Raise your hand if you think the only solutions to sin(x) = 0.5 are 30 degrees or pi/6 radians. Feel free to use your calculator. If you raised your hand, promptly use your hand to download this application. There are actually an infinite number of solutions to most inverse trigonometry problems, but your calculator probably only gave you one. Guess what.
