If we are given a function f (t) and we want to find a particular solution of the equation d' y dt 3 + 9 dy = f(t) using variation of parameters, then we should look for a particular solution of the following form: O (a) Up(t) = A(t) f(t) + 9B(t) O (b) Up (t) = A + Best + Ce-3t O (c) Up(t) = A(t) sin(3t) + B(t) cos(3t) O (d) Up(t) = A + Bt + Csin(3t) O (e) Up(t) = A(t) + B(t) sin(3t) + C(t) cos(3t)Step by Step Solution
