\tan 2x = \sec 2x + \sin 2x - \cos 2x Use an identity to write the expression as a single trigonometric function. (sin 14)/(1 + cos 14) Use trigonometric identities to write the expression in terms of a single trigonometric identity or a constant. (sin x)/(1 - cos x) + (1...
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...
Use the identities tan(x) = sin(x)/cos(x) and csc(x) = 1/sin(x) to get: 1/(tan(x) × csc(x)) = 1/[(sin(x)/cos(x) × 1/sin(x)] Now just work with the denominator (bottom) of the rational expression (fraction): sin(x)/cos(x) × 1/sin(x) = 1/cos(x) Now...
