Question

If the value of sin θ= -0.798, which of the following could be true about θ?

0 ≤ θ ≤ π/3

π/3 ≤ θ < 2π/3 

2π/3 ≤ θ < 5π/4

5π/4 ≤ θ < 7π/4

7π/4 ≤ θ  < 2π

look at where sin is negative 

3rd quadrant  $$(\pi + \theta)$$ 

and 4th quadrants... 

$$(2\pi - \theta)$$

find the radian value of $$\sin \theta = 0.798$$

just identify which inequalities

i still dont understand, can u break it down any further, plz?

campbell_st · Answer

what is sin (theta) = 0.798

anonymous · Answer

2π

campbell_st · Answer

nope... find 

$$\theta = \sin ^{1}(0.798$$
