I am a bit perplexed by the following behavior of Mathematica:
( 6:22PM) bombay[~]% math
Mathematica 4.2 for Linux

In[1]:= Gamma'[1/2]
1
Out[1]= Sqrt[Pi] PolyGamma[0, -]
2
In[2]:= FullSimplify[%]
1
Out[2]= Sqrt[Pi] PolyGamma[0, -]
2
In[3]:= FunctionExpand[%]
Out[3]= Sqrt[Pi] (-EulerGamma - Log[4])
According to the FunctionExpand help, it is automatically called by
FullSimplify. Why am I not getting Out[3] after the FullSimplify?
Certainly it is "simpler" than Out[2].
