摘要
采用待定系数法,给出了非齐次项为指数函数与n次多项式乘积的二阶常系数线性微分方程组的通解公式.
By applying the method of undetermined coefficients, in this paper we discuss the general solution to a kind of systems of second - order differential equations with constant coefficients where non - homogeneous term is the product of exponential function and the polynomial of degree n.
