Chapter 1.3, Problem 7P

Show that Eq. (10) can be matched to each equation in Problems $7$ through $12$ by a suitable choice of $n$, coefficients $a_0,a_1,a_2,\mathrm{...},a_n$, and function $g$. In each case, state whether the

equation is homogeneous or nonhomogeneous.

$\frac{dQ}{dt}=-\left(\frac{1}{1+t}\right)Q+2\sin t$
