there are many additional elements for editing (parallel line, semicircle, locus, mirror at line, bisector, etc.). Every element can be changed dynamically afterwards. Just type-in an equation in the form and the element will be added ('(x-3)^2+(y-5)^2=100' for the circle). The program has a very user friendly and beautiful interface and, what is more, it is absolutely free. GeoGebra is very fast, and works steadily. You may export the resulting image as a picture or save it on the disk in a special format. Also you can print your drawing (with scale mark) out.

- the CAS View supports exact versions of some of the geometry commands, and there is now some support for parametric curves
- PSTricks and PGF/Tikz export enhanced with fixes & more objects supported
- HTML worksheet export now uploads to GeoGebraTube (Ctrl-Shift-M to get new automatic Java/HTML5 export to the clipboard)
- Ctrl-Shift-B to copy the "ggbBase64 string" to the clipboard
- (a,1) draggable
- Autocreation of sliders from the Input Bar (eg y = a x + b)
- Variables highlighted in the Input Bar and CAS
- Text Tool: Quotes " replaced with “ or ”.
- defaults changed: Checkboxes, Sliders and Buttons now larger
- angles over 360 degrees are allowed now
- angle default can be set to 0° - 180°
- now set angle properties for lists of angles
- automatically updates to latest version (Windows)
