Question

I want solution of this question​

Answer 1

x = Sec² A - tan A/ Sec² A +tan A

= 1 + tan² A - tan A / 1+ tan² A + tan A

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

= 1 + sin A / cos A (sin A- cos A/ cos A)/ 1+ sin A/ cos A (sin A+ cos A/ cos A)

= cos A + sin A (sin A - cos A) / Cos² A / cos A + sin A ( sin A + cos A) / Cos² A

If may be option A
