I'm not sure if homework questions are allowed on here (and please disregard me if they aren't, I'm having a freak attack... internet berations won't make me any better a mathematician).

So... why is

sin((pi/2)+x) = cosx?



EDIT: Nevermind, found answer. Calculator was on wrong setting. Forgive me!
