摘要
利用待定系数和比较系数法,给出了一类五阶常系数常微分方程y^(5)+my^(4)+ny"+py″+qy′+ry=(a_0+a_1x+a_2x^2+a_3x^3+a_4x^4)e^(λx)的特解公式,对这类方程的求解具有一定指导意义.
: By using the method of undetermined coefficient and comparing coefficient, the special solution formula of fifth order ordinary differential equation with constant coefficient is given. The formula takes important effect in solving this kind of the differential equation.
