$	an 	heta $

Vedclass · Answer

(c) $\frac{{\sin 	heta + \sin 2	heta }}{{1 + \cos 	heta + \cos 2	heta }}$

$ = \frac{{\sin 	heta + 2\sin 	heta \cos 	heta }}{{2{{\cos }^2}	heta + \cos 	heta }} $

$= \frac{{\sin 	heta (1 + 2\cos 	heta )}}{{\cos 	heta (1 + 2\cos 	heta )}} $

$= 	an 	heta $.

Trick : Put $	heta = 30^\circ $, 

since for $	heta = 30^\circ $ no option will give the common value.

$\frac{{\sin \theta + \sin 2\theta }}{{1 + \cos \theta + \cos 2\theta }} = $
