So I take it you don't want it to work, even if you enter a function.
In other words, if the user enters "cos(x)", then it won't use the
cosine function.
Unfortunately, it's currently hardwired into the parser, i.e., on line
148 of sympy/parsing/sympy_parser.py:
global_dict = {}
exec 'from sympy import *' in global_dict
You could fix it by removing these lines. Really, it should let you
manually set the global_dict, just as you can set the local dict.
I created http://code.google.com/p/sympy/issues/detail?id=2947 for this.
