### Problem 5: Solve the Initial Value Problem

Solve the initial value problem given by the differential equation:

\[ y'' + y = f(t) \]

with initial conditions:

\[ y(0) = 0, \quad y'(0) = 1 \]

where the function \( f(t) \) is defined as:

\[ 
f(t) = \begin{cases} 
1 & \text{if } 0 \le t < \frac{\pi}{2} \\ 
0 & \text{if } t \ge \frac{\pi}{2} 
\end{cases}
\]
