WebThe angle sum identity says sin(a +b) = sinacosb +sinbcosa. Plug in the values you are given. The single digit numbers make a calculator optional. Given any a,b, find A,B such that asin(x)+ bcos(x) = Asin(x +B) Let θ be such that cosθ = a/ a2 + b2 and sinθ = b/ a2 +b2. Websin ( B + 2 C) + sin ( C + 2 A) + sin ( A + 2 B) = sin ( π − A + C) + sin ( π − B + A) + sin ( π − C + B) = − sin ( C − A) − sin ( A − B) − sin ( B − C) Now our problem only depends on …
