The equation in the image is:

\[
\int_{-2}^{2} \left( x^3 \cos\left(\frac{x}{2} + \frac{1}{2}\right) \right) \sqrt{4 - x^2} \, dx
\]

This is an integral of a product involving a trigonometric function, a polynomial, and a square root. Let's break down the main elements:

1. \( x^3 \) is a cubic polynomial.
2. \( \cos\left(\frac{x}{2} + \frac{1}{2}\right) \) is a cosine function with a linear argument.
3. \( \sqrt{4 - x^2} \) is the square root of a quadratic function.

The limits of integration are from \(-2\) to \(2\).

This type of integral might be difficult to solve directly using elementary functions, and it might require advanced techniques such as numerical integration or approximation methods.
