Question

Please help ASAP!!! Find the exact values of cos and sin for the angle measure.
5pi/6 radians

Answer 1

(5pi/6)(180/pi) = 150 degrees or 30 degree angle in QII. 

sin 150 = 1/2 
cos 150 = -(sqrt 3)/2 
tan 150 = -1/sqrt 3 = -(sqrt 3)/3 
cot 150 = -sqrt 3 
sec 150 = (-2 sqrt 3)3 
csc 150 = 2
