Thanks Han. I suppose purge() should have been obvious to me. But it wasn't.

Example, to define -pi < s < pi:

assume(s>-pi)
additionally(s<pi)
about(s)

Thanks Mark, especially the simple but clear example that explains it all. After posting, I realized I forgot to include the question on how to see the current assumptions, and you even answered that as well.

Very helpful replies guys, thanks!
