I don't understand the reopening of If $\sin(18^\circ)=\frac{a + \sqrt{b}}{c}$, then what is $a+b+c$? Could someone explain?

@YuiToCheng Once you see the third reopen-voter, who reopen it unilaterally due to a gold badge earned from answering PSQs in that area, you should know why...

and who also answered that question and got 5 upvotes

But since that question shows (some) effort, I do not object to that user answering it.

Agree the question is well-written... I just want to know his/her rationale behind the reopening. Otherwise, it seems an abuse of gold badges to me.

You can invite them to chat

Some other users with gold badges also do that

@YuiToCheng You probably haven't seen much of the rampant abuse of privileges by PSQ answerers.

@TheSimpliFire And it's almost never productive to invite them to chat.

@user21820 If @YuiToCheng has time to kill

Well, that's up to Yuito, and I shouldn't say more.

OK, I will leave a comment asking for the explanation anyway...

@YuiToCheng By the way, I disagree that this is a PSQ; the phrasing in "it might seem reasonable to expect [...] Is this correct, and if so, can [...] be given?" suggests that the question is motivated largely by curiosity and not undeserving reasons (e.g. cheating at homework). I'd rather have 10 of these than 1 of the PSQs that I regularly post in here. =)

@user21820 This is the "initial question" I'm referring to... All that follows are added by Robjohn

@YuiToCheng Oh okay thanks I followed the earlier link you provided and it had been beefed up, so I didn't know that.

@user21820 I will just point out that one of those posts has an entry in the reopen request thread.

@MartinSleziak Thanks! CC @XanderHenderson @JoséCarlosSantos @RRL

@quid @AlexanderGruber: I can't believe this is still happening, right on the front page...

@user21820 I closed it.

I love this question:

math.stackexchange.com/review/close/1202690

"Normally, I would just cheat. But Wolfram Alpha is giving me the wrong answers!"

@quid Please undelete this. The OP removed the question immediately after an answer is given.

@quid Thanks!

[This seems like a rather minor edit to make, in light of all of the other problems with that question. :](math.stackexchange.com/posts/3231780/revisions)

@XanderHenderson Lol. Weird things happen.

@TheSimpliFire @user21820 Just a friendly reminder that we should probably focus on posts, not people.

(for what it's worth)

I should have linked directly to the edit, now that I have made more modifications: math.stackexchange.com/revisions/3231780/2

:\

@XanderHenderson Yep. It was in response to the question "could someone explain"

@hola This is a chatroom for administrative stuff on MSE; you'd have better luck with these questions in the Mathematics chat

@hola This room is for discussing the closure, reopening, an undeleiton...

yeah... what @TheSimpliFire said...

got it. Thanks!

Oh, dear:

@XanderHenderson I stopped reading when they said that n = pi/2 when the condition was 0 <= n < pi/2

@YuiToCheng done

@quid Thanks!

This must be the fastest question I've seen so far on MSE to reach 10+ upvotes...

@YuiToCheng Multiple accounts perhaps, but that's only my personal suspicion

Usually wordy questions like this one (which is also low quality) don't attract many upvotes.

I think mathematicians hardly pay attention to the NBA...

@YuiToCheng Why would you think that? I don't see any reason to believe that mathematicians would be any less interested in the NBA than anyone else.

For example, a couple of colleagues of mine are trying to build a better algorithm for playing fantasy sports (including basketball).

@XanderHenderson Yeah, that's simply my prejudice. Ignore it.
