## Question:

Using the method of Laplace Transform solve the given IVP

{eq}\displaystyle y'' - 2y' + 2y = \cos t; \quad y(0) = 1, \quad y'(0) = 0 {/eq}

## Laplace Transform to Solve IVP:

A linear differential equation with initial conditions given can be solved by using Laplace transform method.

The differential equation in time domain gets converted into an algebraic equation in frequency domain.

This equation can easily be solved using rules of algebra and the time domain solution can be found using inverse Laplace transforms.
