摘要
在假设变系数二阶线性齐次微分方程两个线性无关解的比值已知的前提下,从这个比值入手去倒推变系数二阶线性齐次微分方程的基本解组,从而得到两类变系数二阶线性齐次微分方程通解的非级数求法.
Assume that the ratio of two linearly independent solutions is known on variable coefficient linear homogeneous second-order differential equations. Then the fundamental solutions for variable coefficient second-order linear homogeneous differential equations are given by the reverse deduction method. Hence, the non-series solutions on two types of variable coefficient second-order linear homogeneous differential e- quations are obtained.
