What are the steps of solving an ODE by the Laplace transform? In what cases of solving ODEs is the present method preferable to that in Chap. 2? What property of the Laplace transform is crucial in solving ODEs? = Explain.
16 Νοε 2022 · This section is the table of Laplace Transforms that we’ll be using in the material. We give as wide a variety of Laplace transforms as possible including some that aren’t often given in tables of Laplace transforms.
first- and second-order equations, followed by Chapter 5 (the Laplace transform), Chapter 6 (systems), Chapter 8 (nonlinear equations), and part of Chapter 9 (partial differential equations).

Inverse Laplace transform is calculated with the command invlaplace ( f (s),s,t): f (s) denotes the function to be transformed, s is the independent variable of the function, t is the variable of the transformed function.
