Webb14 apr. 2024 · Using the identity \sin2\theta=2\sin\theta\cos\theta sin2θ = 2sinθcosθ gives X = ( sinθsin2θ)2 = ( sinθ2sinθcosθ)2 = 4cos2 θ. Therefore, the answer is (b). (b). _\square Use the double angle formulas to prove the identity \csc 2\theta - \cot 2\theta = \tan \theta. csc2θ−cot2θ = tanθ. We have WebbThe easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into those last two equations and solve for sin θ/2 and cos θ/2. Then the tangent identity just follow from those two and the quotient identity for tangent. 1 comment ( 18 votes)
Webb8. sin 2 θ =2 s i n θ cos θ (Obtained b y setting x = θ and y = θ in (4)) 9. cos 2 θ =c o s 2 θ − sin 2 θ (Obtained b y setting x = θ and y = θ in (6)) WebbUsing one of the trigonometric identities, we have sin 2 x + cos 2 x = 1. Subtracting cos 2 x from both sides, we get sin 2 x = 1 - cos 2 x. Thus, one of the sin squared x formulas is, sin2 x = 1− cos2x sin 2 x = 1 − cos 2 x. Using one of the double angle formulas of cosine function, we have cos 2x = 1 - 2 sin 2 x.
