Question

(secθ+tanθ-1)(secθ-tanθ+1)= ?​

Answer 1

Answer:

L.H.S=

1+secθ+tanθ

1+secθ−tanθ

=

secθ+tanθ+1

secθ−tanθ+1

=

secθ+tanθ+1

secθ−tanθ+(sec

2

θ+tan

2

θ)

[∵sec

2

θ−tan

2

θ=1]

=

secθ+tanθ+1

secθ−tanθ+(secθ−tanθ)(secθ+tanθ)

=

(1+secθ+tanθ)

(secθ−tanθ)(1+secθ+tanθ)

=

cosθ

1

−

cosθ

sinθ

=

cosθ

1−sinθ

=R.H.S

Hence proved.
