Okay I wish to try to construct an Epsilon-Delta Definition to prove the L'Hopital's Rule (0/0 form). Please correct me if I am wrong.(adsbygoogle = window.adsbygoogle || []).push({});

http://mathforum.org/library/drmath/view/53340.html

I found the above site. Scrolling down one would the proof.

I can follow how an x constraint is constructed. But then for the y constraint, I cannot seem to completely follow the proof when it says:

lim f'(x0)/g'(x0) = L

x0->b-

Any help/guidance will be appreciated
