SOLUTION: Convert 2pi/3 radians to degree

Question 1198654: Convert 2pi/3 radians to degree
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
angle in degrees is equal to angle in radians * 180 / pi
angle in radians is equal to angle in degrees * pi / 180.

examples:

360 degrees * pi / 180 = 2 * pi radians.
2 * pi radians * 180 / pi = 360 degrees.

your angle is 2 * pi / 3 radians.
multiply that by 180 / pi to get 120 degrees.

you can use your calculator to confirm these angles are equivalent.
set your calculator to degrees and get tan(120) = -1.732050808.
set your calculator to radians and get tan(2 * pi/3) = -1.732050808.
