In this section you will find some links to many useful programs in mathematics. You can also download some materials at the bottom of the page.

## Computer algebra system

Computer algebra systems (CAS) can be used to deal with the most of the school problems concerning algebra, analysis, equations and systems of equations, trigonometry, vectors and matrices, differential analysis and integral calculus.

## Dynamic geometry software

Dynamic Geometry Software (DGS) allows creating geometrical pictures that are dynamical. More precisely, pictures in which points can be moved (using the mouse) without losing the defined relationships between the geometrical objects. It can also be used to create interactive applets and the associated HTML documents, i.e. dynamic worksheets.

## Other

 Mathematik alpha http://mathematikalpha.de/ Mathematics alpha consists of a comprehensive lexicon and several hundred subprograms on many topics of school mathematics, but also interdisciplinary problems of physics, astronomy and computer science. Poly http://www.peda.com/poly/ Poly is a shareware program for exploring and manipulating geometrical bodies. MatheAss http://www.matheass.de/ Math Assistant is first intended for a target group composed by students and teachers of Gymnasium. Nevertheless, it can also be used by any people that are interested in math. The program solves most of the problems arising from Algebra, Geometry, Calculus, Stochastic, and Linear Algebra. POV-Ray http://www.povray.org/ POV-Ray is a 3D raytracer for creating three-dimensional bodies or structures. The source text-based editing, however, requires a certain amount of training. Descartes3D http://www.descartes-media.de/ Descartes3D is a vector tutorial for use at general education schools, vocational schools, colleges and universities. It allows the creation of three-dimensional objects in a virtual scene in which the viewer can move freely. Funkyplot http://www.studienkreis.de/funkyplot The freeware program Funkyplot is a powerful feature plotter, which impresses with its diverse output options. MatheGrafix http://mathegrafix.de/ MatheGrafix is an easy-to-use, very good feature plotter. You can plot functions and integrate the corresponding pictures within documents. The program is freeware.
