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

Answer 1

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

Answer 2

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

Answer 3

what is sin (theta) = 0.798

Answer 4

2π

Answer 5

nope... find

\[\theta = \sin ^{1}(0.798\]

Answer 6

do you know about the unit circle and where trig ratios are positive and negative..?
