Approximating Functions with Chebyshev Polynomials

Authors:
Codruţa Chiş, F. Creţ

In this paper, are reminded the most important, from the point of view of approximation theory, properties of Chebyshev polynomials and give a short Maple procedure to compute the coefficients of the Chebyshev-Fourier Series expansion of a continuous function on the interval [-1,1].
