Abstract
Discuss the particular solution of 2nd-order constant coefficient non-homogeneous linear differential equation yn+py'+qy=eλxpm(x) .At first suppose the polynomial in particular solution by using pending coefficients method,and then find the coefficients by solving the matrix equation they satisfied.So some new formulas are obtained,which simplify the course of finding the particular solution.关键词
