comment Branch points of the Lambert W function
I should have asked this question earlier, but why can we necessarily understand the behavior of $W(z)$ near $z= - \frac{1}{e}$ by looking at $|W(z)|$?

comment Branch points of the Lambert W function
Do you know if the definitions being used by Mathematica differ from the definitions given in this paper on page 16? And why does my profile page say I haven't cast any votes today? I upvoted your answer shortly after you posted it.

revised Interesting log sine integrals $\int_0^{\pi/3} \log^2 \left(2\sin \frac{x}{2} \right)dx= \frac{7\pi^3}{108}$
I added a necessary restriction.

Thank you. And I wasn't accusing you of copying a part of my answer.
