Final answer:
The Laplace transform is used to express a differential equation in the s-domain and solve initial value problems.
Step-by-step explanation:
The Laplace transform is used to express a differential equation in the s-domain. In this case, it is used to solve the initial value problem. The Laplace transform allows us to transform a differential equation into an algebraic equation in the s-domain, where s is a complex variable. By solving the algebraic equation, we can find the solution to the initial value problem.
