Options

A. `sec^(2)x`
B. `-sec^(2)((pi)/(4)-x)`
C. `sec^(2)((pi)/(4)+x)`
D. `sec^(2)((pi)/(4)-x)`

Explanation

To solve the problem of finding the derivative of \( y = \sqrt{\frac{1 - \sin 2x}{1 + \sin 2x}} \) with respect to \( x \), we will follow these steps:

### Step 1: Rewrite the expression
Let
\[ y = \sqrt{\frac{1 - \sin 2x}{1 + \sin 2x}} \]
