I'd think that Maxima should do range reductions like?cos(23/5*%pi) => cos(3/5*%pi) by default, and even for that matter?cos

You should clarify what what you intend for negative angels:
cos(-23/5*%pi) => cos(2/5*%pi) ???
While this isn't a very problematic issue, it ought be specified. cos
is symmetric about zero, but this property is more evident if the domain
were reduced to -pi..+pi instead. Would this matter anywhere?
