Evaluate the following expressions. Your answer must be an angle -T/2 ≤0 ≤ in radians, written as a multiple of T. Note that is already provided in the answer so you simply have to fill in the appropriate multiple. E.g. if the answer is π/2 you should enter 1/2. Do not use decimal answers. Write the answer as a fraction or integer. sin ¹(sin((-77/4)) = sin ¹(sin(77/6))= cos-¹(cos(5π/4))= cos ¹(cos(5/3))= π R π T
