We prove it by starting by integration by parts. The first term in the parentheses goes to zero if f(t) grows more slowly than an exponential (one of our requirements for existence of the Laplace Transform), and the second term goes to zero because the limits on the integral are equal.So the theorem is provenThe Laplace transform and its inverse are then a way to transform between the time domain and frequency domain.
