What is the property of the first derivative of the Laplace transform?
First Derivative
The first term in the brackets goes to zero (as long as f(t) doesn't grow faster than an exponential which was a condition for existence of the transform). In the next term, the exponential goes to one. The last term is simply the definition of the Laplace Transform multiplied by s.
What is time shifting property of Laplace transform?
Hence, it proves that a time shift of t0 corresponds to the multiplication by a complex exponential e−st0 in the s-domain.
