RHS

  {( \sec( \alpha ) -  \tan( \alpha )  })^{2}  \\  {( \frac{1 -  \sin( \alpha ) }{ \cos( \alpha ) } })^{2} \\ we \: know \: that \\  1 - { \sin( \alpha ) }^{2} =  { \cos( \alpha ) }^{2}   \\ so  \\  \frac{(1 -  \sin( \alpha )(1 -  \sin( \alpha ) ) }{(1 -  \sin( \alpha )(1 +  \sin( \alpha ) ) }  \\  \frac{1 -  \sin( \alpha ) }{1 +  \sin( \alpha ) }

Hence RHS = LHS
