This is indeed mysterious and somewhat worrying but still one can deal with it (though admittedly one would not want to have to do this sort of thing very often): In[78]:= FullSimplify[(Sqrt[2] x/2)^2 Sin[x/2]^2, ComplexityFunction -> (Count[{#}, _Sin, Infinity] &)] Out[78]= 1 2 -(-) x (-1 + Cos[x]) 4 -- Andrzej Kozlowski Toyama International University JAPAN http://sigma.tuins.ac.jp http://eri2.tuins.ac.jp ---------- >From: Leszek Sczaniecki <leszek2 at home.com> >To: mathgroup at smc.vnet.net >Subject: [mg19888] [mg19877] Re: [mg19811] Re: [mg19765] Re: [mg19677] Mathematica can't win against Tiger Woods >Date: Sun, Sep 19, 1999, 2:20 PM > > Or perhaps, for what > technical reason it can do this simplification > > In[1]:= FullSimplify[(Sqrt[2] 1/2))^2 Sin[x/2]^2] > > Out[1]= > 1/4 (1 - Cos[x]) > > but fails here > > In[2]:= FullSimplify[(Sqrt[2] x/2))^2 Sin[x/2]^2] > > Out[2]= > 1/2 x^2 Sin[x/2]^2 > ?
