4. Please solve the following differential equation.

**Problem 4:**

For each case, find a second-order, linear, homogeneous ordinary differential equation (ODE) with the given pair of functions as its solutions. Then demonstrate that this pair forms a fundamental set of solutions.

**(a)**  
\( y_1 = 2e^{3t} - 5e^{-t}, \quad y_2 = 11e^{-t} \)

**(b)**  
\( y_1 = \cos(\pi t), \quad y_2 = \sin(\pi t) \)

**(c)**  
\( y_1 = e^{2t} \cos(5t), \quad y_2 = e^{2t} \sin(5t) \)

**(d)**  
\( y_1 = e^{3t}, \quad y_2 = te^{3t} \)
