Sure, it may happen that you can't evaluate lim f'(x)/g'(x). But that doesn't mean it's wrong and you can't use it. 3) OP asked for limit. He didn't specify how to find it. The response "you can't use it" implies there is something wrong with it and only you know what it is. Have you thought about a career in journalism slick?

Yes that is the reason. But in physics it is allowed to use it if it works. Last edited by idontknow; January 30th, 2019 at 06:33 AM.
