许多函数在其参数为零而不是一个很小的正数时才会表现出质的不同 #183

是不是改为 “许多函数在其参数为零和很小的正数之间会表现出极大的差异” 更好一些?原翻译更像直译。

英文原文: “Many functions behave qualitatively differently when their argument is zero rather than a small positive number.”

@jcq15 像这样翻译会造成误解“许多函数在其参数为零和很小的正数之间会表现出极大的差异”,比如读者可能会认为参数是0.0001,它在“零和很小的正数之间”,会表现出极大的差异。实际是参数为0和0.0001会表现出很大的差异,比如f(x)=1/x。
