I am confused.
many times, I want to find if there is a way to obtain one expression
from another by tranformation.
for example, we know that 1-sin^2(x) = cos^2(x), and a*log(x)=log(x^a),
etc.., but sometimes this does not seem to work using SameQ:
SameQ[a Log[x], Log[x^a] ]
I tried MatchQ and that also gives False.
what is the right way to do these things in Mathematica? I checked the on-line help,
and can't seem to see the right command for this.
