Topic on Extension talk:Math

I am not clear what i need in Localsettings.php. I have texvc working as I run the test as per the read me with

texvc /home/wiki/tmp /home/wiki/math "y=x+2" iso-8859-1 "rgb 1.0 1.0 1.0"

(although not wit exact path as above) and that produce the png file as expected

LocalSettings.php

$wgShowExceptionDetails = true;

wfLoadExtension( 'Math' );

$wgDefaultUserOptions['math'] = 'mathml';

$wgMathFullRestbaseURL= 'https://api.formulasearchengine.com/';
