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.
Solution steps. sin(3(2π)) = sin(32π) Use the following trivial identity: sin(32π) = 23. = 23. Enter your problem. Popular Examples.
The value of sin 2pi/3 can be calculated by constructing an angle of 2π/3 radians with the x-axis, and then finding the coordinates of the corresponding point (-0.5, 0.866) on the unit circle. The value of sin 2pi/3 is equal to the y-coordinate (0.866). ∴ sin 2pi/3 = 0.866.
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.
