Answer 2

=>❣️${ \large { \underline{ \mathcal{ \red{ \huge{answer}}}}}}$❣️

${ \pink{ \frac{ \sin \alpha }{1 + \cos \alpha } + \frac{ \sin \alpha }{ 1 - \cos \alpha } }}$

$\pink{ \frac{ \sin \alpha(1 - \cos \alpha ) + \sin\alpha ( 1 + \cos \alpha ) }{1 - { \cos \alpha }^{2} } }$

$\pink{ = > \frac{ \sin \alpha - \sin \alpha . \cos \alpha + \sin \alpha + \sin \alpha . \cos \alpha }{ { \sin \alpha }^{2} } }$

$= > { \pink{\frac{2 \sin \alpha }{ { \sin }^{2} \alpha } }}$

${ \pink{ \boxed{ \frac{1}{ \sin \theta } = cosec \theta }}}$

$\huge{ \pink{ \boxed {= > {2cosec \: \alpha }}}}$
