【Abstract】 It is discussed on how to apply the theory of ordinary differential equations about the solving process of linear differential equations with constant coefficients to solve the problem about cyclic number sequence of the second order equations in the recursive number sequence, thereout, we can see the directive function of the higher mathematics to elementary mathematics.更多还原
