**Exercise 22**

Solve the following inhomogeneous differential equations. Give the general solution and then apply the conditions:

a. \( \ddot{y} - 4\dot{y} + 3y = t \);  
   Initial conditions: \( y(0) = 1 \), \( \dot{y}(0) = 0 \).

b. \( \ddot{y} - 4y = 2 \cos t \);  
   Initial conditions: \( y(0) = 0 \), \( \dot{y}(0) = 0 \).

c. \( \ddot{y} + 4\dot{y} + 3y = 4e^{-t} \);  
   Initial conditions: \( y(0) = 0 \), \( \dot{y}(0) = 2 \).

d. \( \ddot{y} + 2\dot{y} + 6y = 3t \sin 2t \);  
   Initial conditions: \( y(0) = 1 \), \( \dot{y}(0) = 2 \).
