{eq}\sin 2x(\tan x + \cot x) = 2 {/eq} Identities: In trigonometry, an equation consisting of any of the six trigonometric ratios (sine, cosine, tangent, secant, cosecant, and tangent) becomes an identity, when such equation holds true for any random value of the unknown. Fo...
{eq}\sin \left( {2x} \right) = {{2\tan x} \over {1 + {{\tan }^2}x}} {/eq} Verifying Trigonometric Identities: In trigonometry, trigonometric identities are the combination of trigonometric functions and mathematical operators. The trigonometric identities consist of two sides, and...
Recalls a correc trig identity, which could lead to a correc answer Demonstrates a strategy for proving the identity, eg by converting all the terms on the LHS to cos and sin. Concludes a rigorous mathematical argumen to prove given identity AG (LHS=){{sin2x}\over{1+{tan}^{...

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...
