Best ResponseYou've already chosen the best response.0Why don't you factor cos theta? :)

Best ResponseYou've already chosen the best response.0If i factor cos theta i would get costheta(2sintheta+1)

Best ResponseYou've already chosen the best response.0then cos theta=0 2sintheta+1=0

Best ResponseYou've already chosen the best response.0it becomes sintheta=1/2

Best ResponseYou've already chosen the best response.0Right so take a look at a unit circle.

Best ResponseYou've already chosen the best response.0No. You should look at the ycoordinate in finding for the sine theta,
