Using the option Direction (limit from below/above) solves the problem: In[6]:= Limit[Abs[Sin[x] - Sin[2*x]]/x, x -> 0, Direction -> 1] Out[6]= -1 In[5]:= Limit[Abs[Sin[x] - Sin[2*x]]/x, x -> 0, Direction -> -1] Out[5]= 1 Wolfgang Amir wrote: > Hi, > > I'd like to find the limit of > Limit[(Abs[Sin[x]-Sin[2 x]]) / x, x->0] > > I use Mathematica v.5.
