\[\lim_{x \rightarrow 1}\ln x \div x-1\]
OpenStudy (lgbasallote):
\[\lim_{x\rightarrow 1} (\frac{\ln x}{x-1})?\]
OpenStudy (lgbasallote):
coincidentally...if you substitute x = 1 right now..you'll get 0/0 <--you can use l'hospital
OpenStudy (lgbasallote):
pls tell me you know l'hospital....
OpenStudy (lgbasallote):
i hate limits that dont use l'hospital lol

yes I know
OpenStudy (anonymous):
and yes that is the right equation
OpenStudy (lgbasallote):
ahh wonderful!
OpenStudy (lgbasallote):
take the derivative of numerator and denominator
\[\frac{\frac{1}{x}}{1} \implies \frac 1x\]
now sub in
\[\lim_{x \rightarrow 1}\frac{1}{1} \implies 1\]
OpenStudy (lgbasallote):
do you get that?

trust me I'm just learning this stuff and I only have 3 weeks to get this Calculus class over.
OpenStudy (lgbasallote):
l'hospital is the only topic i remember from limits lol

lol

i suggest you practice your derivatives though...i believe that makes up 3/4 of the calculus I curriculum so if you master derivatives..you're good...and it'll make it easier for you to do l'hospital
