We will find the results of trigonometrical ratios of (360° + θ) and (n ∙ 360° + θ). If n is a positive integer then the trigonometrical ratios of (n ∙ 360° + θ) are equal to the trigonometrical ratios of (+ θ). Therefore, sin (n ∙ 360° + θ) = sin θ; cos (n ∙ 360° + θ) = cos θ; Evaluate the given degree value for all trigonometric angles. Let the given degree be θ = 270 °. So, the value of θ for all trigonometric angles is as follows, π 𝛑 π 𝛑 ⇒ sin 270 ° = sin ( 3 × π 2 + 0) [ π 2 = 90 °] sin 270 ° = - cos 0 ° sin 270 ° = - 1 [ c o s 0 ° = 1] Solution.
