Laplace (Higher Order)

Transforming derivatives into algebraic powers of s generalizes perfectly.

1

Introduction

Just like , higher derivatives follow a pattern.

Worked Examples

Example 1: 3rd Order IVP

.

.

.

.

Inverse using Partial Fractions.

Example 2: 4th Order Beam

.

.

Often used for beams with point loads (Dirac deltas).

Example 3: Discontinuous Forcing

Laplace is ideal for .

Just add to the RHS.

Variation of parameters would be a nightmare here.
