have the right to i ask because that the limit as $x$ approaches $lim_x o 0-ln x$? you re welcome explain. Its because since the border of a function only exist if the lim together $x$ viewpoints some number $n$ indigenous both the optimistic and an unfavorable side is the same, ns not sure that im convinced that the limit as $x$ viewpoints $0$ because that $ln x$ exists. I know its an adverse infinity indigenous the optimistic side, but from the an adverse side?



The domain the $ln(x)$ is only positive reals, so the left-hand limit at 0 doesn"t really do sense.

You are watching: Limit of ln x as x approaches 0


For a limit to exist, the two limits approaching from the left and right side require to enhance up.

I.e. We require $$limlimits_x o0^-ln(x) = limlimits_x o0^+ln(x)$$ to it is in true.

Since $ln(x)$ is not identified for $xleq 0$ assuming us are evaluating over the reals, the left-hand border can"t be evaluated, and thus the limit does no exist.

If friend are analyzing over the facility numbers, that"s a somewhat various story, however given her wording, I"ve assumed that we"re talking around the reals here.
