Question

What are the sine cosine and tangent of 5pi/3 radians

Answer 1

Explanation:

Take 5pi/3 and subtract 6pi/3 (2 pi). That is the same as -pi/3. That means that the answers are the same as the opposite of pi/3.

Using the Unit circle, the answers are: cosn=1/2 sin= - sqrt(3)/2, tan=sqrt(3)
