MATLAB Quiz Thursday, March 13 Same Time As Your Section (APM B432) Alternate Time Sign Ups Are Online DON’T FORGET!!!! (NO MAKEUPS)

Laplace Transforms “Change of Variables” For Ordinary Differential Equations Need to review 2 ideas from Calculus

Review Topic 1: Improper Integrals An Integral with Infinity In Limit is Called “Improper” Evaluated with a limit Two Behaviors: Converge Diverge Integral Goes To A Finite Constant Integral Goes To

Review Topic 2: Piecewise Continuous Functions A Function is Called “Piecewise Continuous” On An Interval [a,b] if: The interval can be divided into sub intervals,,,… And the function is continuous on each interval And Both exist (BUT DON’T HAVE TO EQUAL) for any

Integral Transform Introducing a “Kernel Function” Now a function of Is Given By An “Integral Transform” of a Function

Integral Transform Introducing a “Kernel Function” “Laplace Transform” Given By,, Is Given By An “Integral Transform” of a Function

Examples “Laplace Transform” Given By,,

Linearity Examples

Questions?

Why Do This? In Calculus, change of coordinates: We Will See That The Laplace Transform will be like a change of coordinates, OD E Algebra Problem
