补充资料：洛必达法则
洛必达法则(l'hospital)法则，是在一定条件下通过分子分母分别求导再求极限来确定未定式值得方法。
设
(1)当x→a时，函数f(x)及f(x)都趋于零；
(2)在点a的去心邻域内，f'(x)及f'(x)都存在且f'(x)≠0；
(3)当x→a时lim f'(x)/f'(x)存在(或为无穷大)，那么
x→a时 lim f(x)/f(x)=lim f'(x)/f'(x)。
又设
(1)当x→∞时，函数f(x)及f(x)都趋于零；
(2)当|x|>n时f'(x)及f'(x)都存在，且f'(x)≠0；
(3)当x→∞时lim f'(x)/f'(x)存在(或为无穷大)，那么
x→∞时 lim f(x)/f(x)=lim f'(x)/f'(x)。
