Tan 2x formula in terms of cos x
Tan 2x formula in terms of cos x-I wanted to find $\tan2x$ in terms of $\cos x$ alone I was able to do it in terms of $\sin x$ alone $\tan2x = \sin2x/\cos2x$ Since, $\cos2x = 12\sin^2x$ Therefore, $\tan2x = (\sin2x / 12\sin^2x)$ Is it possible to do it in terms of $\cos x$ alone ?Answer (1 of 22) Cos2x has quite a few formulas 1 \cos2x = 2\cos^2x 1 2 \cos2x = 1 2\sin^2x 3 \cos2x = \cos^2x \sin^2x 4 \cos2x = \dfrac{1 \tan^2x}{1 \tan^2x} Hope these formulas provide you enough help
