WebPrecalculus. Solve for ? cos (3theta)=1. cos (3θ) = 1 cos ( 3 θ) = 1. Take the inverse cosine of both sides of the equation to extract θ θ from inside the cosine. 3θ = arccos(1) 3 θ = arccos ( 1) Simplify the right side. Tap for more steps... 3θ = 0 3 θ = 0. Divide each term in 3θ = 0 3 θ = 0 by 3 3 and simplify. WebFrom the unit circle definition, the coordinates of the point M are (cosθ, sinθ). And so, ¯ OC is cosθ and ¯ OS is sinθ. Therefore, OM = √ ¯ OC2 + ¯ OS2 = √cos2θ + sin2θ. Since M lies in the unit circle, OM is the radius of that circle, and by definition, this radius is equal to 1.
