1. The problem statement, all variables and given/known data State an equivalent expression in terms of the related acute angle? (A) cot(-π/4) 2. Relevant equations 3. The attempt at a solution (A) I made the the unit circle and since its negative I went clockwise and made it into the fourth quadrant. I ended up getting -cotπ/4. However the answer is not the one that the text book has given. Im a little confused. The text book has given the answer cot3π/4, but I thought we were supposed to go clockwise because it is negative?
