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: g: 3x + 4y = 7 or c: (x - 2) 2 + (y - 3) 2 = 25
and a number of teams, including differentiation and integration. The most remarkable feature of GeoGebra - double representation of objects: every expression in the algebra window corresponds to an object in the geometry window and vice versa.
Key features:
• Interactive graphic models, work with algebra and tables
• Work from school level to the level of the institute
• Free training materials
• Graphics, algebra and tables are connected and fully dynamic
• Easy to use interface, in addition, has a very powerful
• You can create an interactive learning material, such as a Web page
• Available in many languages ??for users around the world
Deriving:
• Plotting functions y = f (x);
• Construction of curves defined parametrically in Cartesian coordinates: x = f (t); y = g (t);
• Construction of conic sections:
• • Konica any form - by five points.
• • Circle:
- In the center and a point on it;
- In the center and radius;
- By three points;
• • Ellipse - on two foci and a point on the curve;
• • Parabola - to focus and directrix;
• • Hyperbole - two foci and a point on the curve.
• Construction of the locus of points depending on the position of some other point belonging to a curve or a polygon (a tool Locus).
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.
