摘要
针对在高等数学的其它分支及相关学科中常常出现求解高阶非齐次线性微分方程的问题,首先采用分部积分法来求常系数高阶非奇次线性微分方程的解,然后通过变换y=ze^(λx),得出了一类高阶常系数微分方程的特解的简便方法.
Aiming at the frequent problems of solving high-end non-linear differential equations in other branches of higher mathematics and related disciplines, first of all, we use Division Integration Method for the singular solution of regular highorder coefficient of linear differential equations, and then through transforming y = ze^λx, we get the easiest way for the special solution of a class of high-order differential equations.
