Hi folks,
I have a differential equation which looks like
[tex]sin(f) + \frac{1}{Q}\frac{d(f)}{dt} + \frac{d^2(f)}{d t^2} = g(t)[/tex]
Now for Q << 1 this should, according to our lecture, simplify to
[tex]sin(f) + \frac{1}{Q}\frac{d(f)}{dt}}{d t^2} = g(t)[/tex]
Why that?
I mean, obviously for Q<<1, 1/Q >> 1. But why do we negelct only [tex] \frac{d^2(f)}{d t^2}[/tex]?derivator
