Although this topic has already been addressed in multiple popular questions of SE but i have few confusions in this regard
In the top voted answer there was a sentence that i highlighted
If we set the real part of the complex variable s to zero, $\sigma=0$, the result is the Fourier transform $F(j\omega)$ which is essentially the frequency domain representation of $f(t)$
So what does that imply? If Fourier transform is essentially the frequency domain representation of $f(t)$ then does that mean Laplace transform is not frequency domain representation
Link of question
In top voted answer, there was a sentence
Laplace transforms can capture the transient behaviors of systems. Fourier transforms only capture the steady state behavior.
What does that imply? Fourier transform cannot be used for studying the transient behavior and Laplace transform cannot be used for studying steady state behaviour?
One last confusion: Which transform is more commonly used in practial applications ?Laplace transform or Fourier transform?
