二阶常系数非齐次线性微分方程初值问题几种解法的比较

Comparison of Solution Method to the Original Values Two Order,Constant Coefficient, Non-homogeneous Linear Differential Equations

研究了二阶常系数非齐次线性微分方程在自由项不同情况下，用三种不同的方法，求初值问题的解；并进行比较，得出了一些有用的结果。

Three solution method, under four condition of free terms, for the original values of two order,condi constant coefficient, non-homogeneous linear differential equations were analyzed and compared in this paper. Some practical results have been achieved.
