Answer 2

Answer:

LHS =

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