  <statement>
    <p>Explain how to find the particular solution to each given IVP.</p>
    <ol>
      <li>
        <me> -{x''} - 4 \, {x} = 0 \hspace{2em}
           {x} (0)= 1 ,

      </li>
    </ol>
  </statement>
  <answer>
    <me> {x} = \cos\left(2 \, t\right) + 4 \, \sin\left(2 \, t\right) </me>
    <me> {y} = -2 \, e^{\left(-3 \, t\right)} + e^{\left(-4 \, t\right)} </me>
