1. Consider the general linear second-order ODE
Poy" +P1y' + P2y = −
(1)
where po, P1, and p2 are functions of x and A is a constant parameter. The standard
form of the Sturm-Liouville ODE
(py')'+ qy = -Awy,
where p, q, and w are functions of x and A is a constant parameter.
(a) Assuming that po, P1, P2, and à are given, multiply Eq. 1 by w. By
comparing to Eq. 2, show that the unknown p, q, w, λ must satisfy p =
= wp1, 9= wp2, and λ = A.

(b) Show that p= exp(fdx).
(c) Show that w = exp(fdx).

This shows that a general linear second-order ODE can, in principle, be put into the
standard form of the Sturm-Liouville ODE.
2. For each of the ODEs below, find the weight function w(x) that will allow the
ODE to be written as a standard Sturm-Liouville ODE. Also give the resulting ODE
