Students can draw graphs in a coordinate system. This program is good for especially high school students. The program makes it very easy to visualize a function and paste it into another program. Students can do calculations on the functions.
This site is dedicated to mathematical, historical and algorithmic aspects of some classical mathematical constants (like p, e, Euler's constant g, z(3), ¼). A few results on prime numbers are added. Easy and fast programs are also included and can be downloaded.
H. Freudenthal. Educational Studies in Mathematics, 1 (1/2):
3-8(May 1968)Systematization is a great virtue of mathematics, and if possible, the student has to learn this virtue, too. But then I mean the activity of systematizing, not its result. Its result is a system, a beautiful closed system, closed, with no entrance and no exit. In its highest perfection it can even be handled by a machine. But for what can be performed by machines, we need no humans. What humans have to learn is not mathematics as a closed system, but rather as an activity, the process of mathematizing reality and if possible even that of mathematizing mathematics..
