Answer 1

Answer:

Q is wrong buddy try next time

Answer 2

Step-by-step explanation:

Let us take R.H.S=

cosA =

1- sin A

cos A (1+ sin A)

1- sin A ( 1+sin A). [ multiplying 1+sin A in both D and N]

= cos A ( 1+sinA)

cos^2 A

= cos A (1+sin A ). as cos^2 A= (cos a)^2

(cos A)^2

= 1+ sin A

cos A

= L.H.S

hence proved
