Salzig Posted December 5, 2007 Share Posted December 5, 2007 I don't want to go through the problem, but some identities that may come in handy are: 1) sin^2(x) + cox^2(x) = 1 -> Rearrange for sin^2(x) and sub into your equation. You then have a quadratic equation in cos(x) - solve it by factoring or using the quadratic formula. (ie let y = cos(x), then you have ay^2 + by + c = 0) 2) sin(2x) = 2sin(x)cos(x) is all you need. Sub that in, and a bit of algebra & factoring will give you the answer. EDIT: you beat me to it. Good job! Link to comment Share on other sites More sharing options...
mikro112 Posted December 5, 2007 Share Posted December 5, 2007 Sorry, but I've got a (maybe stupid) question: What does this ---> ^ <--- sign mean? I've never seen it before... And I'm actually good at maths (and even better in German ) Link to comment Share on other sites More sharing options...
