17 kwi 2018 · The exact value for sin 2π 3 = √3 2. For the unit circle sin 2π 3 is in the 2nd quadrant making sine positive. For the unit circle values on the 60o angles all have a value of (1 2, √3 2) where x = cosine and y = sine. 2π 3 = 120o. Making the sin 2π 3 = √3 2. Answer link.
Trigonometry is a branch of mathematics concerned with relationships between angles and side lengths of triangles. In particular, the trigonometric functions relate the angles of a right triangle with ratios of its side lengths.
