Sketch -2π/3 in standard position and find its reference angle in degrees and radians.
-----
(-2/3)pi = -120 degrees
------
The reference angle is the positive angle between -120 and the
nearest portion or the x-axis.
----
Reference angle = 60 degrees
-----
Reference angle = 60(pi/180) = pi/3 radians
