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.](https://content.bartleby.com/qna-images/question/24f7b9fc-b934-4e37-ae35-bdc4b8c3050d/86a59313-1ae3-4f80-8fc2-dcf6611718ae/jdr1v4_thumbnail.png)
