## ihatealgebrasomuch Group Title is the sin120 degrees -1/2? one year ago one year ago

$\sin 120=\sin (180-60)=\sin 60=\sqrt {3}$

/2

3. dpaInc Group Title

just remember that on the unit circle, sin is your y-coordinate cos is your x-coordinate.

4. ZeHanz Group Title

Still on the top-half of the unit circle, so sin is positive there...

is this a complete question

what is it looking for

7. dpaInc Group Title

it's basically a yes/no question...

8. ihatealgebrasomuch Group Title

it just said find each trigonometric ratio and gave me sin120.

9. ihatealgebrasomuch Group Title

oh i see, so since sin is the y axis, it would be sqrrt3/2

10. dpaInc Group Title

correct... sin is the y-coordinate, not the y axis...
