Question
**Question:**

Which of the following is not in the domain of \( \cot(x) \)? Select all correct answers.

**Options:**

- [ ] \( -\pi \)
- [ ] \( \frac{\pi}{6} \)
- [ ] \( \frac{\pi}{2} \)
- [ ] \( \frac{3\pi}{2} \)
- [ ] \( 0 \)

**Explanation:**

The cotangent function, \( \cot(x) \), is undefined where the sine of \( x \) is zero. These points occur at integer multiples of \( \pi \) (e.g., \( 0, \pi, -\pi \), etc.). Therefore, values in the options that are multiples of \( \pi \) are not in the domain of \( \cot(x) \) because they would result in division by zero.
