Worksheet Questions

You can print the PDF. This worksheet is about Heaviside functions and solving IVPs with the Laplace transform.

  1. Write an expression for the function $f(t)$ shown below using Heaviside functions. In your final answer, all terms should be in the form $u_c(t) g(t-c)$ for some $g$, such that the Laplace transform is easy to compute.
