Comment #3 on issue 1088 by ness...@googlemail.com: integrate(log(x)*exp(x), (x, 0, oo)) should return -EulerGamma
http://code.google.com/p/sympy/issues/detail?id=1088
the original integral of this issue does not even exist. Maybe exp(-x) was meant instead? in gsoc-3:
In [90]: integrate(log(x)*exp(-x), (x, 0, oo)) Out[90]: -EulerGamma -- You received this message because you are subscribed to the Google Groups "sympy-issues" group.
