   1. The idea. We turn our attention now to transform methods, which will provide not just a tool for obtaining solutions, but a framework for understanding the structure of linear ODEs. The idea is to de ne a transform operator L on functions, L : origin space ! transformed space. such that the ODE in the transformed space is much easier to solve.

   SUMMARY OF THE LAPLACE TRANFORM. The Laplace Transform of a function f ( t ) , t ≥ 0 is defined as. ∫. ∞. L − f ( t ) ≡ f ( s ) ≡ e st f ( t ) dt , 0. where s ∈C , with Re ( s ) sufficiently large for the integral to converge. The Laplace Transform is a linear operation.

   The Laplace Transform is a critical tool used in the theory of diferential equations with important applications to fields such as electrical engineering. Despite its many applications, the transform is mathematically rich, leading to several important theorems considering its behavior on diferent functions and its own structure.

   What is a Laplace transform?

   • At its heart, the Laplace Transform is an integral transform, which itself has its set of unique properties, such as its actions on diferent functions. In addition, the transform, moving between the time and frequency domains and thus between real and complex numbers, has an inverse transform due to its uniqueness, which itself can be studied.

   What is inverse Laplace transform?

   • a complex-valued function. As mentioned in Theorem 2.4, the Laplace Transform is unique. As such, we can define the Inverse Laplace Transform as taking, as an input, a complex valued function F which is the Laplace Transform of another function f and return the function f.

   Why are Laplace transforms a key tool?

   • Laplace Transforms become a key tool here because, as discussed in Proposition 2.8, the Laplace Transform of a convolution is simply a product of Laplace Transforms. Indeed, for the above convolution, where Y, X and H are Laplace transforms of y, x and h, respectively. In this case, the function H(s) is known as the transfer function.

   Can a Laplace transform transform a differential equation into an algebraic equation?

   • In essence, the Laplace Transform transforms diferential equations into algebraic equations, which are far easier to solve. We discuss another application, which is to evaluat-ing integrals, a more mathematically-oriented application. In particular, Laplace Transform identities can be manipulated to evaluate certain integrals.

   How do you solve a Laplace transform?

   • Let Y (s) = L[y(t)] be the Laplace transform of the solution. Applying L to the equation, we obtain the transformed equation L = L[y0] L [y] = sY y(0) Y: Since L = 0; we get 0 = (s 1)Y y(0); which is trivial to solve! The transformed solution to the ODE is then y(0) Y (s) = : 2. The laplace transform Now we go through the basic theory.
