This is a very basic question but I'm confused about the way we represent a signal in frequency domain.
Let's say I have a cosine signal in time domain : v(t)=5cos(2*pi*1000*t)
In frequency domain, why do we get a graph like this?
**broken link removed**
I know that our signal has amplitude of 5 at 1k Hz, but representing our circuit that way, we don't know anything as the frequency change.
why don't we represent it like we do in time domain?
ex. v(t) : as t change we know the amplitude on y-axis
V(f) : as f change we know the amplitude on y-axis
Like this

I'm very confused because when we do a "Bodeplot" we draw the second graph(as f change we see how a circuit behave) it is also in frequency domain.
What really is a frequency domain????
Thank you so much!
