Explanation:
1+sinx1−sinx=(secx+tanx)2
Right Side =(secx+tanx)2
=(secx+tanx)(secx+tanx)
=sec2x+2secxtanx+tan2x
=1cos2x+2⋅1cosx⋅sinxcosx+sin2xcos2x
=1+2sinx+sin2xcos2x
=(1+sinx)(1+sinx)1−sin2x
=(1+sinx)(1+sinx)(1+sinx)(1−sinx)
=1+sinx1−sinx
= Left Side
1+sinx1−sinx=(secx+tanx)2
Right Side =(secx+tanx)2
=(secx+tanx)(secx+tanx)
=sec2x+2secxtanx+tan2x
=1cos2x+2⋅1cosx⋅sinxcosx+sin2xcos2x
=1+2sinx+sin2xcos2x
=(1+sinx)(1+sinx)1−sin2x
=(1+sinx)(1+sinx)(1+sinx)(1−sinx)
=1+sinx1−sinx
= Left Side
