摘要
函数极限的计算是高等数学的重要内容。本文详细阐述了分式函数极限的计算方法,并重点分析了0/0型分式函数极限的求解方法:分解因式、有理化、等价无穷小替换、洛必达法则及上述四种方法综合应用约去零因子。
The calculation of function limit is an important part of higher mathematics.In this paper,the calculating method of the limit of fractional function is elaborated in detail,and the solving method of the limit of fractional function is emphatically analyzed:decomposition factor,rationalization,equivalent infinitesimal substitution,L’Hospital’s rule and the above four methods are combined to apply approximately zero factor.
