Is there any capability to label arcs as we may label line segments, i.e., $\overline{AB}$? I can't seem to find anything that allows us to use the tricks I see online within MathJAX.

Something like $\newcommand{arc}[1]{\stackrel{\Large\frown}{#1}}\arc{AB}$?

$\newcommand{arc}[1]{\stackrel{\Large\frown}{#1}}\arc{AB}$

It's not great if you want a three-letters arc, though: $\arc{ABC}$. Still does the trick, I suppose.

  • $\begingroup$ Thanks Asaf. That is fine here. Unfortunately, I failed to mention that it is for the blog, where MathJAX is a bit inferior. $\endgroup$ – Ron Gordon Apr 6 '15 at 11:16

How about

$\overset{\mmlToken{mo}{⏜}}{ABC\,}$

which produces $\overset{\mmlToken{mo}{⏜}}{ABC\,}$?
