两类二阶变系数非齐次方程求解方法

摘要

The solutions to some kinds of second-order non-homogeneous linear differential equations with variable coefficients were discussed by using constant coefficient method and invariant method. The advantages and disadvantages of the two methods were analyzed and compared,and the feasibility of the two methods was illustrated by a concrete example.%使用常系数化法和不变量法对二阶变系数非齐次线性微分方程的求解问题进行了讨论,分析与比较了两种方法的优缺点,并通过具体的例子说明了方法的可行性.
