Question

How do you find the reference angle for 13pi/6 ?

Answer 1

13 pi over 6 is equivalent to 390 degrees. This is a first quadrant degree angle. The reference angle is the supplementary angle of the angle given. The reference angle is equal to the didifferencef 3 pi and 13 pi over 6. This is equal to 5 pi over 6.

Answer 2

The reference angle is π/6 radians

Explanation:

The reference angle is the angle that the given angle makes with the x-axis. In order to find a reference angle you have to subtract 2π to your angle (notice that your angle, 13/6 π, is greater than 2π).

13/6 π - 2π = 1/6 π or π/6 radians
