Answer 1

$\frac{ \sin( \alpha ) }{1 + \cos( \alpha ) } + \frac{1 + \cos( \alpha ) }{ \sin( \alpha ) } \\ \frac{ \sin( \alpha )(1 - \cos( \alpha ) ) }{ { \sin( \alpha ) }^{2} } + \csc( \alpha ) + \tan( \alpha ) \\ \sec( \alpha ) - \tan( \alpha ) + \csc( \alpha ) + \tan( \alpha ) \\ 2 \csc( \alpha )$
