| Abstract: | This paper is devoted to providing a particular solution to find a kind of systems of three-dimensional second order differential equations with constant coefficients by means of undetermined coefficients.The non-homogeneous terms of differential equations are the form of trigonometric function multiplied by exponential function.Through some examples,the particular solution formulas are validated. |
