**Problem 7: Resonance in Undamped Systems**

Consider the following system, where the motion has no damping and the solution \( y(t) \) is affected by resonance:

\[ y'' + 4y = 3 \cos 2t, \quad y(0) = 1, \quad y'(0) = 0. \]

1. **Determine the Solution \( y(t) \):** 
   - Find the solution for this initial value problem.
   - Identify both the homogeneous and particular nonhomogeneous solutions.

2. **Analysis of Solutions:**
   - Consider the homogeneous and particular solutions.
   - Check if the homogeneous solution exhibits exponential decay.
   - Evaluate whether the steady-state solution is bounded.
