( 1 + tan^2 a) / ( 1 + cot^2 a )

L. H. S. = Sec^2 a / cosec^2a

L. H. S. = 1 / cos^2 a / 1 / sin^2a

L. H. S. = Sin^2 a / Cos ^2 a

L. H. S. = tan^2 a

L. H. S. = R. H. S.

Again,

L. H. S. = ( 1 - tan a ) ^2 / ( 1 - cot a ) ^2

= ( 1 + tan^2a - 2 tan a ) / ( 1 + cot^2 a - 2 cot a )

= ( sec^2 a - 2 tan a ) / ( cosec^2 a - 2 cot a )

= ( 1 / cos^2 a - 2 sin a / Cos a ) / ( 1 / sin^2 a - 2 cos a /sin a )

= ( 1 - 2 sin a cos a / cos^2 a) ( 1 - 2 cos a sin a / sin ^2 a )

= sin^2 a / Cos ^2 a

= tan^2 a

L. H. S. = R. H. S.
