What are the sine, cosine, and tangent of 2π over 3 radians?

Solution:

Angles are formed when two lines intersect at a point. The measure of the 'opening' between these two rays is called an 'angle'.

It is represented by the symbol ∠.

Angles are usually measured in degrees and radians, which is a measure of circularity or rotation.

Given angle 2π over 3 radians

sin(2π over 3 radians) = sin(2π/3) = 0.866

cosine(2π over 3 radians) = cos(2π/3) = -0.5

tan(2π over 3 radians) = tan( 2π/3) = -1.73

Therefore, the sine, cosine, and tangent of 2π over 3 radians are 0.866, -0.5, -1.73.

What are the sine, cosine, and tangent of 2π over 3 radians?

Summary:

The sine, cosine, and tangent of 2π over 3 radians are 0.866, -0.5, -1.73 respectively.
