| Abstract: | The definition of linear differential equation is briefly introduced. It is pointed out that the linear equations are the fundamental origin of the superposition theorem which hold true and is applied extensively. Finally, it is indicated that the linear equations are the fundamental that the complex exponential expression is carried out effectively. |
