# Extension talk:TrustedMath

Works also under MediaWiki 1.19

For more functions as mathfrak, you can change your file TrustedMath_body.php and add more package like :

protected static function wrapEquation( $equation ) { return implode( "\n", array( '\documentclass{article}', '\pagestyle{empty}', '\usepackage{amsfonts}', '\usepackage{amsmath}', '\usepackage{amssymb}', '\usepackage{amsthm}', '\usepackage[usenames]{color}', '\usepackage[usenames,dvipsnames]{xcolor}', '\usepackage{engrec}', '\begin{document}', '\begin{equation*}', trim($equation ),
'\end{equation*}',
'\end{document}',
) );
}

and with that, you will be able to use all the formula of the page : http://meta.wikimedia.org/wiki/Help:Formula

## Error while using TrustedMath

I've installed MikTeX as mentioned in the instructions and have provided path to the latex.exe and dvipng.exe files. However I am seeing a weird problem while using the extension. I am using the unsafe mode right now:

when i try to render the Riemann Zeta example the extension manages to do it flawlessly. This works: ${\displaystyle \zeta (s)=\sum _{n=1}^{\infty }n^{-s}={\frac {1}{1^{s}}}+{\frac {1}{2^{s}}}+{\frac {1}{3^{s}}}+\cdots \;\;\;\;\;\;\;\sigma =R(s)>1.\!}$

So does this: ${\displaystyle \zeta ,\alpha }$

So does this: ${\displaystyle F_{n}=(I_{n-1}+T_{n-1})*SIF_{n}}$

However, this does not: ${\displaystyle \zeta ,\alpha F_{n}=(I_{n-1}+T_{n-1})*SIF_{n}}$

And instead gives me the following error:
