Plz give answer in detail
Find the trignometric function of an angle 2π/3.

Answer 1

Answer:

sin at 2π3 = √32

Explanation:

The exact value for sin2π3 = √32

For the unit circle sin2π3 is in the 2nd quadrant making sine positive.

For the unit circle values on the 60o angles all have a value of (12,√32) where x= cosine and y=sine

2π3 = 120o

Making the sin2π3 = √32
