Dear Patrick, In my recent answer to you I forgot to give you an example of a limit involving x Log[f(x)] for which the result is not 0. Here it is, presented with Mathematica : In[1]:= Limit[ x^(1/x), x->0] Out[1]= 0 In[2]:= Limit[ x Log[x^(1/x)], x->0] Out[2]= -Infinity Hope it helps, Olivier At 06:05 +0200 97.10.08, Patrick Tao wrote: > Hello mma users, > > I have a quick question on the following computation: > > the natural log of 0 times 0 writen Log[0]*0 > > > > Should that not be 0 ? > > mma is returning an Indeterminate result > > Can somebody please help me understand this computation. > > > > Many Thanks > > -patrick
