Description :
GeoGebra is a free, cross-platform dynamic math program for all levels of education, including geometry, algebra, tables, graphs, statistics, and arithmetic in one easy-to-use package.
In addition, the program has rich opportunities for working with functions (plotting graphs, calculating roots, extrema, integrals, etc.) due to the commands of the built-in language (which, by the way, also allows you to control geometric constructions). Unlike other programs for dynamic manipulation of geometric objects, the idea of GeoGebra is an interactive combination of geometric, algebraic and numerical representation. You can create structures with points, vectors, lines, conic sections, and math functions and then dynamically modify them.
GeoGebra allows you to directly enter equations and manipulate coordinates. Thus, you can easily plot functions, work with sliders to select the necessary parameters, look for symbolic derivatives, and use powerful commands like root and sequence.
About the program:
Graphics, algebra and tables are connected and fully dynamic
Easy to use interface with very powerful features
You can create interactive learning material yourself, such as web pages
Available in many languages for millions of users worldwide
Free open source software
Key features:
Curve construction
Construction of graphs of functions;
Construction of curves specified parametrically in the Cartesian coordinate system:;
Construction of conic sections : An arbitrary type of conic - by five points.
Circle : - in the center and a point on it;
- in the center and radius;
- at three points;
Ellipse - by two Focuses and a point on the curve;
Parabola - in focus and directrix;
Hyperbola - by two foci and a point on the curve;
3D modeling
Construction of the locus of points depending on the position of some other point belonging to some curve or polygon (Locus tool).
Calculations
Actions with matrices : addition, multiplication;
Transpose, invert;
Calculation of the determinant;
