Final answer:
The reference angle for θ = 11π/6 is calculated by subtracting the angle from 2π, resulting in π/6 radians as the reference angle.
Step-by-step explanation:
To calculate the reference angle for θ equals 11π over 6, you need to understand that the reference angle is the acute angle that the given angle makes with the x-axis. Since 11π/6 radians is just shy of 2π (or a full circle), which is equivalent to 360 degrees, the reference angle is found by subtracting this angle from 2π.
The correct computation for the reference angle of θ = 11π/6 is therefore:
2π - (11π/6)
Simplifying this expression:
12π/6 - 11π/6 = π/6
Thus, the reference angle is π/6 radians.
