用积分因子解微分方程的意义分析

Analysis the Significance of use Integrating Factor to Solve Differential Equation

文章介绍了积分因子求解微分方程,它是一种积极有效的方法。若是常见的微分方程,可通过分析观察来确定,较难的微分方程可以采用方程左侧分组,再分别找出每组的积分因子,这样可使问题简化。

The article introduced to use integrating factor to solve differential equation, it is one positive effective method. If it is the common differential equation, may confirm by future analysis and monitoring, the more difficult ones we can use equation on the left side, and then find out the integrating factorof each group. Through this way, we can make the problem much easier.
