不要以為 L'Hopital rule 是無敵。
請留意兩個情況:
lim(x→0) (e^x - 1)/x = 1 如果你用洛必達法則你必定犯了循環論證的錯誤。
請研究研究~
另外,洛必達法則也未必一定是最佳方法:

哦~
原來係咁~
我以為你的意思係想去用 L'Hopital rule 去 prove 添~

That is a wrong method!!!
This involves circular argument.
This is because (e^x - 1)/x → 1 as x → 0 is needed to prove that (e^x)' = e^x.
However, now you use (e^x)' = e^x to prove (e^x - 1)/x → 1 as x → 0.
