摘要
本文讨论了两个重要极限公式、洛必达法则以及等价无穷小代换在确定型和不定型幂指函数求极限过程中的应用,给出并证明了相关定理.最后通过实例验证了这些方法的有效性和实用性.
In this paper,the methods and theorems for the limit of definite and indefinite forms of power-exponential functions are provided and proved by using two limit formulas,L'Hospital's Rule,and equivalent infinitesimal.The validity and practicality of these theorems are examined.
