The value of the expression

1 - \frac{{{{\sin }^2}\,\,y}}{{1 + \cos \,\,y}} + \frac{{1 + \cos \,\,y}}{{\sin \,\,y}} - \frac{{\sin \,\,y}}{{1 - \cos \,\,y}}

is equal to

View answer and explanation

Correct option: D

\cos \,\,y

Option D (cos y) is correct because the expression simplifies to cos y after applying trigonometric identities and algebraic manipulation.
