A Particular Solution of a Nonhomogeneous nth Order Linear Differential Equation P (x, D) y=cose~x (or sine~x ) with Variable Coefficients
【摘要】 利用Lagrange参数交易法和初等行变换相结合的方法，给出了n阶变系数非齐线性方程p（x，D）y=cosex（或sinex）的特解．
【Abstract】 A particular solution of the form p (x, D ) y = cosex (or sinex ) Where p (x, D ) is alinear differential operator is obtained by combining the Lagrang’s method of variation of paraine-ters with elementary row operation.
