Chebyshev polynomials of the first kind are defined as Tn(x) = cos (n*arccos (x)). These polynomials satisfy the recursion formula. Chebyshev polynomials of the first kind are orthogonal on the interval -1 ≤ x ≤ 1 with respect to the weight function . Chebyshev polynomials of the first kind are special cases of the Jacobi polynomials.

04.04.2016 · Answers (2) You can easily enough build the first kind Chebyshev polynomials in symbolic TB form. (Or second kind if you wish.) Then you get the coefficients by a dot product. Don't forget to divide by 1/sqrt (1-x^2) in the dot product. As these polynomials are generated, don't forget how they are normalized.
