Every once in a while, I’ll cover a theorem in class that looks utterly surprising to students at first glance. For example, in trigonometry, I might state that
,
so that the inverse function doesn’t quite behave like it’s supposed to (because of the restricted domain used to define inverse sine.)
Before explaining why isn’t equal to
