New issue 2192 by [email protected]: limit is getting an order term from exponential
http://code.google.com/p/sympy/issues/detail?id=2192

The following series fails because limit was given a series by exponential that contained an order term. Either limit should remove order terms or the calling routine should not send them. I've removed the order term in the calling routine and added a commit solving this to branch 2084 ( pull/61 ).


    exp(sin(x)*log(x)).series(n=2) == 1 + x*log(x) + O(x**2)

It used to give

  File "sympy\series\gruntz.py", line 235, in mrv
raise NotImplementedError("Don't know how to calculate the mrv of '%s'" % e)

NotImplementedError: Don't know how to calculate the mrv of 'O(log(_p)/_p**6)'

The result above was checked against wolfram alpha.
