WebStep 1. Find the value of c o s θ + s i n θ: Given, cos θ - sin θ = 2 sin θ square both sides, we get cos 2 θ + sin 2 θ – 2 sin θ cos θ = 2 sin 2 θ ⇒ 1 – 2 sin θ cos θ = 2 sin 2 θ ⇒ 2 sin θ cos θ = 1 – 2 sin 2 θ …. (i) Now, consider cos θ + sin θ Step 2. By Squaring this expression, we get 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.
