Verify the identity: \frac{\sin 2x}{1 - \cos 2x} = \cot x. Verify the Identity: csc (x) + cot (x) = {sin (x)} / {1 - cos (x)} Verify the identity: cot x + tan x = sec x csc x. Verify the identity. {2 sin x cot x + sin x - 4 cot x - 2} / {2...
1-sin(x) 1−sin(x)1-sin(x) Rewrite1−sin(x)1-sin(x)as1−1csc(x)1-1csc(x). 1−1csc(x)1-1csc(x) Because the two sides have been shown to beequivalent, theequationis anidentity. cos2(x)1+sin(x)=1−1csc(x)cos2(x)1+sin(x)=1-1csc(x)is anidentity ...
Verify the identity: {eq}cos x + sin x tan x = sec x. {/eq} Proving: We have to prove that both sides of the given equation are equal. This is done by taking the more complicated side (the L.H.S. here) and trying to simplify it till we make it the same as the other s...
根据这些定义,可得到下列恒等式(identity):tanθ=sinθ/cosθ,cotθ=cosθ/sinθ secθ=1/cosθ,cscθ=1/sinθ 分别用cos 2θ与sin 2θ来除cos 2θ+sin 2θ=1,可得:sec 2θ–tan 2θ=1 及 csc 2θ–cot 2θ=1 对于负角度,六个三角函数分别为:sin(–θ)=–sinθ csc(–θ)=–cscθ cos...
