Finally I found out what my profile is good for: I can abuse it as a clipboard!

@: Welcome to tex.sx! A tip: you can use backticks `\`` to mark your inline code as I did in my edit.

@: Welcome to tex.sx! A tip: If you indent lines by 4 spaces, then they're marked as a code sample. You can also highlight the code and click the "code" button (with "101010" on it).

@: Welcome to tex.sx! Note that you don't have to (and shouldn't) sign with your name since it automatically appears in the lower right corner of your post.

@: I tidied up your question a bit, hope that's OK.

I think your question is answered [here](). (Possible duplicate?)

@: Can you please add a [minimal example](http://meta.tex.stackexchange.com/q/228/1235) that illustrates your problem?

comment {(x+y)}^2 or (x+y)^2?
@einpoklum: What I meant: For me, the parentheses () do already bunch the formula together, so there's no need for braces.

comment {(x+y)}^2 or (x+y)^2?
@einpoklum: Well, I'm a mathematician, so I don't see inappropriate semantics here - why should I surround parentheses with braces? I agree that this feature of the typesetting engine is cumbersome, but it's less a design choice than a limitation of computers from the late seventies, when the choice was made. It would of course be great if LuaTeX or some other engine would offer better typesetting in such a case.

@Niel: Wow, how did they manage to clearly distinguish between the two?

comment Can I get a \widebar without using the mathabx package?
@Darling: You could ask a new question, referring to this answer.

comment Negative phantom
@Fictional: Yes, that's correct. And I wrapped the whole thing into a \mathop so that before and after it you also get the same spacing as for \cos.

comment Negative phantom
I probably wouldn't do it, but in this situation you could use \mathop{\rlap{$\sin$}\hphantom{\cos}} instead of a negative phantom.

comment Why \allowbreak is not working?
Note that, by default, there's no stretching or shrinking of the spaces after commas (\thinmuskip) in math.
