GeoGebra 4.4.5– Mathematics program for teaching and learning

[acervergel87]

​

GeoGebra – mathematics program for teaching and learning. With it, you can easily design a structure with points, vectors, segments, lines, conic sections. With some functions, you can dynamically change them.

GeoGebra this is a cross-platform dynamic mathematics program for all levels of education, which includes geometry, algebra, tables, graphs, statistics, and math, in one easy to use package. She has won several educational awards in Europe and the U.S..
Please note: The program requires a set in Java, so I suggest two options assembly.

GeoGebra an open source (GPL) dynamic geometry environment that allows you to create drawings in plane geometry, in particular, for constructions with ruler and compass.

In addition, the program rich possibilities of working with functions (graphing, calculating roots, extrema, integral, etc.) due to the built-in command language (which, by the way, allows you to manage and geometric constructions)
I must say that it is not just known for the Internet, and is gaining popularity by the day, including teachers of high school mathematics.

GeoGebra will help teachers to explain, and to familiarize students with educational materials not only geometry course, but the algebra and calculus, will be indispensable in practicing skills and visualization.
Very simply you can build up points, vectors, segments, lines, etc., as well as functions that can be changed dynamically with the mouse afterwards. On the other hand it is also possible direct input in the scale-notation:
and a number of teams, including differentiation and integration. The most remarkable feature of GeoGebra – double representation of objects: every E×ρréššion in the algebra window corresponds to an object in the geometry window and vice versa.

Key features:
Calculations:
Actions with matrices:
Addition, multiplication;
transposition, inversion;
The calculation of the determinant;
Calculations with complex numbers;
Find points of intersection;
Statistical functions:
The calculation of the expectation, variance;
The calculation of the correlation coefficient;
approximation of the set of points of a given type:
polynomial
exhibitor
logarithm
Sine
Working with Tables
The program allows you to create Java-applets, dynamic drawings to be included in a Web page.
