0~0与∞~0型极限的等价无穷小代换

0~0 and ∞~0 form of the limits replacing with equivalent infinitesimal

对于00与∞0型极限的极限,当函数比较复杂时,现有的方法求解困难.研究发现,通过等价无穷小替换幂指函数,将复杂函数化为简单函数后,可以有效求解.

For the 00 and∞0 form of the limits, the existing methods were not effective when the function was complex .The research provided that it could effectively solve the problem with equivalent infinitesi-mal replacing power exponential function , while the complex functions becoming simple .
