I'm not sure what you have in mind, but scsimp is supposed
to simplify by applying side-conditions. ratsimp does not. They
do different things.
scsimp(s^2+c^2, s^2+c^2-1) produces 1.
As far as I can tell, scsimp is a heuristic program that
tries to do what would be done by a sequence of substitutions.
These might be better done by ratsubst, or even by grobner
basis reductions.
