The Chebyshev Polynomials: Patterns and Derivation
www.focusonmath.org › sites › focusonmathAug 20, 2004 · that the polynomials are generated. All the zeros for Chebyshev polynomials are between –1 and 1. In fact, because t k (cos q) = cos kq, the zeros of the kth Chebyshev polynomial are of the form cos q, where cos kq = 0. Since the cosine is 0 at odd multiples of p/2, the zeros of t k (x) are of the form, where 1 ≤ q ≤ 2k – 1. A detailed derivation of this
Chebyshev polynomials - Wikipedia
https://en.wikipedia.org/wiki/Chebyshev_polynomialsThat is, Chebyshev polynomials of even order have even symmetry and contain only even powers of x. Chebyshev polynomials of odd order have odd symmetry and 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 are sometimes called Chebyshev nodesbecause they are used as nodes in polynomial interpolation. …
