Simple Math Formulae in Wikka
This is, I'll readily admit, almost a direct steal from Wikini. It uses a rendering engine to convert simple math scripts to images. For details on syntax see http://wiki.algebra.com/index.php/Formula_plotting_feature_guide
Note that for multi-line actions to work you must modify wikka.php as per the instructions at TableAction (thanks JavaWoman, or I'd never have gotten this working).
Place the following code as a file actions/math.php
<?php
/*
titre: Action Math pour Wikini

License: GPL
slightly modified by GmBowen for Wikka
example: {{math expression="x^2/sqrt(sin(x))"}}
*/
$baseurl = "http://www.algebra.com/cgi-bin/plot-formula.mpl?expression=";
$fullurl = $baseurl . rawurlencode($expression);
echo "<img src=\"$fullurl\" alt=\"expression math\" valign=\"middle\"/>";
?>

$baseurl = "http://www.algebra.com/cgi-bin/plot-formula.mpl?expression=";
$fullurl = $baseurl . rawurlencode($expression);

?>
examples of actions that can be implemented in wikka are:
%%
Unknown action ""math""
Unknown action ""math""
Unknown action ""math""
Unknown action ""math""
Unknown action ""math""
Unknown action; the action name must not contain special characters.
{{math expression="(
matrix( 2, 3,
x, y,
x/2, y 3
