When such a differential equation is transformed into Laplace space, the result is an algebraic equation, which is much easier to solve. Furthermore, unlike the method of undetermined coefficients, the Laplace …To solve differential equations with the Laplace transform, we must be able to obtain \(f\) from its transform \(F\). There’s a formula for doing this, but we can’t use it because it requires the theory of functions of a complex variable. Fortunately, we can use the table of Laplace transforms to find inverse transforms that we’ll need.Find the Laplace transform of the function f(t) if it is periodic with period 2 and f(t) =e^{-t} \ \text{for} \ t \in [0,2).

In mathematics, the Laplace transform, named after its discoverer Pierre-Simon Laplace ( / ləˈplɑːs / ), is an integral transform that converts a function of a real variable (usually , in the time domain) to a function of a complex variable (in the complex frequency domain, also known as s-domain, or s-plane ).It is therefore not surprising that we can also solve PDEs with the Laplace transform. Given a PDE in two independent variables \(x\) and \(t\text{,}\) we use the Laplace transform on one of the variables (taking the transform of everything in sight), and derivatives in that variable become multiplications by the transformed variable \(s\text{.}\)Qeeko. 9 years ago. There is an axiom known as the axiom of substitution which says the following: if x and y are objects such that x = y, then we have ƒ (x) = ƒ (y) for every function ƒ. Hence, when we apply the Laplace transform to the left-hand side, which is equal to the right-hand side, we still have equality when we also apply the ...
