MA 238 Differential Equations Learning Objectives

Understand the definition of a differential equation and the meaning its solution as well

as statements of existence and uniqueness theorems

Be able to solve first order differential equations and apply their solutions

- Separable Equations

- Integrating Factor methods

- Homogeneous Equations

- Applications:  Population models (exponential growth), radioactive decay, Newton's

Law of Cooling (exponential decay), acceleration-velocity models, motion in a resisting

medium. Higher order d.e.'s (mostly 2nd order).

- Homogeneous equations with constant coefficients: general solution.

- Non-homogeneous equations: particular solutions; methods of Undetermined

coefficients and

Variation of Parameters

- Applications: Equations of Motion; Simple Harmonic Motion.

First-order linear systems. Introduction to matrix and operator techniques.

Laplace Transform methods, use of Transform Tables. Wave Functions.
