1. ## roots

Determine the roots for the equation -3 sin θ -1 = 1 between 0° and 360°

a/41.8° and 138.2°
b/138.2° and 221.8°
c/221.8° and 318.2°
d/138.2° and 318.2°
e/221.8° and 318.2°

2. ## Re :

$-3sin\theta=2$

$
sin\theta=-2/3
$

The angle is negative , hence it can be either in the third or fourth quadrant .
