I get no such error -- there simply seems to be no explicit form for the indefinite integral. In[1]:= {$System, $Version} Out[1]= {"Microsoft Windows","Microsoft Windows 3.0 (October 6, 1996)"} In[2]:= Integrate[Exp[x]/Log[x],x] Out[2]= Integrate[E^x/Log[x], x] Quoting form The Book,(1.5.3),"this integral simply cannot be done in terms of standard mathematical functions. As a result, Mathematica just leaves it undone." Tomas Garza Mexico City
