Exercise 4.3.1 For each ODE in parts (a)-(w):
• Find a general solution un(t) to the homogeneous version of the ODE.
• Use the method of undetermined coefficients to find a particular solution up(t) to the
nonhomogeneous ODE. This answer is not unique.
• Write out a general solution to the nonhomogeneous ODE and use it to obtain initial
conditions u(0) = 2 and u' (0) = 3.
