| Abstract: | The symbolic calculation functions of Mathematica software are introduced in this paper, and according to the numerical calculation method of initial problems, Mathematica software is applied to symbolic calculations. Thus a symbolic calculation method of initial problems is built up. The sample indicates that this method is simplified and easy to programme and that the results of calculations are superior to those by the numerical method. |

| Keywords: | Mathematica symbolic calculations initial value problem iteration method |
