For years, I've been using a hobbled together command to get the arc notation as used in the textbooks adopted by high schools in my area. I'm not really all that pleased with the result: it's just barely tolerable. I figured someone in the community here might have a better solution to what I've been getting by with for several years.

%% my poor man's solution to arc notation

    \arc{AC} \\

  • Check texdoc symbols-a4 for \wide and especially \wideparen. – Qrrbrbirlbel Feb 4 '13 at 3:13

    Did you see the related question frown and mathop/stackrel/overset? You can use \widearc with the kpfonts or fourier packages, but these change your fonts. \wideparen from yhmath or a few other packages, mentioned there, also works. – Nick Matteo Feb 4 '13 at 3:16

A solution along the lines of Werner's, but that avoids its shortcomings, first of all the dependency on tipa:






$\arc{AC}$ $\arc{BAD}$ $\arc{ICK}$ $\arc{GOOD}_{\arc{xyz}}$


enter image description here

A different solution with the yhmath font:




$\wideparen{AC}$ $\wideparen{BAD}$ $\wideparen{ICK}$ $\wideparen{GOOD}_{\wideparen{xyz}}$

    Always something to learn from your answers. Thank you. – A.Ellett Dec 27 '15 at 19:01

tipa's \texttoptiebar looks useable:

enter image description here

\usepackage{graphicx,tipa}% http://ctan.org/pkg/{graphicx,tipa}
\arc{AC}\ \arc{BAD}\ \arc{ICK}\ \arc{GOOD}

  • This is my preferred solution, however note that the command \arc is already part of other packages such as "unitsdefs", "eepic", "pict2e". I suggest using \ark instead. – c05772 Jun 25 '15 at 19:23
  • There are so many errors here! Box 9 should be assigned globally (or box 8) should be used; \ooalign must be enclosed in a group. The text is not in math mode as required in the question. – egreg Dec 26 '15 at 20:39
