(d) Now choose values for b and c so that the coefficients in the equa- tion from (c) do not contain y or t separately, but may contain n up to the first power (some coefficients may just be constants). (e) Propose a solution for f of the form f = Ae-9, plug this into the differential equation for f from part (d), then pick values of q and a so that the equation is satisfied.
