摘要
运用常数变易法研究三类二阶变系数线性微分方程的求解问题,给出了可求得其解的判别条件和相应的通解公式,从而提供了求解变系数线性微分方程的新途径。
Solutions of three kinds of second-order linear ordinary differential equations with variable coefficients are studied by using the method of variation of constant,the critical conditions for solving the equation and the corresponding general solution formulas are given,thus a new approach for solving the linear ordinary differential equation with variable coefficients is provided.
