Question

Simplified expression of \[ 1 - \frac{\sin^2 y}{1 + \cos y} + \frac{1 + \cos y}{\sin y} - \frac{\sin y}{1 - \cos y} \]

• A. \( \sin y \)
• B. \( \cos y \)
• C. 1
• D. 0

Hint:

When simplifying trigonometric expressions, use standard identities like \( \sin^2 y + \cos^2 y = 1 \) to eliminate terms and simplify the expression.
