Vedclass · Answer

(D) We are given the expression: $	an 	heta \sin \left( \frac{\pi }{2} + 	heta ight) \cos \left( \frac{\pi }{2} - 	heta ight)$.Using the trigonometric identities $\sin \left( \frac{\pi }{2} + 	heta ight) = \cos 	heta$ and $\cos \left( \frac{\pi }{2} - 	heta ight) = \sin 	heta$,the expression becomes:$= 	an 	heta \cdot \cos 	heta \cdot \sin 	heta$$= \left( \frac{\sin 	heta}{\cos 	heta} ight) \cdot \cos 	heta \cdot \sin 	heta$$= \sin 	heta \cdot \sin 	heta$$= \sin^2 	heta$.

$\tan \theta \sin \left( \frac{\pi }{2} + \theta \right) \cos \left( \frac{\pi }{2} - \theta \right) = $
