Module for the Laplace Transform Solution of an O. D. E.
Numerical Methods for O. D. E. using Mathematica. (c) John H. Mathews, 2003
Background.
Laplace transforms are useful in solving initial value problems for ordinary differential equations and systems of ordinary differential equations. In this exercise we explore the method of using Laplace transforms. First load Mathematica's built in "LaplaceTransform" subroutine package.
Example 1. Use Laplace transforms to solve the initial value problem
with
.
Solution 1.
Example 2. Use Laplace transforms to solve the initial value problem
with
,
and plot the solution over the interval
.
Solution 2.
Example 3. Solve the initial value problem
with
.
Solution 3.
Example 4. Use Laplace transforms to solve the initial value problem
with
,
and plot the solution over the interval
.
Solution 4.
Example 5. Use Laplace transforms to solve the initial value problem for the system of D.E.'s
