Scientific Computing

This module illustrates Chebyshev polynomials, their zeros, and their extrema.

The Chebyshev polynomials of the selected degree are plotted on the
interval *Chebyshev points*, can be
displayed. The Chebyshev points correspond to equally-spaced points on
a circle, but their values on the horizontal axis are not equally
spaced. The Chebyshev points have superior properties for polynomial
interpolation.
