WebDec 20, 2024 · a) On the unit circle, the angle θ = 2π 3 corresponds to the point ( − 1 2, √3 2). Therefore, sin ( 2π 3) = y = √3 2. b) An angle θ = − 5π 6 corresponds to a revolution in the negative direction, as shown. Therefore, cos( − 5π 6)=x=− √3 2. c) An angle θ = 15π 4 = 2π + 7π 4. Therefore, this angle corresponds to more than one revolution, as shown.
