Laplace Transform of Derivatives. For first-order derivative: L{f′(t)} = sL{f(t)} − f(0) L {f ′ (t)} = s L {f (t)} − f (0) For second-order derivative: L{f′′(t)} = s2L{f(t)} − sf(0) − f′(0) L {f ″ (t)} = s 2 L {f (t)} − s f (0) − f ′ (0) For third-order derivative:
Differentiation and the Laplace Transform. In this chapter, we explore how the Laplace transform interacts with the basic operators of calculus: differentiation and integration. The greatest interest will be in the first identity that we will derive.
