摘要
提出了数值微分公式的代数精度的概念,给出了利用待定系数法确定数值微分公式,并求出其余项的一种新方法.此外,利用该方法,可以证明某些含微分中值的等式问题.
A new concept of algebraic precision of numerical differentiation formulae was introduced, and a new method of solving numerical differentiation formulae and its remainder term were obtainel by using waiting-decision coefficient method. In addition ,some equality problems including differential mid-value were proved by using this method.
