The discussion focuses on solving the second-order ordinary differential equation (ODE) given by y'' + 2y' + y = f(t) with initial conditions y(0) = 0 and y'(0) = 0. The function f(t) is defined piecewise, being equal to 1 for 0 < t < a and 0 for t > a. The solution approach involves using the integral representation y(t) = ∫G(t,t') f(t') dt' with integration bounds from 0 to infinity, where G(t,t') is the Green's function associated with the ODE.
PREREQUISITESThis discussion is beneficial for undergraduate students studying differential equations, particularly those seeking to understand advanced solution techniques and applications of Green's functions in solving second-order ODEs.

y'' + 2y' + y = f(t); y0=y0'=0
f(t) is piecewise -- 1 for 0 < t < a; 0 for t > a
Use
y(t) = ∫G(t,t') f(t') dt' with bounds 0 to infinity
2. The attempt at a solution
I don't really have any logical attempt. My highest math is diffy q 1, Calc 3 and LA 1, I can't find a single resource (besides the 2 pages in my textbook) that addresses this topic in language that I understand.
