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) Webb本页面最后修订于2024年2月23日 (星期四) 16:17。 本站的全部文字在知识共享 署名-相同方式共享 3.0协议 之条款下提供，附加条款亦可能应用。（请参阅使用条款） Wikipedia®和维基百科标志是维基媒体基金会的注册商标；维基™是维基媒体基金会的商标。 WebbIt is used to expand the two times the sin squared of angle as the one minus cosine of double angle. 2 sin 2 θ = 1 − cos ( 2 θ) Other forms The angle in the one minus cos double angle trigonometric identity can be denoted by any symbol.
