How can I get mathematical symbols in verbatim mode? If I use them, for example \equiv, it is just reproduced as is in the pdf.

It sounds like you don't really want verbatim (which means produce the output, erm, verbatim). What do you really want? –  TH. Apr 21 '11 at 5:10

I want to include some code. For that I want to use the verbatim mode so that I dont have to do all the indentation, etc. And in that code, there are some symbols. What can I do? –  n1kh1lp Apr 21 '11 at 5:11

You can use alltt, fancyvrb or listings package for this purpose.

For fancyvrb, see manual "4.1.16 Catcode characters". Example:

\begin{Verbatim}[commandchars=\\\{\},
  codes={\catcode‘$=3\catcode‘^=7}]
x=1/sqrt(z**2) ! $\frac{1}{\sqrt{z^2}}$
\end{Verbatim}

It is easier to use listings package, see manual "4.14 Escaping to LaTeX". Example:

\begin{lstlisting}[mathescape]
// calculate $a_{ij}$
$a_{ij} = a_{jj}/a_{ij}$;
\end{lstlisting}

I think you might try the alltt package.
