05 SPACES

\hspace{n}

inserts a space of n pixels
Ex.: $$f(x)\hspace{6}=\hspace{6}0$$ gives $f(x)\hspace{6}=\hspace{6}0$
can be combined with the preceding command \unitlength{m}(default: m=1px) , which defines the applied unit
Ex.: $$\unitlength{20}a\hspace{2}b$$ gives $\unitlength{20}a\hspace{2}b$ , i.e. a space of 20x2=40px

Keyword(s):

\qquad

inserts a double space of current character set size
Ex.: $$a\qquad~b$$ gives $a\qquad~b$

Keyword(s):

\quad

inserts a space of current character set size
Ex.: $$a\quad~b$$ gives $a\quad~b$

math spaces

List of predefined spaces:

Math Spaces
Command	Example	Result
\, (smallest predefined)	$$a\,b$$	$a\,b$
\: (second smallest predefined)	$$a\:b$$	$a\:b$
\; (third smallest predefined)	$$a\;b$$	$a\;b$
\/ (avoiding ligatures)	$$V\/A$$ instead of $$VA$$	$V\/A$ instead of $VA$
\quad (space of current character set size)	$$a\quad~b$$	$a\quad~b$
\qquad (double space of current character set size)	$$a\qquad~b$$	$a\qquad~b$
\_ (where _ is blank!)	$$a\ b$$ (whereas $$a\b$$ is not a valid filter expression since the blank space is missing; it is recommended to use the tilde ~ instead of the simple whitespace)	$a\ b$
\hspace{n} ,where n positive integer (= n Pixels)	$$a~\hspace{30}~b$$ $$a~\hspace{15}~b$$ $$a~\hspace{2}~b$$ $$a~\hspace{1}~b$$	$a~\hspace{30}~b$ $a~\hspace{15}~b$ $a~\hspace{2}~b$ $a~\hspace{1}~b$
\unitlength{m}\hspace{n}, changes the default unit length (m=1px) to be applied	$$a~\hspace{2}~b\unitlength{10}~\hspace{2}~c$$ (second space is 10x2=20px)	$a~\hspace{2}~b\unitlength{10}~\hspace{2}~c$

Note: Simple blank spaces and tildes (~) are ignored by the TeX filter and don't produce any space. You must use one of the defined math spaces to get a visible (extra) space.

$$\alpha$$ gives

$\alpha$

contour integral

General syntax for symbols with a kind of lower and upper limits:

\symbolname_{lowerexpression}^{upperexpression}

In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
Syntax for the contour integral symbol:

$$\bigoint_{0}^{\infty}$$ gives

$\bigoint_{0}^{\infty}$

and

$$\oint_{0}^{\infty}$$ gives

$\oint_{0}^{\infty}$

Use font size commands for a nicer picture:

$$\LARGE\bigoint_{\small0}^{\small\infty}$$ gives

$\LARGE\bigoint_{\small0}^{\small\infty}$

and

$$\large\oint_{\small0}^{\small\infty}$$ gives

$\large\oint_{\small0}^{\small\infty}$

coproduct

General syntax for symbols with a kind of lower and upper limits:

\symbolname_{lowerexpression}^{upperexpression}

In general, there are two ways how these lower and upper expressions can be placed: centered below and above the symbol or in a subscript / superscript manner. In the first case the symbol name is preceded by the word "big", in the second there is no prefix.
Note: mimeTeX seems currently only to support the \bigcoprod command.
Syntax for coproduct symbol:

$$\bigcoprod_{i=k}^{n}$$ gives

$\bigcoprod_{i=k}^{n}$
