The Laplace transform of the second derivative of a function is s^2 * F(s) – s*f(0) – f'(0), where F(s) is the Laplace transform of the function itself. This formula arises from the application of the Laplace transform to the second derivative and using the properties of the Laplace transform. It allows the solution of differential equations involving second derivatives by transforming them into algebraic equations in the s-domain.
