anonymous · Answer

Is this your question?
$$\large \lim_{x \rightarrow +\infty} \frac{\ln(x)-1}{x^2}$$

anonymous · Answer

yes :)..how did u do that?

anonymous · Answer

Apply l'hopital rule because it is infinity/infinity form

anonymous · Answer

Do you know l'hopital rule ??

anonymous · Answer

to tell the truth i dont know this..but i'll google it :)
Thank you very much for the help ^_^
