Question
Let us think about the previous part in a little different way. You are
-2t and you want to produce a second unknown
u(t)y1(t) for a
certain function u(t), and hence we just need to determine u(t) in order to determine
given one solution of (1), yi =
solution y2 by using it. Suppose the new solution has the form y2
Y2.
To find out u(t), substitute y2(t) back into equation (1), do calculation, simplify,
and solve for u(t) (you are supposed to have a family of choices). Last, choose a
suitable u(t) for y2(t) and then justify whether y1 and Y2 that you chose form a
fundamental set of solutions. (Compare you results to the previous part)
