How do i to find sinx/2 if sinx = 9/14 and x in Quadrant 2 using the half angle formula I can only use half angle forumulas, nothing else, any ideas? im stuck aaaah, okay thanks Min, that really cleared things up, thanks a lot

How to find sinx/2 if sinx = 9/14 and x in Quadrant 2 using the half angle formula ... i have to solve it through the half angle formula, an example of an half angle formula: + or - sqrt (1-cosx over 2)
