| Abstract: | It was promoted in this article that the function monotonous distinction proposition given in litera- ture [1]. Theorem 1 and 2 about ratio of two infinitely small quantity function monotonous are obtained. Using the result , it is easy to distinguish ratio of two infinitely small quantity function monotony and certify inequality. |
