MATH 226

Differential Equations

Assignment 4

Due Monday, February 28

Read Section 2.2: “Linear Equations: Method of Integrating Factors” and Section 2.3: “Modeling with First Order Equations”

Problems

Part I: Section 2.1: Separable Equations

For the starred(*) problems, use the dsolve and odeplot functions in Maple to plot the solution and verify the solution you obtain by hand. You can copy the file Assignment4.mw from the Handouts Folder for MATH0226 in Spring 22 in the Classes folder on middfiles. I’ve entered the differential equations for Problems 13, 16, and 17.

Practice Problems 2.1: 1, 3, 7, 12, 13*, 16*, 17*, 21, 29, 33

Feedback Problems 2.1: 16, 29, 33

Part II: Section 2.2: Linear Equations: Method of Integrating Factors

For the starred(*) problems, use Maple for drawing direction fields.   See the example in Assignment4.mw

Practice Problems 2.2: 1*, 4*, 7*, 8*, 13, 15, 22*, 25*, 31, 35, 36, 38, 41

Feedback Problems 2.2: 4*, 22*, 36

Part III: Introduction to MATLAB

Begin working on the problems/exercises in Intro to MATLAB by Professors Crodelle and Kubacki. You can link to the handout via our course website. Complete the activities by Wednesday.
