| Abstract: | This article eliminated a doubt when an important function limit is used in getting the limit of duality function. This paper gave a positive answer and also gave an explanation for a misunderstanding in getting the limit of duality function. Standing on the viewpoint of the paper, the author expanded the method of getting the limit of duality function in getting the limit of irrational expression. |
