Chebyshev 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.

It is known that Chebyshev polynomials are an orthogonal set associated with a certain weight function. In this paper, we present an ...

Chebyshev Polynomials John D. Cook∗ February 9, 2008 Abstract The Chebyshev polynomials are both elegant and useful. 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 ...

Orthogonal Series of Chebyshev Polynomials An arbitrary function f(x) which is continuous and single-valued, de ned over the interval 1 x 1, can be expanded as a series of Chebyshev polynomials: f(x) = A 0T 0(x) + A 1T 1(x) + A 2T 2(x) + ::: = X1 n=0 A …

The proof consists of letting x = cosθ and taking the real part of both sides of the geometric series 1 1 − teiθ = X∞ n=0 (teiθ)n. 4. Title: Chebyshev Polynomials Author: John D. Cook Subject: Basic properties fo Chebyshev polynomials Keywords: …

We observe that the Chebyshev polynomials form an orthogonal set on the interval −1 ≤ x ≤ 1 with the weighting function (1 − x2)−1/2.

That 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…
