Why exponential terms like $\exp (i\omega t)$ make no contribution when averaged over a long time?
In the physics of waves, I often see expressions like
$$A\exp(i\omega t) + f(t)$$
where $A$ is a constant, $w$ is the angular frequency and $f(t)$ is an arbitrary function that depends on time.
It ...
