BetaRegularized[q,2,2] is (3-2q)q^2, which is zero only at q=0 and
q=2/3.
So why does Mma 3.0 (Windows 95) give me this:
In[21]:= Clear[q]
In[22]:= FullSimplify[BetaRegularized[q,2,2]]
Out[22]= 0
even though Mma knows it is not zero:
In[23]:= N[BetaRegularized[1/2,2,2]]
Out[23]= 0.5
This kind of crap drives me nuts!
