Question

Which of the following trigonometric values are negative? 1. sin(-292°) II. tan (2pi/3°) III. cos (153°) IV. cot (222°)a. 2, 3, and 4b. 2 and 3c. 3 onlyd. 1 and 3

Answer 1

`\begin{gathered} \sin (-292)=0.927 \\ \tan ((2\pi)/(3))=-\sqrt[]{3} \\ \cos (153)=-0.891 \\ \cot (222)=1.11 \end{gathered}`

Therefore, the answer is:

b. 2 and 3
