The value of the following is: $$\frac{\sin\theta\ \cos ec\theta\ \tan\theta\ \cot\theta}{\sin^{2}\theta+\cos^{2}\theta}$$
Expression : $$\frac{\sin\theta\ \cos ec\theta\ \tan\theta\ \cot\theta}{\sin^{2}\theta+\cos^{2}\theta}$$
= $$\frac{(sin\theta\times\frac{1}{sin\theta})\times(tan\theta\times\frac{1}{tan\theta})}{1}$$
= $$1$$
