Syllabus: This course is an introduction to ordinary differential equations. The topics covered in this class are

Prerequisites are Math 131-132.

Text and online homework: We will use the textbook Elementary Differential Equations, 11th Edition (2017) by William E. Boyce, Richard C. DiPrima, Douglas B. Meade. An electronic copy of the textbook is integrated in the homework system Wiley-Plus that we will use for the class. When setting-up your account with Wiley plus there will be an option to purchase a hard copy of the book for a (small) extra-fee.

Grading and Exams There will be one midterm exam (worth 1/3 of your grade) common to all sections and a final exam (worth 1/3 of your grade) common to all sections. Homework are assigned weekly and done on-line on WileyPLUS

Weekly Schedule

The following is meant to give a general idea of which sections are covered in which weeks and may be adjusted as needed. All the sections will be covered.
As a general principle the material in a given week will be subject of the homework due the week after to leave you time to review the material.
