单词	Chebyshev polynomials
释义	Chebyshev polynomials Mathematics Polynomials T_n(x) and U_n(x) which uniquely satisfy T_n(cosθ‎) = cosnθ‎ and U_n(cosθ‎)sinθ‎ = sin(n + 1)θ‎ for all θ‎. They are orthogonal polynomials on the interval (–1,1) with weight functions $w (x) = {(1 - x^{2})}^{1 / 2}$ and $w (x) = {(1 - x^{2})}^{- 1 / 2}$ respectively.
