Question

Find the exact values of cos 150º and sin 150º.

Answer 1

Cos150= .6992508065
Sin150= -.7148764296

Answer 2

here i the answers

Cos = –1/2, sin = (3/2
Cos = 1/2, sin = (3/2
Cos = –(3/2, sin = 1/2
Cos =(3/2 , sin = –1/2

Answer 3

\[\cos 150= \cos (180-30)=-\cos30=-\frac{ \sqrt{3} }{ 2 }\]

Answer 4

did u get it

Answer 5

i think u can try for sin 150 in this way

Answer 6

\[would \it be 2. \cos =1/2, \sin= \sqrt{3}/2\]
