Question
**Find the derivative.**

Given:  
\[y = \frac{\sin x}{8x} + \frac{8x}{\sin x}\]

**Options:**

1. \(\frac{dv}{dx} = \frac{\cos x}{8} + \frac{8}{\cos x}\)

2. \(\frac{dv}{dx} = \frac{x \cos x + \sin x}{8x^2} + \frac{8 \sin x + 8x \cos x}{\sin^2 x}\)

3. \(\frac{dv}{dx} = \frac{\sin x - x \cos x}{64x^2} + \frac{8x \cos x - 8 \sin x}{\sin^2 x}\)

4. \(\frac{dv}{dx} = \frac{x \cos x - \sin x}{8x^2} + \frac{8 \sin x - 8x \cos x}{\sin^2 x}\)
