Question

What are the sine, cosine, and tangent of 11 pi over 6 radians?

Answer 1

sin(330)= -1/2

cos(330)= sqrt(3)/2

tan(330)= -1/sqrt(3)

Explanation:

Given angle in radians 11 pi/ 6 radians

Convert radians into degree

then find value of sine, cosine and tangent

pi is 180

`(11\pi )/(6) =(11*180)/(6) =330`

sin ( 330)= -0.5

cos(330)=0.866

tan(330)= -0.58

sin(330)= -1/2

cos(330)= sqrt(3)/2

tan(330)= -1/sqrt(3)

Answer 2

This is the concept of trigonometry, the sine, cosine and tangent of 11/6 pi radians will be as follows;
11/6pi=11/6*180=330
thus;
tan 330=-0.5774
sin 330=-0.5
cos 330=-0.8660
