Java Laboratory for differential curves

Soumis par Antonio le mer, 2008/09/24 - 19:26.

This laboratory is designed to experiment and visualize the elemental concepts of differential geometry of curves in the plane or the space.
It is possible to use it in:
http://www.mat.uned.es/GeoCM/2PP/lab_curvas/_apps/matematica3d_20.app/ma...
(please be patient, some times our server is slow)
With this laboratory it possible to visualize the Frenet frame, osculatrix circle, evolute, osculatrix plane, ... and to compute curvature, torsion, arc length, ... of differential curves and to see nice animations.

Calculus course developed in a dual way, both in paper and as a Moodle course.

Maths for More has worked on the technical development of this course of Pearson Education.

Achilles, Turtle, and the Geometric Series

This is a short video that discusses the paradox of Zeno. It turns out that this paradox is not a paradox but rather an easy way to show that a geometric series converges (if |q| < 1) and to find a formula for the sum. Suitable for high schools.
