Use Complementary Angle Identity: Express tan(2π−θ) using the complementary angle identity for tangent, which states that tan(2π−θ)=cot(θ).
Reciprocal of Tangent: Recall that cot(θ) is the reciprocal of tan(θ), so cot(θ)=tan(θ)1 or cot(θ)=sin(θ)cos(θ).
Substitute and Simplify: Substitute cot(θ) with sin(θ)cos(θ) in the given expression to get (sin(θ)cos(θ))⋅sin(θ).
Substitute and Simplify: Substitute cot(θ) with sin(θ)cos(θ) in the given expression to get (sin(θ)cos(θ))⋅sin(θ). Simplify the expression by canceling out the sin(θ) in the numerator and the denominator to get cos(θ).
