Question

Please Answer this :

Answer 1

LHS=
$\frac{ \cos( a) }{1 - \sin(a) } + \frac{ \sin(a) }{1 - \cos(a) } + 1$
$\frac{ \cos(a)(1 - \cos(a)) + \sin(a) (1 - \sin(a)) + (1 - \sin(a))(1 - \cos(a) }{(1 - \sin(a))(1 - \cos(a) ) }$
$\frac{ \cos(a) - {{ \cos(a) }^{2} + \sin(a) - { \sin(a) }^{2} + 1 - \sin(a - \cos(a) + \sin(a) \cos(a) ) } }{(1 - \sin(a))(1 - \cos(a) }$
$\frac{ \sin(a) \cos(a) }{(1 - \sin(a) )(1 - \cos(a)) }$
=RHS



hence this is the step to step solution
