In pages 239 and 241 of the additional material that you gave us, the author talks about the "active view" and "passive view." What are they?

Also in page 242, what is an "ansatz"?

"Active view" is when you rotate the system keeping the reference frame fixed, "passive view" is when you keep the system fixed but you rotate the reference frame in opposite direction.

An "ansatz" is a guess that you assume to be true and try it in an equation. It's a german word meaning "basis" or "starting point".  coolsmiley
