摘要
二阶常系数非齐次线性微分方程的特解一般都是用“待定系数”法求得的,但求解过程都比较繁琐。文章用初等积分法直接来求其特解,该方法简单、方便,且适用范围广。
In general, special solution of non-homogeneous linear equation of constant coefficient of the second order is obtained by the method of undetermined coefficient, but it’s process is too complicated. This article directly get it’s special solution by the method of elementary integrals, and the method is simple and has wider range.
