Hey! I just wanted to post what I was getting confused on, concerning Sin and the whole Soh Cah Toa thing. The Law of Siness is sinA = sinB= sinC ---- ---- ---- a b c and the other one was actually the Law of Cosines, which is: c squared= a squared + b squared - 2ab cosC cos C= a squared+ b squared- c squared divided by 2ab. What I still don't quite know is when these laws need to be used... Thanks!
