1. The problem statement, all variables and given/known data Find a suitable form for the general solution of y'' - 4y' + 4y = 2t2 + 4t*e2t + t*sin(2t) For respective particular solutions, state where it is a general or a special case. DO NOT evaluate coefficents. 2. Relevant equations Y1 = At2 + Bt + C Y2 = (Dt3 + Et2) * e2t Y3 = (Ft + G)sin(2t) + (Ht + I)cos(2t) 3. The attempt at a solution I know the method of undetermined coefficients, and I found the particular solutions. They are right. What does it mean when it asks if a particular solution is of the general or special case? I have no clue.
