摘要
通过降阶给出求常系数二阶线性微分方程通解的一般公式,可通过不定积分直接求微分方程通解,并将这种方法进一步推广到n阶线性常系数微分方程的求解上.
In this paper,we contribute the general integral formula of second order linear differential equation with constant coefficients by means of decreasing order.So we can integrate directly to solve this kind differential equation.This solution is also generalized to the differential equation of n order.
