积分因子:一些具体求法

Integrating Factor: Method of Some Reliable Findings

本文提出求积分因子的两种切实可行的求法,暂定名力“矩阵法”与“公式法”。应用这两种方法,往往可求出一些较复杂的积分因子,为解相应的微分方程提供方便。

The two methods of some reliable findings of integrating factor are presented in this paper. It is named 'matrix method' and 'formula raethod'. By these two methods we can determine, some more ecmplexed integrating factors. It is more convient for us to solve corresponding, differential equations,
