Math Formulae ::(::)::[::]::$::
############################################################

There are three environments that put LaTeX in math mode: 
	math		For Formulae that appear right in the text. 
	displaymath	For Formulae that appear on their own line. 
	equation	The same as the displaymath environment 
			except that it adds an equation number in 
			the right margin. 
The math environment can be used in both paragraph and LR mode, 
but the displaymath and equation environments can be used only 
in paragraph mode. The math and displaymath environments are 
used so often that they have the following short forms:
 
	\(...\)	instead of	\begin{math}...\end{math}

	\[...\]	instead of	\begin{displaymath}...\end{displaymath}

In fact, the math environment is so common that it has an even 
shorter form: 

	$ ... $	instead of	\(...\)

	Subscripts & Superscripts: Also known as exponent or index. 
	Math Symbols: Various mathematical squiggles. 
	Spacing in Math Mode: Thick, medium, thin and negative spaces. 
	Math Miscellany: Stuff that doesn't fit anywhere else. 

############################################################
	Subscripts & Superscripts ::_::^::
############################################################
To get an expression exp to appear as a subscript, you just 
type _{exp}. To get exp to appear as a superscript, you type 
^{exp}. LaTeX handles superscripted superscripts and all of 
that stuff in the natural way. It even does the right 
thing when something has both a subscript and a superscript. 
############################################################
	Math Symbols
############################################################
LaTeX provides almost any mathematical symbol you're likely 
to need. The commands for generating them can be used only in 
math mode. For example, if you include $\pi$ in your source, 
you will get the symbol in your output. 
############################################################
	Spacing in Math Mode
############################################################
In a math environment, LaTeX ignores the spaces you type and 
puts in the spacing that it thinks is best. LaTeX formats 
mathematics the way it's done in mathematics texts. If you 
want different spacing, LaTeX provides the following four 
commands for use in math mode: 

	\; - a thick space ::;::
	\: - a medium space :::::
	\, - a thin space ::,::
	\! - a negative thin space ::!::

############################################################
	Math Miscellany
############################################################
	\cdots ::cdots::
Produces a horizontal ellipsis where the dots are raised to 
the centre of the line. eg. 
	\ddots ::ddots::
Produces a diagonal ellipsis. eg. 
	\frac{num}{den} ::frac::
Produces the fraction num divided by den. eg. 
	\ldots ::ldots::
Produces an ellipsis. This command works in any mode, not 
just math mode.  eg. 
	\overbrace{text} ::overbrace::
Generates a brace over text. eg. 
	\overline{text} ::overline::
Causes the argument text to be overlined. eg. 
	\sqrt[root]{arg} ::sqrt::
Produces the square root of its argument. The optional argument, 
root, determines what root to produce, i.e., the cube root 
of x+y would be typed 
as $\sqrt[3]{x+y}$. eg. 
	\underbrace{text} ::underbrace:: 
Generates text with a brace underneath. eg. 
	\underline{text} ::underline::
Causes the argument text to be underlined. This command can 
also be used in paragraph and LR modes. eg. 
	\vdots ::vdots::
Produces a vertical ellipsis. eg.
