WebThe trigonometric ratios of 60 ^\circ ∘. The process of deriving the trigonometric ratios for the special angles 30^\circ 30∘, 45^\circ 45∘, and 60^\circ 60∘ is the same. While we have not yet explicitly shown how to find the trigonometric ratios of 60^\circ 60∘, we have all of the information we need! Webcos ( 60 ∘) cos θ + sin ( 60 ∘) sin θ = 1 2 sin θ. 2 cos ( 60 ∘) cos θ + 2 sin ( 60 ∘) sin θ = sin θ. You can then substitute the values of sin ( 60 ∘) and cos ( 60 ∘) into the equation, and …
WebIn trigonometrical ratios of angles (180° - θ) we will find the relation between all six trigonometrical ratios. We know that, sin (90° + θ) = cos θ. cos (90° + θ) = - sin θ. tan (90° + θ) = - cot θ. csc (90° + θ) = sec θ. sec ( 90° + θ) = - csc θ. cot ( 90° + θ) = - tan θ. and.
