Nov 17, 2023 ... I know that if we do Sin( A+B )we get (sinA*cosB)+(SinB * CosA) Why not just do SIN (A+B) where A+B=C so it is just take SIN(C)? As for the Feb 16, 2018 ... 4 Answers 4 · b+a=π2 since |eia+ei(π−b)|2=2⟹Law of Cosines⏞2=2+2cos((π−b)−a) · b−a=π3 since a+(π−b)2=π3. cos C + v' sin C + w cos B — wr sin B)a.
