WebApr 27, 2015 · Use sin(2θ) = 2sinθcosθ. Then factor and solve. sin(2θ) +sinθ = 0. 2sinθcosθ +sinθ = 0. sinθ(2cosθ +1) = 0. sinθ = 0sssss or sssss 2cosθ + 1 = 0 so. sinθ = 0sssss or sssss cosθ = − 1 2. θ = 0, 2π 3,π or 4π 3. Answer link. WebPrecalculus. Solve for ? 6sin (x)+3=0. 6sin(x) + 3 = 0 6 sin ( x) + 3 = 0. Subtract 3 3 from both sides of the equation. 6sin(x) = −3 6 sin ( x) = - 3. Divide each term in 6sin(x) = −3 6 sin ( x) = - 3 by 6 6 and simplify. Tap for more steps... sin(x) = − 1 2 sin ( x) = - 1 2. Take the inverse sine of both sides of the equation to extract ...
