Everyone is so modest that they're giving semi-selfish reasons like: It's for my ego (half joking). I think teaching is fun. It helps me learn. I want to give back to the community that answered my questions. Those are all true, but somebody just needs to say the real reason: it's for the greater good. I post on math.stackexchange because helping people ...

Let's see: The fact it was talked about on another math forum I used to visit. The fact I'm too lazy to clean. The fact that I know parts of different levels of ideas, and think differently. The fact it's a legal possibility. The fact I can do it without getting out of bed. The fact it distracts me from suicidal ideation. The fact it combines interest and ...

Depends on who you want to attract. Not everybody will go to a "help me" title. Typically , they either need knowledge about the area used to solve the question, or they would waste their time by looking at the question. Not everybody has deep knowledge in all areas, so more advanced question would be skippable. However , if they don't know what's ...

Reopened Please reopen Solving $2\cos \left( \frac{\pi }{2}-\theta \right)=3\cos \left( \frac{\pi }{3}+\theta \right)$ for $0 < θ < 2π$. This question was closed as a duplicate by the Community bot, yet it is not remotely related to Find all $x$ that satisfy $3 \cos{2x}=-1$ for $0^{\circ} \leq x \leq 180^{\circ}$, or the previous versions of the ...

I think I must answer this question , piecing together a couple of things from my comments and other experiences that I've had on this site. I'll put it in a table format. I'll answer the more general question : what to do when you see a question with interesting mathematical content that could be closed under one of the MSE guidelines. First, however, a ...

Even if something is too localized, it might have a larger community a few years later and get answered at that point. As long as the question is well defined and ample thought has been put into it I think we should err on the side of letting things stay.

You can use dcases from mathtools, although I don't know how it works since I tried using the require command and it didn't work. You can find the package and the environment here. For $\rm\LaTeX$ though, it makes the subfunctions render in a displayed style.

The tag hadamard-product has the following usage guidance: Wiki: Hadamard product of $A$ and $B$, $m\times n$ matrices, Hadamard product is defined entrywise. Excerpt: For questions about Hadamard product between two matrices, or it can concern analytic functions. I feel that there should ideally be two different tags, one for the Hadamard product of ...

This question might be a little off-topic for Math Meta—you are likely to get a better response from tex.se. However, since typesetting is often an issue on the main Math SE site, I suppose that this question is also in-scope here. Don't use \choose. The \choose command is a plain TeX command, and is not really appropriate for use in LaTeX. Instead, use ...
