# Differential Equations and Green's Functions

Consider the inhomogeneous differential equation

-u' + u = r(x) on (a,b)

where r(x) is a continuous function on the interval (a,b)

Find the solution to this differential equation in the form

u = integral from a to b (G(x,s) r(s) ds)

and determine G(x,s).
