Prove the following identity. (sin x−cos x)2=1−sin 2x Trigonometric Identities: Due to the close relationship between the sine and cosine functions and the points on the unit circle, there are many identities which may be proven using the equation sin2x+cos2x=1 and o...
2sin(45°-x)cos(45°-x)=sin(2*(45°-x)) 上式是因为倍角公式sin2x=2sinxcosx,将45°-x看成一个角. 所以sin(2*(45°-x))=sin(90°-2x)=cos2x (由正弦与余弦的关系式可得) 分析总结。 上式是因为倍角公式sin2x2sinxcosx将45x看成一个角结果一 题目 prove the identity:2sin(45'-x)cos...
