### Problem Statement

2. Let \( P \) denote the path that goes in straight lines from \( (1, 1, 1) \) to \( (-1, -1, 1) \) to \( (-1, -1, -1) \) to \( (1, 1, -1) \) and then back to \( (1, 1, 1) \).

Compute \(\int_{P} \vec{F} \cdot d\vec{r}\), where \(\vec{F}(x, y, z) = \left( \begin{array}{c} \frac{2xy + z}{e^{xy} + 2} \\ x^2z + \sin(z) \end{array} \right)\).

### Explanation

- **Path Description:** The problem describes a closed path \( P \) in three-dimensional space. The path consists of straight-line segments connecting the points sequentially: 
  - \( (1, 1, 1) \to (-1, -1, 1) \)
  - \( (-1, -1, 1) \to (-1, -1, -1) \)
  - \( (-1, -1, -1) \to (1, 1, -1) \)
  - \( (1, 1, -1) \to (1, 1, 1) \).

- **Vector Field:** The vector field \(\vec{F}(x, y, z)\) is given with components:
  - First component: \(\frac{2xy + z}{e^{xy} + 2}\)
  - Second component: \(x^2z + \sin(z)\)

- **Line Integral Task:** The task is to evaluate the line integral of the vector field \(\vec{F}\) along the path \( P \). The line integral \(\int_{P} \vec{F} \cdot d\vec{r}\) involves integrating the dot product of the vector field \(\vec{F}\) and the differential path vector \(d\vec{r}\) along the closed path \( P \).
