Question

What are the sine, cosine, and tangent of (2 pi)/3 radians?

Answer 1

Sine(2pi)/3= Sqrt(3)/2

Answer 2

sin(2.09)=0.036

cos(2.09)=1

tan(2.09)=0.036

Explanation:

The sine, cosine and tangent functions can be determine of 2π/3. We calculate the radians first:

`2\cdot{\pi}/3=2.09`

Therefore:

sin(2.09)=0.036

cos(2.09)=0.999≈1

tan(2.09)=0.036
