Ok, and where did the limit of h go ??
Plus, you, can you go from there ?
*After l'H˘pital's rule, power series, here comes the newly trend : MacLaurin series !*
No I have always liked power series more it was just I was not adept enough at LaTeX yet to use them...now I am...and yes you could go from there...technically the answer would be ∞ due to an infinite amount of ∞ + an infinite amount of 0's...but as you pointed out I read the question wrong so that limit does not apply
