This question is the very end of a large problem that I really can't figure out. It's an online course and the computer keeps saying the same thing so I am getting confused. It says simplify 1-(1-sinθ) My answer: -sinθ Computer's answer: sinθ From what I understand, it would come out to -sinθ but the computer keeps saying its positive sinθ. I know I am probably overlooking something and that is why I am asking here for advice. I am just trying to understand what I am missing.
