Question

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

need whole solution​

Answer 1

Step-by-step explanation:

L.H.S :-

(1-sinA)/cosA

Rationalize the numerator:-

(1-sinA)(1+sinA) / cosA(1+sinA)

1²-sin²A / cosA(1+sinA)

1 - sin²A / cosA(1+sinA)

We know that 1-sin²A = cos²A

cos²A / cosA(1+sinA)

Cancelling cosA

cosA/(1+sinA) = R.H.S
