Answer 2

Heya mate,Here is ur answer

$\huge \red{ \mathfrak{answer}}$

Sec ^4 A - Sec ^2 A = Tan ^4 A + Tan^2A

Taking LHS

Sec^4 A -Sec^2 A

Taking Sec^2 A common

Sec^2 A(sec^2 A-1)

We know that

⏩1+ tan^2 A= sec^2 A

⏩tan^2 A = sec^2 A-1

So,

Sec^2 A(sec^2 A-1)

= sec^2 A× tan^2 A

= (1+ tan^2 A) tan^2 A

Now multiplying

= Tan^2 A + Tan^4A

= Tan^4 A + Tan^2 A

Hence proved
