Math & Science ⇒ Widehat in mathmode

[juliette]

If I want a hat to appear over-top of many consecetive symbols I can use \widehat{abc} rather than \hat{abc}, but I can't seem to do it for the command \bar{abc}. Is there any way to widen the bar??

Hi,

you could use the \overline command or perhaps the more sophisticated \overbracket command provided by the mathtools package:

Code: Select all

\documentclass{article}
\usepackage{mathtools}

\begin{document}

$\overline{abc}$

$\overbracket[.7pt][0pt]{abc}$

\end{document}
