| Abstract: | The Taylor formula is of important position in mathematical analysis. The definitions of the second-order differential of one or two variable function were proposed on the basis of its first-order differential of one variable function. The differential forms of the Taylor formula of one or two variable functions were also presented. Accordingly, the new form of Taylor formula is the same as that of the traditional Taylor formula, and the approximate calculation precision can then be enhanced. Some examples were given to show the salient natures. |
