Which of the following correctly expresses tan⁡θ\tan\theta in terms of sin⁡θ\sin\theta and cos⁡θ\cos\theta? (a) tan⁡θ=cos⁡θsin⁡θ\tan\theta=\dfrac{\cos\theta}{\sin\theta} (b) tan⁡θ=sin⁡θcos⁡θ\tan\theta=\dfrac{\sin\theta}{\cos\theta} (c) tan⁡θ=sin⁡θcos⁡θ\tan\theta=\sin\theta\cos\theta (d) tan⁡θ=1−cos⁡2θcos⁡θ\tan\theta=\dfrac{1-\cos^{2}\theta}{\cos\theta}
