It is neither the limitofsequence nor the limitof function, but it is a special limit in which it seems the description of variable and the change process of variable are not clear.
它既不是数列极限，也不是函数极限，而是一段特殊的极限。变量的描述比较模糊，没有清晰的变化过程。

Below by way of example, and I to talk about some method ofsequencelimit teaching experience.
下面通过例题的方式及本人的教学经验来谈谈数列极限的一些求法。
