How to look up a symbol?

I want to type ^ in mathmode, but \frown is too long, so my question is where to find a small version?

Update: Thanks to Mico. I tried \smallfrown, but it seems too big either.

amssymb has \smallfrown. I found this just using detexify. Please check first this How to look up a symbol? –  percusse Jun 25 '12 at 14:26
    
{\scriptsize\frown} if another font does not suit you? –  David Carlisle Jun 25 '12 at 14:26
    
I tried {\scriptsize\frown} but things didn't change. –  Popopo Jun 25 '12 at 14:47
    
sorry I meant \scriptstyle not \scriptsize –  David Carlisle Jun 25 '12 at 16:03
    
OK, I tried it, and frown became smaller. Thank you. –  Popopo Jun 25 '12 at 16:10

Here are some options for you that scales either \frown or \smallfrown (from amssymb) down to the size of \textasciicircum:

enter image description here

\documentclass{article}
\usepackage{graphicx}% http://ctan.org/pkg/graphicx
\usepackage{amssymb}% http://ctan.org/pkg/amssymb
\begin{document}
\textasciicircum $\frown$ \par
\textasciicircum \raisebox{.5em}{\smash{\scalebox{.5}{$\frown$}}} \par
\textasciicircum $\smallfrown$ \par
\textasciicircum \raisebox{.5em}{\smash{\scalebox{.5}{$\smallfrown$}}} \par
\end{document}

In the above MWE, both \frown and \smallfrown is raised to the level of \textasciicircum for comparison using \raisebox, and scaled down to 50% of its original size (via \scalebox from graphicx).

Depending on the choice, you should define a command that creates the frown you're after, like

\newcommand*{\myfrown}{\raisebox{.5em}{\smash{\scalebox{.5}{$\smallfrown$}}}}

say.

Wonderful, it works! Many thanks! –  Popopo Jun 25 '12 at 15:01

Have you tried \smallfrown (provided by the amssymb package)?

Yes, I have. But it seems too big either. I want to seek a smaller on as ^. –  Popopo Jun 25 '12 at 14:40

\textasciicircum{} or \^{} can be used within math mode using text mode
