Just to check, do you get symbolic arguments working OK? e.g.
integrate(cos(x), (x,0,1))

As per http://code.google.com/p/sympy/issues/detail?id=2656 , the sympy
function (if one is available) would need to supersede the mpmath function,
or catch exceptions, for symbolic manipulations to be handled. If the
inclusion into the argument dictionary in Dynamic is reversed (see
D.rebuild_globals) this would work, but is there a numerical reason that
the mpmath library is preferred when functions are available in both? Or
does it improve compatibility and consistency with the other mpmath
functions? I'm afraid I'm a bit vague on the sympy core/mpmath differences
:s
