General Information
Please see Lecture Plan for detailed information.
In person lectures
All lectures will be held in person unless otherwise stated. They will not be recorded. Slides for the lectures are available on CANVAS.

If you are not feeling well or have been instructed to not come to class, please contact the instructor prior to class.
In person and remote office hours
Office hours will generally be held in person except the zoom office hour on Thursday X hour as noted above. Individual appointments with instructors may be held remotely via zoom.
Math 23 tutorial sessions
Tutorial sessions are every Sunday, Tuesday and Thursday from 7-9 pm in Kemeny 108.
Grading
The course grade will be based upon on weekly homework (total 80 points), exam 1 (100 points), exam 2 (135 points), exam 3 (185 points). Total points possible: 500.
Violations of the Academic Honor Principle will be referred to the the Committee on Standards. In particular please be aware of rules regarding plagiarism and collusion.
Exams 450 points
- Exam 1: 100 points: (tentative) Thursday October 7
- Exam 2: 135 points): (tentative) Thursday November 4
- Exam 3 (cumulative final): 185 points: Final exam period begins November 19. Exact date TBD.
Homework 80 points
Homework reinforces concepts and skills while challenging students to extend what they have learned to other types of problems. Because it is important for students to have this experience, instructors will not solve assigned homework problems during office hours before the due date. We will of course answer questions you may have in approaching problems that give you difficulty. It is therefore essential to begin homework sets early so that you may get help if difficulties do arise.
Written homework is assigned weekly and posted on the homework page. It is due each Tuesday before midnight (East coast time). We will be using webwork . As all homework is posted well in advance, no late homework will be accepted. Homework typically covers course material through the previous Friday.
Homework grading policy: The goal of homework is to learn to work through problems. Therefore each problem set will be assigned a grade on a 10 point scale based on the following percentage of correct results as submitted through webwork: 85% or higher = 10; 81-85% = 9; 71-80% = 8; 61-70% = 7; 50-60% = 6; 30-49% = 5; 20-29% = 3; 10-19% = 2; 5-9% = 1; below 5% = 0. The lowest homework score will be dropped, and the combination of the remaining scores will be out of 80 points.
Honor Principle
We will strictly enforce Dartmouth's Academic Honor Principle.
On Exams: Giving and/or receiving assistance during an examination violates the Academic Honor Principle.
On Homework: Collaboration is both permitted and encouraged, but it is a violation of the honor code for someone to provide the answers for you.
Textbook
Elementary Differential Equations and Boundary Value Problems (11th Edition) by Boyce & DiPrima, Wiley 2017. It is fine to use the 9th or 10th edition. The problems may differ at the end of each section, but the content is primarily the same. You may find online versions of some older editions.<\span>
ORC Course description
This course is a survey of important types of differential equations, both linear and nonlinear. Topics include the study of systems of ordinary differential equations using eigenvectors and eigenvalues, numerical solutions of first and second order equations and of systems, and the solution of elementary partial differential equations using Fourier series.
Prerequisite:
Mathematics 13
Disabilities
Students with learning, physical, or psychiatric disabilities enrolled in this course that may need disability-related classroom accommodations are encouraged to make an office appointment to see your instructor before the end of the second week of the term. All discussions will remain confidential, although the Student Accessibility Services office may be consulted to discuss appropriate implementation of any accommodation requested.
