WebThe law of cosines is used to find the missing side of a triangle when its two sides and the included angle is given. There are three laws of cosines and we choose one of them to solve our problems depending on the available data. a 2 = b 2 + c 2 - 2bc·cosA b 2 = c 2 + a 2 - 2ca·cosB c 2 = a 2 + b 2 - 2ab·cosC Web9 mrt. 2024 · Since the law of sines says a / sin A = b / sin B = c / sin C = 2R it's pretty easy to derive! I know a lot of books leave off the "= 2R" part, and some even go so far as to put the sines on top instead of on the bottom. I think the best way to prove the law of sines is to prove that a / sin A = 2R and then by symmetry the rest follows.
