It can be shown that the Chebyshev polynomials T n(x) are orthogonal over the following discrete set of N+ 1 points x i, equally spaced on , i= 0; ˇ N; 2ˇ N ...

https://en.wikipedia.org/wiki/Chebyshev_polynomialsThat is, Chebyshev polynomials of even order have even symmetry and therefore contain only even powers of x. Chebyshev polynomials of odd order have odd symmetry and therefore contain only odd powers of x. A Chebyshev polynomial of either kind with degree n has n different simple roots, called Chebyshev roots, in the interval [−1, 1]. The roots of the Chebyshev polynomial of the first kind ar…
