2. Mathcad can transform most functions of an independent variable, typically "t" for time, into the Laplace domain without much difficulty. Time shifted functions, such as u(t-a)f(t-a), need to be treated in two steps. First, obtain the transform of f(t-a) using Mathcad's Laplace transform option. This requires defining a new variable T t-a.

We will also see that, for some of the more complicated nonhomogeneous differential equations from the last chapter, Laplace transforms are actually easier on those problems as well. Here is a brief rundown of the sections in this chapter. The Definition – In this section we give the definition of the
