Free DNS hosting, lets you fully manage your own domain. Dynamic DNS and Static DNS services available. You may also create hosts off other domains that we host upon the domain owners consent, we have several domains to choose from!
GeoGebra is dynamic mathematics software for all levels of education that joins arithmetic, geometry, algebra and calculus. On the one hand, GeoGebra is an interactive geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards. On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. These two views are characteristic of GeoGebra: an expression in the algebra view corresponds to an object in the graphics view and vice versa.
PyGeo is most fundamentally a framework for the creation of dynamic geometric constructions - i.e. constructions which embody defined and persistent geometric relationships responsive to real time on-screen interactivity.
PyGeo is, further, an implementation of this underlying abstract framework - exposing a range of geometric objects as the building blocks for virtual, dynamic geometric constructions.
The focus is away from Euclidian geometry and metrics, and toward later geometric and mathematical developments - particularly those connected with projective geometry of real space, and the geometry of complex numbers on the plane and on the unit (Riemann) sphere.
Geomview is an interactive 3D viewing program for Unix. Geomview lets you view and manipulate three-dimensional objects: you use the mouse to rotate, translate, zoom in and out, and so on. Geomview can be used as a standalone viewer for static objects or as a display engine for other programs which produce dynamically changing geometry. Geomview can display objects described in a variety of file formats. Geomview comes with a wide selection of example objects, and you can create your own objects too.
OpenEuclide is a 2D geometry software: figures are defined dynamically by describing formal geometrical constraints. This project is a basic tool for educational or modeling purpose. It is distributed under the GNU GPL licence, free and multi-platform (up to now, GNU and windows).
KSEG is a Free (GPL) interactive geometry program for exploring Euclidean geometry. It runs on Unix-based platforms (according to users, it also compiles and runs on Mac OS X and should run on anything that Qt supports). You create a construction, such as a triangle with a circumcenter, and then, as you drag verteces of the triangle, you can see the circumcenter moving in real time. Of course, you can do a lot more than that--see the feature list below.
KGeo is a program for interactive Geometry just like programs such as Euklid, Zirkel und Lineal or Kseg. It was my wish to write an open source version of this software that is free for schools and combines the best of both (all) worlds.
Kig is a program for exploring geometric constructions.
It is meant as a better replacement for such free programs as KGeo, KSeg and Dr. Geo and commercial programs like Cabri.
The dynamic mathematics software establishes new ways of teaching and learning mathematics. It offers opportunities of visualisation that can't be realised on paper or blackboard and with traditional construction tools.
Geometrix 3.5 possède toutes les fonctionnalités des anciennes versions de Geometrix auxquelles s'ajoutent de nombreuses nouveautés comme la possibilité de créer des animations, de revenir pas à pas sur une construction, de créer des boîtes noires, un nouveau traceur de courbes. ... La version déclinée ici donne de plus accès au compilateur de création d'exercices de construction et de démonstration. Géométrix dispose maintenant d'un assistant de preuve permettant au professeur de générer des exercices de démonstration.
GeoGebra is a free interactive geometry software for education in schools. Its creator, Markus Hohenwarter, started the project in 2001 at the University of Salzburg and is continuing it at Florida Atlantic University. GeoGebra is written in Java and thus available for multiple platforms.
