C

#### cdot (multiplication)

$$a\cdot~b$$ gives $a\cdot~b$

#### chi (lower case greek letter)

$$\chi$$ gives $\chi$

#### constants

• Numbers in formulas are interpreted as constants and they are rendered in non-italic roman font face, which is a widely used convention.
• Following this convention, variables are shown in italic.
• Exp.: $$f(x)=3a+x$$ gives

$f(x)=3a+x$

#### 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

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

• Use font size commands for a nicer picture:

$$\LARGE\bigcoprod_{\small{i=k}}^{\small~n}$$   gives

$\LARGE\bigcoprod_{\small{i=k}}^{\small~n}$
