1. It works in Mathematica 3.0 in a Sun SPARCcenter-2000 running SunOS
5.5. Watch:

In[1]:= Limit[Log[x]/(x-1)^3,x->0,Direction->-1]

Out[1]= \[Infinity]

2. You don't need to take this limit, as the denominator is not doing
anything strange as x->0. Watch:

In[11]:= (x-1)^3 /. x->0

Out[11]= -1

Regards,
David.
