二阶常系数非齐次方程特解的求解

二阶常系数非齐次方程特解的求解,按照高等数学教材的公式计算,计算非常繁琐.给出了特解的两种简易算法,使特解求解的计算大为简化.;According to the formula in the textbook of higher mathematics,it is more difficult to obtain the particular solution to a second-order non-homogeneous equation with constant coefficients. In this paper, two easier calculations of the particular solutions are proposed to simplify this process
