# How to typset the symbol “^” (caret/circumflex/hat)

I need to display the symbol '^'

d <- dist(fascores, method = "euclidean")^2

How do I do that?

 Answers from How to look up a symbol are valid in this case. However, there are more options for circumflex than for most symbols ;) – tohecz Feb 25 at 8:01

You can use

• in text-mode (needs \textrm or similar in math-mode)
• \textasciicircum or
• \^{},
• in math-mode
• \hat{} (only this produces a circumflex),
• \widehat{}, or
• \wedge (∧).
• in a verb-like manner

• \string^,
• \char\^,
• \verb!^!:

\verb!d <- dist(fascores, method = "euclidean")^2!

## Overview

### Code

\documentclass{standalone}
\usepackage{upquote}% getting the right grave  (and not ‘)!
\begin{document}
\begin{tabular}{lcc}
Input                   &       Text       &                 Math                  \\ \hline
\verb|\string^|         &     \string^     &              $\string^$               \\
\verb|\char\^|         &     \char\^     &              $\char\^$               \\
\verb|\verb!^!|         &     \verb!^!     &              $\verb!^!$               \\ \hline
\verb|\textasciicircum| & \textasciicircum &                  ---                  \\
\verb|\^{}|             & \^{} (e.g. \^a)  &                  ---                  \\ \hline
\verb|\hat{}|           &       ---        &       $\hat{}$ (e.g. $\hat a$)        \\
\verb|\wedge|           &       ---        &      $\wedge$ (e.g. $a\wedge b$)      \\
\verb|\widehat{}|       &       ---        & $\widehat{\ }$ (e.g. $\widehat{abc}$) \\
\end{tabular}
\end{document}

 Another for the list: \char\^, which may be slightly more robust in some rare cases I can't think of off the top of my head. – Will Robertson Feb 25 at 4:54 @WillRobertson Very good. Added it to the list. Is the \ mandatory in some cases? – Qrrbrbirlbel Feb 25 at 5:20
