\frametitle{Objectives}
\label{sec-2}

At the end of this tutorial, you will be able to,
\begin{itemize}
\item Get acquainted to LaTeX.
\item Know why we prefer LaTeX ??
\item Know about the advantages and disadvantages of typesetting documents using the LaTeX approach.
\item Have a description, of a typical work flow; which uses LaTeX to typeset documents.
\item Recognize and differentiate between LaTeX commands, LaTeX comments and special characters, spacing and actual document content.
\item Create and compile a very simple LaTeX document.
\end{itemize}
\end{frame}

\frametitle{Pre-requisite}
\label{sec-3}

  Spoken tutorial on -

\begin{itemize}
\item Installing {\LaTeX}.
\end{itemize}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Introduction}
  \begin{block}{{\LaTeX} - Introduction}
    \begin{itemize}
      \item Typesetting program
       \begin{itemize}
         \item What is typesetting?
       \end{itemize}
      \item Excellently Typeset Documents - specially Math
      \item Anything from one page articles to huge books
      \item Pronounced \emph{Lah-tech} or \emph{Lay-tech}
    \end{itemize}
  \end{block}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Why {\LaTeX}?}
  \begin{itemize}
  \item Excellent visual quality! 
  \item Handles the typesetting; Lets you focus on content
  \item Makes writing math extremely simple
  \item It is a standard -- widely used in Scientific community
  \end{itemize}
  \begin{block}{}
    \[\tilde{N}_{\mathbf{x}}\times \mathbf{r}(\mathbf{x}) f_{1k}(\mathbf{x},t) - \frac{1}{2} \tilde{N} \tilde{N}:\mathbf{BB}^{T}P(\mathbf{x},t) = -m_{k}f_{1k}(\mathbf{x},t) + 2 \mathop{\mathbf{\aa}}_{j=1}^{K} f_{1j}(\mathbf{x},t)m_{j}P_{k|j} \]
  \end{block}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Why \LaTeX? \ldots}
  \begin{itemize}
  \item {\LaTeX} is a document based mark-up
  \item Mark-up $\rightarrow$ a system of annotating text, adding extra
    information to specify structure and presentation of text
  \item Document based markup $\rightarrow$ you don't have to worry
    about each element individually 
  \item Allows you to focus on content, rather than appearance.
  \end{itemize}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Advantages of using \LaTeX }
  \begin{itemize}
    \item Easy availablity of professional templates.
    \item Typesetting complex formulae in a convenient environment.
    \item Can start typesetting with very little effort.
    \item Presence of a lot of add-on packages.
    \item Encourages creation of well structured texts.
  \end{itemize}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Disadvantages of using \LaTeX }
  \begin{itemize}
    \item Designing whole new layout is difficult.
    \item LaTeX is not a word processor.
  \end{itemize}
\end{frame}

\begin{frame}[fragile]
  \frametitle{\LaTeX \ input file format}
  \begin{itemize}
    \item \LaTeX takes ASCII text file as input.
    \item We can compile \LaTeX files into DVI,Postscript or PDF files.
    \item \alert{Note:} \typ{latex} vs. \typ{pdflatex} 
  \end{itemize}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Commands,Comments\&Special Characters }
  \begin{itemize}
    \item {\LaTeX} is case sensetive.
    \item Commands begin with a \typ{\\}
    \item Environments have a \typ{\\begin} and \typ{\\end} 
    \item Any content after the \typ{\\end\{document\}} is ignored
  \end{itemize}
\end{frame}

\begin{frame}[fragile]
  \frametitle{Commands,Comments\&Special Characters \ldots}
  \begin{itemize}
    \item Anything that follows a \typ{\%} symbol till end of the line
      is a comment 
    \item Special characters (\typ{\~ \# \$ \^ \& \_ \{ \}}) are escaped by a
      \typ{\\} 
    \item \typ{\\} symbol is inserted using \typ{\\textbackslash}
      command
    %\item \textbackslash newline or \textbackslash \textbackslash\ is used to insert newlines.
    \item \typ{\\newline} or \typ{\\\\} is used to insert newlines.
  \end{itemize}
\end{frame}

\frametitle{Self assessment questions}
\label{sec-9}
\begin{enumerate}
  \item Convert the temp.dvi created during the course of this tutorial to temp\_1.ps using the dvips command. Verify that the two files indeed look the same.
  \vspace{8pt}
  \item Convert the temp.dvi created during the course of this tutorial to temp\_1.pdf using the dvipdfm command. Verify that the two files indeed look the same.
\end{enumerate}

\frametitle{Solutions}
\label{sec-10}
\begin{enumerate}
  \item We can use the following command to convert temp.dvi to temp\_1.ps\\
    \begin{block}{}
      \begin{center}
        dvips -o temp\_1.ps temp.dvi
      \end{center}
    \end{block}
  \vspace{15pt}
  \item We can use the following command to convert temp.dvi to temp\_1.pdf\\
    \begin{block}{}
      \begin{center}
         dvipdfm -o temp\_1.pdf temp.dvi
      \end{center}
