On the Number of C-points in a Circle on the Tiling(3.6.3.6)
摘要/Abstract
摘要:
用Chebyshev多项式的零点为节点的Lagrange多项式逼近高阶多项式时,误差公式中出现一类n项和数。现给出此类和的表达式,并用归纳法证明之
Abstract:
When Lagrange polynomial, with its node being the null of Chebyshev polynomial, approximates the higher order polynomial, there will be a type of n- term sum in the error formula. Give an expression to this type of sum and provide proof for it by means of induction.
