Chebyshev polynomials - Wikipedia
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…

Chebyshev/Orthogonal Polynomial Model
abaqus-docs.mit.edu › 2017 › EnglishChebyshev orthogonal polynomials are a common type of orthogonal polynomials that are particularly useful for equally spaced sample points. They are used when the sampling strategy is an orthogonal array. Isight implements Taguchi’s method (Taguchi, 1987) of fitting Chebyshev polynomials from an orthogonal array.

This note summarizes some of their elementary properties with brief proofs. 1 Cosines We begin with the following identity for cosines. cos((n + 1)θ) = 2cos(θ)cos(nθ) − cos((n − 1)θ) (1) This may be proven by applying ...
