Summary: no exact result sin(%pi/12)

Initial Comment:
Maxima doesn't count exact result of sin(%pi/12) or cos(%pi/12), etc. despite the fact it's simple. It is (sqrt(3)-1)/2*sqrt(2) - or (in other form): (sqrt(6)-sqrt(2))/4.

Message:
This is really a feature request, not a bug.

Having said that, I have some code to handle this and other cases like
%pi/3/2^m and %pi/5/2^m.
