Introduction to the Laplace Transform and Applications
www.sjsu.eduLaplace Transform in Engineering Analysis Laplace transform is a mathematical operation that is used to “transform” a variable (such as x, or y, or z in space, or at time t)to a parameter (s) – a “constant” under certain conditions. It transforms ONE variable at a time. Mathematically, it can be expressed as:

Laplace Transforms for Systems of Differential Equations
www.math.usm.eduThe Laplace Transform of a System 1. When you have several unknown functions x,y, etc., then there will be several unknown Laplace transforms. 2. Transform each equation separately. 3. Solve the transformed system of algebraic equations for X,Y, etc. 4. Transform back. 5. The example will be first order, but the idea works for any order.
