Find the Reference Angle (17pi)/6

Problem

(17*π)/6

Solution

1. Find the coterminal angle within the range [0,2*π) by subtracting multiples of 2*π

(17*π)/6−2*π=(17*π)/6−(12*π)/6

(17*π)/6−(12*π)/6=(5*π)/6

2. Identify the quadrant where the angle (5*π)/6 terminates. Since π/2<(5*π)/6<π the angle is in Quadrant II.

3. Apply the reference angle formula for Quadrant II, which is θ′=π−θ

θ′=π−(5*π)/6

4. Simplify the expression to find the final reference angle.

θ′=(6*π)/6−(5*π)/6=π/6

Final Answer

Reference Angle of (17*π)/6=π/6
