Sorry if this is not the correct forum to report a possible bug.
I noticed browsing the "Example of second-order singular perturbation
theory" section of the "Perturbation Theory" page on wikipedia:
---
Consider the following equation for the unknown variable <math>x</math>:
:<math>x=1+\epsilon x^5.</math>
For the initial problem with <math>\epsilon=0</math>, the solution is
<math>x_0=1</math>. For small <math>\epsilon</math> the lowest
order
approximation may be found by inserting the [[ansatz]]
:<math>x=x_0+\epsilon x_1 (+\cdots)</math>
--
that the markup fonts of "x" in each of the :<math> sections are
different.
In particular there are no serifs on the top x's in the first equation and
x_0=1 on my Linux box. On the others, there are small serifs.
I don't see why they should be rendering differently. The ascii certainly
doesn't indicate anything to me...
I've tested this on:
IE7.0 Windows
Safari 4.0 on OSX 10.5
Firefox 3.5 on OSX 10.5
Firefox 3.0.10 on Linux 2.6.18-128.1.10.el5
I've attached a small screenshot of what I see.
