using Laplace transform to solve initial value problems
Since the Laplace transforms of the derivatives of arepolynomials in the transform parameter (see table of Laplacetransforms), forming the Laplace transform of a linear differentialequation with constant coefficients and initial conditions
at yields generally a simple equation(image equation (http://planetmath.org/imageequation)) for solving the transformed function . Since the initial conditions can be taken into consideration instantly, one needs not to determine the general solution of the differential equation.
For example, transforming the equation
gives
i.e.
whence
Taking the inverse Laplace transform produces the result
