Thanks for a lot of the help.

That's to say, I'm not sure how you got from the ODE to the solution in the answer.

Oh, I misunderstood, yeah thanks that makes sense. Although I'm still not quite sure how you derived the equation. Did you by any chance use an app like Maple or MATLAB to solve it? Sorry for asking too many questions, my lecturer says it's better to understand how the equation is derived.

Why does the output fall off? Wouldn't $y_{out}$ be higher when in phase with $f_n$

It's fine, I'm an (mechanical) engineering student myself and just needed to be sure.

Thanks. Would you mind explaining how the equation is derived and what $j$ is? It's not $\sqrt(-1)$, is it?
