Answer» Prove : ____________________ __________ sec^4 X - sec^2 x = tan^4 x + tan^2 x ______________________________ L .H. S sec^4 x - sec^2 x =sec^2 x ( sec^2 x - 1 ) [note : sec^2 x - 1 = tan^2 x or sec^2 x = tan^2 x + 1 ] = sec^2 x ( tan^2 x ) = ( tan^2 x + 1 ) ( tan^2 x ) = tan ^4 x + tan^2 x = R .H.S L. H. S = R. H. S hence, PROVED _______________________________ || :hope HELPS : || _______________________________ |
