hello Frnd

here is your Answer.


Given that

tan \: a \:   \times tan \frac{a}{2}  + 1 = sec \: a
  \frac{ \sin(a) }{ \cos(a) }  \times  \frac{1 -  \cos(a) }{ \sin(a) }  + 1 \\  \frac{ \sin(a)  -  \cos(a)  \sin(a) }{ \sin(a) \cos(a)  }  + 1  \\ \  \frac{ \sin(a)  -  \cos(a)  \sin(a) }{ \sin(a) \cos(a)  } +  \ \frac {sin(a)  cos(a)}{ \sin(a) \cos(a)  } \\  \frac{ \cos(a)  \sin(a)  +  \sin(a)  -  \sin(a) \cos(a)  }{ \cos(a) \sin(a)  }  \\  \\ after \: elimination \: of \: 1st \: and \: 3rd \:  \:  \:  \:  \:  \:  \:  \: we \: get \:  \\  \\   \frac{ \sin(a) }{ \cos(a)  \sin(a) }  \\  \\  \frac{1}{ \cos(a) }  \\   = \sec(a)


hence proved




hope it helps
