Question

prove the following for me plzz​

Answer 1

sec⁴A(1+sin⁴A)=sec⁴A+tan⁴A.

THUS PROVED

Answer 2

on opening bracket:LHS

=sec^4A + sec^4A × sin^4A

=sec^4A + 1/cos^4A × sin^4A. {secA=1/cosA}

=sec^4A + sin^4A/cos^4A

=sec^4A + tan^4A. {sinA/cosA=tanA}

thus proved,

LHS=RHS

HOPE IT WAS HELPFUL
