Question

$\sin \theta \cos \theta \tan \theta +\cos \theta \cot \theta \sin \theta =$

• A. 1
• B. 2
• C. $\tan \theta$
• D. $\cot \theta$

Answer 1

The correct option is A 1

Write $\tan \theta =\frac{sin\theta }{\cos \theta }$ and $\cot \theta =\frac{\cos \theta }{\sin \theta }$

$si{n}^2\theta +co{s}^2\theta =1$
