![### Problem 1: Evaluate the Integral
Consider the double integral:
\[
\int_{0}^{1} \int_{-\sqrt{1-x^2}}^{0} 2x \cos \left( y - \frac{y^3}{3} \right) \, dy \, dx
\]
#### Explanation:
This problem involves evaluating a double integral over a specified region. The inner integral is with respect to \( y \), ranging from \( -\sqrt{1-x^2} \) to \( 0 \). The outer integral is with respect to \( x \), ranging from \( 0 \) to \( 1 \).
The integrand consists of the function \( 2x \cos \left( y - \frac{y^3}{3} \right) \), incorporating both the trigonometric cosine function and a cubic polynomial in \( y \). The problem likely requires utilizing integration techniques suitable for such functions, potentially involving substitution or numerical methods, depending on the context.
#### Steps for Evaluation:
1. **Start with the inner integral**: Integrate \( 2x \cos \left( y - \frac{y^3}{3} \right) \) with respect to \( y \).
2. **Proceed to the outer integral**: Once the inner integration is performed, integrate the resulting expression with respect to \( x \).
This problem illustrates a typical application of double integrals, emphasizing the importance of understanding the limits of integration and the integration techniques applicable to the given functions.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F77548912-c51c-4c9d-8b51-f3905a3bec75%2F78fcbdd9-883a-4403-b702-60232ff7e0a5%2F4avqul_processed.png&w=3840&q=75)
