 Rigorous Gradient Calculator

Compute the gradient of a function
using rigorous interval arithmetic.

Rigorous Graphing Applet

Graph functions and find their roots.
All results are verified, no second guess necessary.
 Cascade Applet

Rigorously solves the
initial value problem
for discrete, planar maps.
A powerful new algorithm produces guaranteed error bounds in form of
zonotope
enclosures. This avoids the wrapping effect.
