Introduction to LaTeX A Mathematical typesetting system
The very first line! The very last line! The “Required” ElementsAll LaTeX documents must include the following parts: \documentclass[12pt]{article} \begin{document} \end{document} The “PREAMBLE” goes here The BODY of the document goes here
“Environments” • LaTeX code is set up with “environments.” Everything is enclosed in the “document” environment. \begin{document} \end{document} The document environment
“Environments” You enter and leave most environments with beginning and ending commands of the form \begin{environmentname} \end{environmentname} The code/text goes here
Some Formatting environments \begin{center} . . . \end{center} Numbered lists \begin{enumerate} \item \item \end{enumerate} The first item in the numbered list goes here The second item in the numbered list goes here
More on enumeration If you want “sub-headings,” nest the lists \begin{enumerate} \item \begin{enumerate} \item \item \end{enumerate} \item \end{enumerate} The first item in the sub-list goes here The second item in the sub-list goes here
More on lists If you want “bulleted” lists, you use the same format as for numbered lists with \begin{itemize} \item \begin{itemize} \item \item \end{itemize} \item \end{itemize}
More on lists If you want to designate the “headings” for the lists, you use the description environment \begin{description} \item[Case i.] \item[Case ii.] \end{description} The text for Case i. goes here The text for Case ii. goes here
Typesetting Mathematics There are two main math environments • In-line math mode. This is for equations that occur in the same line as narrative. You enter and leave in-line math mode with dollar signs. Ex: $f(x)=x^{3-x}$ • Displayed math. Several entry/exit choices • \begin{displaymath} . . . \end{displaymath} • $$ . . . $$ • \[ . . . \]
“Normal” text How many subsets does have? LaTeX code How many subsets does $\emptyset$ have? Some Miscellaneous Expressions Notice the use of the backslash ( \ ). This is your message to LaTeX that you are about to give it a command.
“Normal” text How many subsets does have? LaTeX code How many subsets does $\emptyset$ have? $A=\{ 1,2,3,4\}$ $A \subseteq B$ and $B \subseteq A$. $$ f(x)=\frac{x^3}{1+x^2}.$$ Some Miscellaneous Expressions
