Question

Prove that Cos A/1+Sin A + 1+SinA / Cos A = 2 Sec A? Please answer it fast as you can​

Answer 1

cos/(1 + sin) + (1 + sin)/cos = 2 sec      common denominator is cos(1 + sin)

[ cos · cos + (1 + sin)(1 + sin) ] / [cos(1 + sin)] = 2 sec 

[ cos2 + sin2 + 2 sin + 1 ] / [cos(1 + sin)] = 2 sec

[ 1 + 2 sin + 1] /  [cos(1 + sin)] = 2 sec

[ 2 sin + 2] / [cos(1 + sin)] = 2 sec

[ 2(sin + 1] / [cos(1 + sin)] = 2 sec

2 1/cos = 2 sec

2 sec = 2sec
