用递推的方法求极限Ⅱ

本文给出两个推论;之后,又通过严格的数学证明,把此类问题进一步推广,给出了三个定理。至此,数学上一大类型的数学求极限的问题迎刃而解。

In this paper,after investigating a special problem, we get a different method and using it we wonderfully get a result. Then we do much researching on the same kind of problems deeply and obtain two interesting corollaries. Next we generalize the conclusions and arrive at three theorems Finally we summarize the discussion to form a idea which will be easily used to deal with a kind of limit problems.
