WebNow we apply the sifting property of the impulse. Since the impulse is 0 everywhere but t=0, we can change the upper limit of the integral to 0 +. Since e-st is continuous at t=0, that is the same as saying it is constant from t=0-to t=0 +. So we can replace e-st by its value evaluated at t=0. So the Laplace Transform of the unit impulse is ...
