I was going to check if this also fixed the dot on the 'i' in sin as
well as the equals sign, but I get the following:

  File "/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/mathtext.py", line 616, in _get_info
    raise ValueError('unrecognized symbol "%s"' % sym)
ValueError: unrecognized symbol "\sin"
