摘要
通过变量代换,将一类二阶变系数齐次线性微分方程化为常系数线性微分方程,并求出在不同条件下的通解公式.
By means of variable substitution, a class second-order homogeneous linear variable coefficients differential equation is turned into constant coefficients differential equation, and under different conditions, the general solution formulas are obtained.
