| Abstract: | The solution methods of the differential array equations are proposed to study,research and summary.Five kinds of methods are given,namely the method of characteristic root,of settling constant,of decline mark,of decline mark to multiply by q,and of recursion.From that,we can see the technique and vivid of problem solving in the elementary mathematics,and the logic of conversion from unknown to known. |
