State the Laplace transforms of a few simple functions from memory. 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. When and how do you use the unit step function and

The formula L(f0) = sF (s) ¡ f(0¡) must be interpreted very carefully when f has a discon-tinuity at t = 0. We'll give two examples of the correct interpretation. First, suppose that f is the constant 1, and has no discontinuity at t = 0. In other words, f is the constant function with value 1.
