摘要
本文介绍运用待定系数法,求常系数非齐次线性微分方程特解的简便解法,它可由二阶推广到n阶.
In this paper, by using the undetermined coefficient method, a simple and convenient solution for special integral of inhomogeneous linear differential equation with constant coefficients was introduced. It can be extended from the second to the n-th order.
