Laplace Transform: Explaining Theory & Solving ODE

Click For Summary
SUMMARY

The Laplace Transform (LT) is a powerful mathematical tool that converts differential equations (DEs) into algebraic equations, simplifying the process of finding solutions. When applied to second-order ordinary differential equations (ODEs), the LT facilitates easier manipulation and solution. The transformation follows specific rules, allowing for the systematic handling of initial conditions and boundary values. Ultimately, the LT enables the transformation back to the original domain to retrieve the solutions of the DEs.

Hello,

What does laplace transformation exactly 'do'? If I have PDE of second order and use LT on it, what do i get to solve? ODE? or if I have ODE of second order, what do I need to solve afet transformation? How does this work? is there any rule?!

The thing with integral transforms is that they can turn differential equations into algebraic equations which are far easier to solve and then you can transform back to obtain the solutions of your differential equations.
