摘要
首先利用推广的分部积分法导出一阶线性方程组的两个特解公式,然后将有关的结果应用到高阶线性方程(组),得出了特解的一些新公式。
Firstly, using an extended integral method by parts, two formulae of the particular solutions of the first-order nonhomogenous linear differential equations are derived. Secondly, the related results are applied to the higher-order linear differential equations with constant coefficients. Some new formulae of the particular solutions are thus obtained.
