[ SmokeDetector | MS ] Few unique characters in body, no whitespace in body (190): Find all functions $f: \mathbb{R}\rightarrow \mathbb{R}$ satisfying a functional equation ✏️ by AngelBaVy on math.SE

@JyrkiLahtonen It probably needs to be closed again, as the OPhas edited it back into a PSQ.

Also, the OP's other question happens to fall in the same category.

PSQ

PSQ2

PSQ

@DevashishKaushik At least now the question makes sense. It may even be true, fianally :-) Yeah, it is still a PSQ, but now there is some hope to turn this into a real question. I don't know what's best.

[ SmokeDetector | MS ] No whitespace in answer (95): If $\cos\theta=\frac{\cos\alpha+\cos \beta}{1+\cos\alpha\cos\beta}$, then prove that one value of $\tan(\theta/2)$ is $\tan(\alpha/2)\tan(\beta/2)$ by Tsr on math.SE

@user21820 @MikeMiller @Lord_Farin @Did : Items D2 - D19 need one additional deletion vote each. Thanks.

[ SmokeDetector | MS ] Mostly non-latin answer (50): What is Var(X - Y)? by user645681 on math.SE

Ugh... PSQ as audit.
