Can ns ask because that the limit as $x$ approaches $\lim_x \to 0-\ln x$? you re welcome explain. Its because since the limit of a role only exist if the lim as $x$ ideologies some number $n$ indigenous both the confident and negative side is the same, ns not sure that im persuaded that the limit together $x$ philosophies $0$ because that $\ln x$ exists. I understand its an unfavorable infinity indigenous the positive side, yet from the negative side?

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

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

For a limit to exist, the two borders approaching from the left and also right side require to match up.

I.e. We need $$\lim\limits_x\to0^-\ln(x) = \lim\limits_x\to0^+\ln(x)$$ to it is in true.

Since $\ln(x)$ is not defined for $x\leq 0$ assuming us are assessing over the reals, the left-hand border can"t be evaluated, and also thus the limit does not exist.

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