Answer:

Step-by-step explanation:

LHS=(secA+tanA−1)(secA−tanA+1)

      =(

cosA

1

+

cosA

sinA

−1)(

cosA

1

cosA

sinA

+1)

      =(

cosA

1+sinA−cosA

)(

cosA

1−sinA+cosA

)

      =

cos

2

A

1−sinA+cosA+sinA−sin

2

A+sinAcosA−cosA+sinAcosA−cos

2

A

      =

cos

2

A

2sinAcosA

      =2tanA

     =RHS

Hence proved
