Websin 2 θ + cos θ = 1, and using the circular identity sin 2 θ + cos 2 θ = 1, it follows that cos 2 θ = cos θ, or ( cos θ − 1) cos θ = 0. Hence cos θ ∈ { 0, 1 }, which implies θ ∈ { ( 2 k + 1) 2 π, 2 k π }, k ∈ Z. You can check this: if θ is an integer multiple of 2 π, then sin θ = 0 and cos θ = 1, so sin 2 θ + cos θ = 1.
