根据Legendre多项式的正交性,利用一个组合恒等式,得到由Legendre多项式表示x^2n和x^2n+1的具体形式,进而建立了Legendre多项式和Chebyshev多项式的关系式.
Based on the orthogonality of the Legendre polynomials and combinational method,x^2n and x^2n+1 expressed by the combinatorial sums of the Legendre polynomials in this paper.Then according to these identities,Chebyshev polynomials and Legendre polynomials are connected with each other in definite forms.
