Here are two ways to render a ^ (carrotcaret) in plain text within LaTeX:
\documentclass{article}
\usepackage[T1]{fontenc}
\begin{document}
A caret: \verb|^|
\end{document}
\textasciicircum
I tested them and both work as prescribed. They produce different carrotscarets.
(via comp.lang.texcomp.text.tex)

Not be a stickler, but I think you mean “caret” not “carrot”.
Hi Sean. Thanks for your graciousness.
I did mean caret; I am not sure why I wrote carrot! 🙂
