## Homework Statement

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.
