摘要
研究了二阶变系数微分方程y″+P(x)y=Q(x),在适当条件下将其转换为二阶线性常系数微分方程,并得到其通解。应用该方法,可求出许多变系数微分方程的通解。
In this paper,the solvable of the various coefficient second order differential equation is studied.The condition that the various coefficient second order differential equation transfers into constant coefficient equation is given.Some solvable results are extended.
