Question

please prove this sum

Answer 1

Hii..

===============================================

= secA+tanA-1 /tanA-secA+1

= tan A + sec A - (sec²A - tan² A ) / tan A - sec A + 1

= tan A + sec A + ( 1 + tan A - sec A) / tan A - sec A + 1

= tan A + sec A

= sin A / Cos A + 1 / cos A

= 1 + sin A / Cos A

= Hence LHS = RHS

===============================================

Hope it will help u...............
