Hey guys, it's my first post here so please don't chew my head off if I do something forbidden, hahah. 1. The problem statement, all variables and given/known data Prove the Law of Sines using Vector Methods. 2. Relevant equations sin(A)/a = sin(B)/b = sin(C)/c 3. The attempt at a solution Since axb=sin(C), I decided to try getting the cross product and then trying to match it to the equation. I gave each of the points coordinates and I decided to come here for help when the problem became gigantic and hardly manageable. I've spent a couple of hours on this and I'm not getting anywhere. If you've got any suggestions for a simpler solution or even just a nudge in the right direction, I'd be very grateful.
