Math into Latex
Your Latex
Editing Cycle
A text editor is used to create a source file
“Typesets” the source file and views the result on the monitor
Making changes and observing the results of these changes
Print the file and mostly creates a PDF file of the typeset version
Three productivity tools
Synchronization
move quickly between the source file and the typeset file
Block comment
comment or uncomment a block of text at one time
Jump to a line
jump to a line specified in the source file by the line number
Typing text
A source file
text
math (formulas)
instructions (commands) to LaTeX
command with an argument
command without an argument
environment.
content: the text that is typed between two environment commands
start with a backslash ( \ )
The keyboard
used to type text
a-z A-Z 0-9 + = * / ( ) [ ]
punctuation marks can be used
, ; . ? ! : ` ' -
the space bar, the Tab key, and the Return (or Enter) key
special keys used in LaTeX commands
# $ % & ~ _ ^ \ { } @ " |
Only @ requires no special command
Others need to insert a backslash ( \ ) before
Your first note
comments
everything on the line after % is ignored
document class
control how the document is formatted
environment
\begin{document} and \end{document}
text
typed within the document environment
Lines too wide
LaTeX uses points (pt) to measure distances
hyphenate a hyphenated word only at the hyphen
LaTeX’s standard hyphenation routine cannot handle German hyphenation and so on
More text features
display the date on which the document is typeset
\today
environments to justify text
\begin{flushright} ... \end{flushright}
\begin{center} ... \end{center}
\begin{flushleft} ... \end{flushleft}
text style
\emph
emphasize text
\textbf
bold text
\texttt
typewriter style text
form of the LaTeX commands
backslash( \ )
command name
terminated by the first nonalphabetic character
case sensitive
arguments (if have)
takes the next character as argument if braces non-exist
multiple role of hyphens
Double hyphens are used for number ranges
89--64 as 89-64
triple hyphens for the em dash punctuation mark
--- as —
new line command
\\ (or \newline):
create additional space between lines
\\[distance]
square brackets means optional
distance may be given in points (pt), centimeters (cm), or inches (in)
new page command
\newpage
Special rules for special characters
accented characters and some European characters
e.g. \"{a}
Typing math
math environments
inline
open and close with $
displayed
open with \[ and close with \]
spacing rules
ignore space with two exceptions
spaces terminate commands
Spaces in the arguments of certain commands
e.g. /text
formula
Arithmetic
\cdot or \times
. or x in ab as a.b or a x b
\frac
for fractions and seldom used inline
(underscore)_ and (caret)^
subscript and superscript
should be enclosed in braces or take the first one as argument
(prime)'
automatically superscripted in math
Binomial coefficients
\binom{}{}
Congruences
a \equiv v \pmod{\theta}
Topic
a \equiv v \pod{\theta}
Topic
Delimiters
\left and \right
resize the parentheses according to the symbols inside
\quad
a spacing command
Ellipses
\dots
ellipsis ( . . . ) in text
Integrals
\int
an integral
The lower limit is specified as a subscript
the upper limit is specified as a superscript
\,
a spacing command
Math accents
\bar{a}
\hat{a}
\tilde{a}
\vec{a}
Matrices
\begin{matrix} ... \end{matrix}
matrix environment
has to appear within a math environment
As a rule, it's in a displayed math environment
does not provide delimiters
&
separate matrix elements within a row
\\
separate rows
Do not end the last row with a new line command
\begin{pmatrix} ... \end{pmatrix} \begin{vmatrix} ... \end{vmatrix}
provide delimiters as \left( ... \right) \left| ... \right|
Operators
\sin
\lim_{x \to 0} f(x) = 0
Large operators
\sum
for sum
\sum_{i=1}^{n} x_{i}^{2}
\prod
for product
\prod_{i=1}^{n} x_{i}^{2}
Roots
\sqrt
\sqrt{a + 2b}
\sqrt[n]{5}
Text
\text
Displayed formulas
Equations
\begin{equation} ... \end{equation}
the equation number is automatically generated
use symbolic label to refer to the equation
the argument of the \label command
used the convention that the label of an equation starts with E:
referenced
\ref
the number of the formula
\eqref
provide the reference number in parentheses
\pageref
the page of the formula
~
nonbreakable space
ensure the equation number on the same line
symbolic referencing
symbol
the argument of the \label command
can be referenced with \ref, \eqref, or \pageref commands
same mechanism for all of the generated numbering systems
sections, subsections, subsubsections, equations, theorems, lemmas, and bibliographic references
except that for bibliographic references
\bibitem
define a bibliographic item and
\cite
cite a bibliographic item
tagged
\tag
The tag replaces the equation number
Tags are absolute while numbers relative
\notag
prevent the numbering
useful in a fromula more than one line
Aligned formulas
\begin{align} ... \end{align}
Simple alignments
\\
line separator
should not have one to terminate the last line
&
alignment point
place it before where you want to be aligned
Annotated alignment
&&
a mark for the start of the annotation
align* environment
no line be numbered
cases
within a math environment such as equation or align environment
\begin{cases} ... \end{cases}
you can put inline math inside the argument of a \text command
\\
Separate the lines
&
indicate the annotation
first article
The anatomy of an article
preamble
everything from the first line to the line \begin{document}
specify additional commands that are used throughout the document
specifies the document class and enhancements or packages
\documentclass
The only required command
\usepackage{}
\newtheorem{}{}
body.
the content of the document environment
between the lines \begin{document} and \end{document}
top matter
title page information and the abstract
follows the line \begin{document} and concludes with the line \maketitle
main matter
\section{}
\begin{theorem} ... \end{theorem}
\begin{figure}[hbt] \centering\includegraphics{} \caption{} \end{figure}
\begin{proof} ... \end{proof}
back matter
\begin{thebibliography}{n} \bibitem{maker} content bibitem{}... \end{thebibliography}
n tell LaTeX to make room for number 9 for references fewer than 10 99 for references between 10 and 99 and so on
reference with the \cite{marker} command
An article template
Top matter
\thanks
places an unmarked footnote at the bottom of the first page
\author
multiple authors get separate \author and \address commands
\address
Separate the lines with \\
Do not put a \\ at the end of the last line
\date
\date{\today} typesets today’s date
\date{March 14, 2009}
\title
the only required command
break the title into separate lines with \\ Do not put a \\ at the end of the last line
\maketitle
if you do not give the \maketitle command, even the \title command is optional On the other hands, if there exists \maketitle and no \title, there comes an error
Sectioning
\section{Content}\label{mark} ... \ref{mark}
section number is automatically assigned
\section* produces an unnumbered section
\subsection \subsubsection \subsection* \subsubsection*
proclamations
defined in the preamble with \newtheorem
theorem number is automatically assigned
\begin{theorem}\label{mark} Content \end{theorem} ...ref{mark}
references

You have to arrange the references in thebibliography environment to see them LATEX only takes care of the numbering and the citations in the text
On using LaTeX
error messages
Typographical errors
errors in mathematical formulas or in the formatting of the text
errors in your instructions to LaTeX
Tip Typeset often
Logical and visual design
you should concentrate on what you say let LaTeX take care of the visual design
