The Laplace transform of the function f(t), denoted by F(s) or L{f(t)}, is defined

F s f t e dtst( ) ( )= − ∞∫ 0

provided that the integration may be validly performed. A sufficient condition for the existence of F(s) is that f(t) be of exponential order as t → ∞ and that it is sectionally continuous over every finite interval in the range t ≥ 0. The Laplace transform of g(t) is denoted by L g t{ ( )} or G(s).
