Question

cot theta 7/18. Where theta lies in quadrant 3. What is csc?

Answer 1

use your trig identities ,

1+cot^2 θ = csc ^2 θ

1+ cot^2 θ = 4

cot^2 θ = 3

cot θ = √3

since quadrant 2 it is negative

-√3


2) 1 + 49/324 = csc^2 θ

csc θ = √373 / 18

this is also negative.

Answer 2

i hope i helped
