  1. 24 Μαΐ 2024 · ONE OF THE TYPICAL APPLICATIONS OF LAPLACE TRANSFORMS is the solution of nonhomogeneous linear constant coefficient differential equations. In the following examples we will show how this works. The general idea is that one transforms the equation for an unknown function \(y(t)\) into an algebraic equation for its transform, \(Y(t)\).
