### Problem Statement:
Find the solution in the form of Fourier integrals for the following partial differential equation:

\[ u_t - 3u_x = 0, \]

subject to the following conditions:

1. \(|u(x, t)|\) is bounded as \(x \to \pm\infty\),
2. \(-\infty < x < \infty, \quad t > 0\).

and the initial condition:

\[ u(x, 0) = 
   \begin{cases} 
      \sin x & \text{for } x \in [0, \pi], \\
      0 & \text{for } x < 0 \text{ or } x > \pi.
   \end{cases}
\]
