1 Introduction
TEX looks more difficult than it is. It is
almost as easy as
p. See how easy it is to make special
symbols such as
a,
b,
g,
d,
sinx,
ℏ,
l,
… We also can make
subscripts
Ax,
Axy and superscripts,
ex,
ex2, and
eab.
We will use
LATEX, which is based on
TEX and has
many higher-level commands (macros) for formatting, making
tables, etc. More information can be found in Ref
.[1].
We just made a new paragraph. Extra lines and spaces make no
difference. Note that all formulas are enclosed by
$ and occur in math mode.
The default font is Computer Modern. It includes italics,
boldface,
\textslslanted, and monospaced fonts.
2 Equations
Let us see how easy it is to write equations.
D= Si=1Nwi (xi - x̄)2 .

It is a good idea to number equations, but we can have a
equation without a number by writing
and
We can give an equation a label so that we can refer to it later.
E = -J Si=1Nsi si+1 ,

Equatio
n2 expresses the energy of a configuration
of spins in the Ising model.

We can define our own macros to save typing. For example, suppose
that we introduce the macros:
\newcommand\lb\langle
\newcommand\rb\rangle
Then we can write the average value of x as
The result is
