LaTeX "\indent" creating paragraph indentation / tabbing package requirement?

The LaTeX code provided below shows the usage of the command \indent as it appears in the document, but it does not produce the desired indentation within the document. Is there a specific package associated with the command \indent or \=? I´m asking for a step by step method of开发者_JAVA技巧 producing an indentation within a document for only one paragraph, regardless of location within the document.

\documentclass[12pt]{article}

\usepackage{graphicx}

\topmargin -3.5cm

\oddsidemargin -0.04cm

\evensidemargin -0.04cm

\textwidth 16.59cm

\textheight 21.94cm

\parskip 7.2pt

\parindent 8pt

\title{Physics}

\author{Pareshkumar Brahmbhatt}

\begin{document}

\maketitle

\indent Now we are engaged in a great civil war.

\end{document}

LaTeX will usually not indent the first paragraph of a section. This is standard typographical practice. However, if you really want to override this default setting, use the package indentfirst available on CTAN.

The first line of a paragraph is indented by default, thus whether or not you have \indent there won't make a difference. \indent and \noindent can be used to override default behavior. You can see this by replacing your line with the following:

Now we are engaged in a great civil war.\\
\indent this is indented\\
this isn't indented


\noindent override default indentation (not indented)\\

This is kind of a hack but the best solution that I have found is to use a description tag with no \item. This will produce an error from the latex compiler; however, the error does not prevent the pdf from being generated.

\begin{description} 
     <YOUR TEXT HERE> 
\end{description}
