Answer 1

Step-by-step explanation:

Sorry for the poor handwriting ...... Hope you are satisfied

Answer 2

Answer:

as we know sec A = 1/ Cos A

By putting the value in L.H.S we get 1+ cos A

again R.H.S

sin^2 A / 1- Cos A

= 1- Cos ^2 A / 1 - Cos A

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

= 1+ Cos A
