Answer 1

Step-by-step explanation:

$\frac{ \sin(a) }{1 - \frac{ \cos(a) }{ \sin(a) } } + \frac{ \cos(a) }{1 - \frac{ \sin(a) }{ \cos(a) } } = \sin(a) + \cos(a)$

$\frac{ \sin(a) }{ \frac{ \sin(a ) - \cos(a) }{ \sin(a) } } + \frac{ \cos(a) }{ \frac{ \cos(a) - \sin(a) }{ \cos(a) } } = \sin(a) + \cos(a)$

$\frac{ { \sin(a) }^{2} }{ \sin(a ) - \cos(a) } + \frac{ { \cos(a) }^{2} }{ \cos(a) - \sin(a) } = \sin(a) + \cos(a)$

$\frac{ { \sin(a) }^{2} }{ \sin(a) - \cos(a) } - \frac{ { \cos(a) }^{2} }{ \cos(a) - \sin(a) } = \sin(a ) + \cos(a)$

$\frac{( \cos(a) + \sin(a))( \cos(a) - \sin(a) ) }{ \cos(a) - \sin(a) } = \sin(a) + \cos(a)$

now cos a-sin a would cancel and the remaining would be the answer
