WebAug 18, 2024 · Here, we will look at the cos square theta formula. According to the trigonometric identities, the cos square theta formula is given by. cos 2 θ + sin 2 θ = 1. where θ is an acute angle of a right-angled triangle. Proof: The trigonometric functions for any right angled triangle is defined as: Webθ is an acute angle of a right triangle. sinθ and cosθ are the trigonometric ratios given as follows: sinθ = Altitude/Hypotenuse cosθ = Base/Hypotenuse sin 2 θ is the square of sinθ and cos 2 θ is the square of cosθ i.e, sin 2 θ = (sinθ) 2 cos 2 θ= (cosθ) 2 Thus cos square theta formula is given by, cos 2 θ = 1 - sin 2 θ
