Answer:

(Sec A + Cos A) (Sec A - Cos A)

We know that,

(a - b) (a + b) = a² - b²

Here,

a = Sec A

b = Cos A

Substituting,

Sec² A - Cos ² A

We know that,

1 + Tan² A = Sec² A

1 - Sin² A = Cos² A

Substituting,

1 + Tan² A - (1 - Sin² A)

1 + Tan² A - 1 + Sin² A

Tan² A + Sin² A

Therefore,

\boxed{\purple{\textsf{(Sec A + Cos A) (Sec A - Cos A) = Tan² A + Sin² A}}}

(Sec A + Cos A) (Sec A - Cos A) = Tan² A + Sin² A
