I have the following SVG: http://bensouthgate.com/i/malthus2.svg
Which shows b(y) = d(y)
However, when I embed it in a page: http://bensouthgate.com/p/malthus.php
it shows b(y) = f(y)
among other mistakes.
The way I am including it in the page is
<?php include '../i/malthus2.svg'; ?>
What is going on?
Edit: SVG was rendered here -> http://www.tlhiv.org/ltxpreview/
