Webb4 aug. 2016 · Explanation: θ = tan−1(tan( 5π 6)) by definition satisfies both of the conditions: Xtanθ = tan( 5π 6) X − π 2 < θ < π 2. Note that tan has period π, so for any integer n: tan( 5π 6 + nπ) = tan( 5π 6) When n = −1, we have: 5π 6 + nπ = 5π 6 − π = − π 6. which lies in the range ( − π 2, π 2), so satisfies the second ...
