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 ...

17.12.2021 · The Chebyshev polynomials of the first kind are a set of orthogonal polynomials defined as the solutions to the Chebyshev differential equation and denoted T_n(x). They are used as an approximation to a least squares fit, and are a special case of the Gegenbauer polynomial with alpha=0. They are also intimately connected with trigonometric multiple-angle formulas.
