Tracy Huesso: Keep adding or subtracting π until you have a result whose absolute value is less than or equal to π/2 (0.5π). The absolute value will be the reference angle.a) Reference angle = 2.1π-2π = 0.1πb) Assume the 2.1 is measured in radians. Since π/2 ≈ 1.571 and π ≈ 3.142Reference angle = |2.1-3.142| = 1.042 radiansc) Reference angle = -10π + 10π = 0...Show more
