Het gratis Java programma GeoGebra is eveneens een aanrader. Zoals uitgedrukt in de help bij het programma: "GeoGebra is a mathematics software that joins geometry, algebra and calculus. It is developed by Markus Hohenwarter at the University of Salzburg for mathematics education in schools.
On the one hand, GeoGebra is a dynamic 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 window corresponds to an object in the geometry window and vice versa.". |
