How do you simplify $lim_{xto 1+} e^{ln(x)cdot ln(ln(x))}$?
$begingroup$
I'm having an issue trying to figure out parameter to check for what parameter $b$ function is continuous.
$$
begin{cases}
arctanleft(frac{1}{x-1}right) &text{for $x<1$} \
a &text{for $x=1$} \
bcdot e^{ln(x)cdot ln(ln(x))} &text{for $x > 1$}
end{cases}
$$
In order to solve that, I need to figure out answer for
$$
frac{-pi/2}b = lim_{xto 1+} e^{ln(x)cdot ln(ln(x))}
$$
I wanted to use L'Hôpital's rule, but I'm having trouble substituting indeterminate form $e^{0cdot (-infty)}$ to $frac 00$.

Since the exponential function $xmapsto e^x$ is continuous, this boils down to
$$
lim_{xto 1+} ln(x)cdot ln(ln(x)).
$$
In order to apply L'Hôpital's rule, you can write this as
$$
frac{ln(x)}{ frac{1}{ln(ln(x))} }
qquadtext{or}qquad
frac{ln(ln(x))}{ frac{1}{ln(x)} }.
$$
You can also "simplify" this further by noting that
$$
ln(x)cdotln(ln(x)) = lnleft(ln(x)^{ln(x)}right).
$$
Again, since $ln$ is continuous you only need to calculate the limit of $ln(x)^{ln(x)}$. However, calculating a limit of a function of the form $f(x)^{g(x)}$ you would usually take the logarithm, so you get back to where you started.

If the limit exists, $$lim_{xto 1+} e^{ln(x)cdot ln(ln(x))}=e^{lim_{xto 1+}ln(x)cdot ln(ln(x))}$$
As you noted, this is a $0cdotinfty$ type. What you can do it is write it as $$ln(x)cdot ln(ln(x))=frac{ln(x)}{frac1{ln(ln(x))}}$$
This is $0/0$ type of limit. Or you can also get it into $infty/infty$ type $$frac{ln(ln(x))}{frac1{ln(x)}}$$
$endgroup$
$begingroup$
I'm probably misunderstanding something, but it seems to me that it would lead me to e^(0/0) which is not the same as 0/0, so i can't use L'Hôpital's rule. Am I wrong?

So you need to find

which is in the form $0(-infty)$. You can rewrite $ln(x)cdotln(ln x)$ to apply L’Hôpital’s Rule, such as by
