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.
