Create a table of values of sin(1/x) for the following values of x: 2/pi, 2/3pi,2/5pi, 2/7pi, 2/9pi, 2/11pi
![### Analyzing the Behavior of \( \sin \left( \frac{1}{x} \right) \) Near \( x = 0 \)
Consider the function \( \sin \left( \frac{1}{x} \right) \) and its behavior as \( x \) approaches 0. The graph of this function is provided for visual analysis, and we will address the following parts: (a), (b), and (c).
#### Graph Explanation
The graph illustrates \( \sin \left( \frac{1}{x} \right) \) against \( x \), focusing on the interval around \( x = 0 \).
1. **Axes Labels & Orientation**:
- The x-axis (horizontal) ranges from \( -\infty \) to \( \infty \).
- The y-axis (vertical) ranges from -1 to 1, aligning with the amplitude of a sine function.
2. **Key Features Near \( x = 0 \)**:
- As \( x \) approaches 0, the frequency of oscillations of the sine function increases significantly. This is due to the \( \frac{1}{x} \) term inside the sine function, causing rapid changes in the angle fed into the sine function as \( x \) gets smaller.
- The function appears to oscillate infinitely between -1 and 1 in a very narrow range near \( x = 0 \).
3. **Visible Markings**:
- Specific points are marked on the x-axis corresponding to certain values of \( x \): \( \frac{2}{9\pi} \), \( \frac{2}{7\pi} \), and \( \frac{2}{5\pi} \). These points show where the function crosses the x-axis again as the value of \( x \) increases from zero.
The behavior of \( \sin \left( \frac{1}{x} \right) \) as \( x \to 0 \) includes increasingly frequent oscillations, creating an appearance of a "dense" area on the graph near \( x = 0 \). The function is not defined at \( x = 0 \) because \( \frac{1}{x} \) is undefined there.
### Task Instructions
To fully grasp the function's behavior and implications, follow the exercises in parts (a), (b), and (c)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F50351a65-5e52-4545-9e5a-caf58e03b0d0%2F2a68cd9d-9f74-44ad-8573-d800baf2cb89%2Fobrbj9_processed.png&w=3840&q=75)
