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:

(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.
