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

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