# Homework Help: Nonhomogeneous PDE with Delta Function

1. The problem statement, all variables and given/known data
The problem seems to be straight forward:
y''-$$\lambda$$2y=$$\delta$$'(x-z)
with 0<x<L and 0<z<L along with the boundary conditions: y(0)=y'(L)=0

3. The attempt at a solution

I've tried to follow the notes that my teacher laid out for us during class, but I'm not completely sure I'm doing the problem correctly. Mostly I'm concerned with how I've derived the y1 and y2 equations along with the determinant and constant findings. If somebody could explain how the determinant of these matrices helps find the solution, it would be much appreciated.

Thank you
