Comment(by kcrisman):

 Even weirder, for a second it did work on 4.1.2.alpha1 for me.  Then I
 exited and started again, and it went back to this weird behavior.

 Anyway, the problem is probably that we fixed something a while ago to
 catch constant function plotting, and 1+x-x evaluates to 1 in Sage, but
 the trig identity doesn't.
