Math 225 - Introduction to Differential Equations

Summer 2023 - Matthias K. Gobbert

Detailed Schedule - Last Updated 08/07/2023

This schedule is designed to give you an overview of the material to be covered and is tentative in nature. It is a living document and may be updated throughout the semester.
The chapter and section numbers refer to Stanley J. Farlow, An Introduction to Differential Equations and Their Applications, Dover, 2006.
The numbers HW00, HW01, HW02, etc. in the Class column indicate homeworks "HW" due as PDF upload to Blackboard on that day.
The numbers IQ0, BQ0a, BQ1_01, etc. in the Main Topic column indicate online Blackboard quizzes "IQ" and "BQ" due before that class.
The numbers GQ0a, GQ0b, etc. in the Main Topic column indicate in-class group quizzes "GQ" during that class due as PDF upload.
These numbers in the detailed schedule are designed to show the teaching philosophy and learning techniques associated with each class meeting.
See the Assignments area of the Blackboard site for our course for the precise due dates and times.
