WebFor example, tan 30° = tan 210° but the same is not true for cos 30° and cos 210°. You can refer to the trigonometry formulas given below to verify the periodicity of sine and cosine functions in different quadrants. First Quadrant: sin (π/2 – θ) = cos θ. cos (π/2 – θ) = sin θ. sin (2π + θ) = sin θ.
