Answer» 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 Like my answer if you find it useful!

Answer»

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
