Mathbot down
Hi Oleg. Just a heads-up that Mathbot hasn't run in over 24 hours. I'm guessing that this is related to wikitech:News/Toolforge Grid Engine deprecation, for what it's worth. Extraordinary Writ (talk) 06:31, 21 December 2023 (UTC)


 * He is inactive for a long time, with fewer than 50 edits last year. Just a random Wikipedian (talk) 03:20, 23 December 2023 (UTC)


 * I will take a look tomorrow. Oleg Alexandrov (talk) 03:35, 23 December 2023 (UTC)
 * I migrated the bot to the new way of doing things. Thank you for your note. I will keep an eye on it for a while. Oleg Alexandrov (talk) 20:52, 23 December 2023 (UTC)

Your comment on De Moivre Talk Page
On the De Moivre Talk page you say:

By De Moivre's formula:


 * $$(-1)^{1/2} = \left(\cos \pi + i \sin \pi\right)^{1/2} =\cos \frac {\pi}{2} + i \sin \frac{\pi}{2}= i\,$$

but also
 * $$(-1)^{1/2} = \left(\cos 3\pi + i \sin 3\pi\right)^{1/2} =\cos \frac {3\pi}{2} + i \sin \frac{3\pi}{2}= -i\,$$

so you get two different answers which is not good.

Why do you think it is not good that there are two square roots. Is it also 'not good' that, for example, 3 has two square roots? Can you please explain why it's not good?37.228.204.111 (talk) 18:01, 5 February 2024 (UTC)
