摘要
通过寻求积分因子f1(x),f2(x),求解一类二阶线性微分方程,包括二阶常系数线性微分方程和二阶Euler方程.
By looking for the integral factor f1 （x） ,f2 （x）, we can get the general solution of a kind of second order linear differential equation, including second order linear differential equation with constant coefficients and second order Euler differential equation.
