GeoGebra for Windows is a free and open-source dynamic mathematics software application. It[SQ]s designed for learning and teaching mathematics, and it runs on the Windows operating system. It allows users to create and manipulate various mathematical objects, including :

*

Geometry:

Points, lines, circles, polygons, conics, etc. You can explore geometric relationships and transformations interactively.
*

Algebra:

Equations, functions, graphs, and inequalities. You can see how algebraic expressions relate to their geometric counterparts.
*

Spreadsheets:

Organize data and perform calculations. You can link this data to other GeoGebra elements for dynamic visualizations.
*

Calculus:

Explore derivatives, integrals, and limits visually and numerically.
*

Statistics & Probability:

Create histograms, box plots, and other statistical visualizations. Simulate probability experiments.
*

3D Graphics:

Create and manipulate three-dimensional objects.

Essentially, GeoGebra provides a dynamic link between geometry, algebra, and calculus, making it a powerful tool for visualizing and understanding mathematical concepts. It[SQ]s used by students, teachers, and researchers alike. The Windows version offers all the functionality of the broader GeoGebra platform, optimized for the Windows environment.
