Find the Reference Angle pi/3

Problem

π/3

Solution

1. Identify the quadrant in which the given angle θ=π/3 lies.

2. Determine that since 0<π/3<π/2 the angle is located in the first quadrant.

3. Apply the rule for reference angles in the first quadrant, which states that the reference angle θ′ is equal to the angle itself: θ′=θ

4. Conclude that the reference angle is π/3

Final Answer

θ′=π/3
