| Abstract: | 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. |
