OpenStudy (theraggedydoctor):

Lol wish i could but this is hard... atleast i tried xD

OpenStudy (anonymous):

thanks any way

OpenStudy (theraggedydoctor):

:/ sorry XD

OpenStudy (solomonzelman):

I can say that √3/2 is the value of sin(60)

OpenStudy (anonymous):

any help would be greatly appreciated!!!!!!!

OpenStudy (aravindg):

\[2 \sin \theta \cos \theta=\sin 2 \theta\]

OpenStudy (anonymous):

the part i don't understand is where it says give exact answers

OpenStudy (aravindg):

So indirectly question asks \[\sin 2 \theta=\dfrac{\sqrt{3}}{2}\]

OpenStudy (aravindg):

Theta=?

OpenStudy (anonymous):

Hey I am here

OpenStudy (anonymous):

i am still not sure... can i divide \[(\sqrt{3})/2\] by 2 again?

OpenStudy (aravindg):

assume 2theta=k sin k=root{3}/2 k=?

OpenStudy (anonymous):

so k=root3 over 2 divided by sin?

OpenStudy (aravindg):

Not really. You cant take sin away like that. Just remember that sin 60=root3/2 So 60=k=2theta Then theta=?

OpenStudy (anonymous):

so theta= root 3

OpenStudy (aravindg):

60=2theta then theta=?

OpenStudy (anonymous):

hreeg97 when do you need this.

OpenStudy (anonymous):

so then it should be 30? and tomorrow

OpenStudy (aravindg):

Yes :)

OpenStudy (anonymous):

ok

OpenStudy (aravindg):
