摘要
一般多项式都可以展开为正交多项式的级数形式,而勒让德多项式、厄米特多项式和拉盖尔多项式都是典型的正交多项式。文章研究了xn关于这些正交多项式的级数展开及其它们相互之间的级数展开。
All ordinary polynomials have series expansion of orthogonal polynomials, while Legendre polynomials, Hermite polynomials and Laguerre polynomials are special orthogonal polynomials. This article studies about series expansion of x^n by these orthogonal polynomials and their series expansion each other.
