Question
![### Educational Content: Evaluating the Integral over a Koch Snowflake
#### Problem Statement
Evaluate the line integral:
\[
\oint_{C} \left( \sin(\sqrt{1+x^3}) + 21y \right) \, dx + 121x \, dy
\]
where \( C \) is the boundary of the region \( K(4) \).
#### Definition and Construction of Regions
The sequence of regions \( K(n) \) begins with the following:
- **\( K(0) \):** An equilateral triangle with a side length of 1.
- **\( K(1) \):** Formed by adding 3 equilateral triangles, each with a side length of \( 1/3 \), to \( K(0) \).
- **\( K(2) \):** Constructed by adding \( 3 \times 4^1 \) equilateral triangles with a side length of \( 1/9 \) to \( K(1) \).
- **\( K(3) \):** Constructed by adding \( 3 \times 4^2 \) equilateral triangles with a side length of \( 1/27 \) to \( K(2) \).
- **\( K(4) \):** Formed by adding \( 3 \times 4^3 \) equilateral triangles with a side length of \( 1/81 \) to \( K(3) \).
The evolution of these regions visually resembles the iterative construction of a Koch Snowflake, a well-known fractal.
#### Visual Explanation
- The image shows the progression from \( K(0) \) to \( K(4) \).
1. **\( K(0) \):** A simple equilateral triangle.
2. **\( K(1) \):** Displays a star-like shape where smaller triangles were added to each side of \( K(0) \).
3. **\( K(2) \):** Shows further complexity with additional triangles, increasing the number of edges.
4. **\( K(3) \) and \( K(4) \):** Each further iteration increasingly complexifies the boundary, contributing towards the fractal nature.
#### Further Exploration
The equation suggests further analysis with \( K = K(\infty) \), exploring the properties of the Koch Snowflake, a fractal exhibiting](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F77548912-c51c-4c9d-8b51-f3905a3bec75%2Faa8f2bc7-627e-4754-8dd7-d963df4103da%2Fugxedis_processed.png&w=3840&q=75)
