ORC Course Description: This course is a survey of important types of differential equations, both linear and non-linear. 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.
Prerequisites: Math 13.
Textbook: R. Boyce and W. Di Prima Elementary Differential Equations and Boundary Value Problems 11-th edition
Written homework will be assigned after each lecture. The written homework assignment can be found here. All homework will generally be due by Canvas on Wednesday following the week when it was assigned, unless announced otherwise.
Late homework will not be accepted unless it is excused in advance for serious reasons. Unexcused late and missing papers count zero.
Honors Code: Collaboration on Homework is permitted and encouraged but NO COPYING. On exams NO HELP given or received and no calculators. In general, when in doubt, ask before doing. Please see also the Statement of Community Standards and Accountability that explains the Academics Honors Principle.
Consent to Recording: (1) Consent to recording of course and group office hours a) I affirm my understanding that this course and any associated group meetings involving students and the instructor, including but not limited to scheduled and ad hoc office hours and other consultations, may be recorded within any digital platform used to offer remote instruction for this course; b) I further affirm that the instructor owns the copyright to their instructional materials, of which these recordings constitute a part, and distribution of any of these recordings in whole or in part without prior written consent of the instructor may be subject to discipline by Dartmouth up to and including expulsion; b) I authorize Dartmouth and anyone acting on behalf of Dartmouth to record my participation and appearance in any medium, and to use my name, likeness, and voice in connection with such recording; and c) I authorize Dartmouth and anyone acting on behalf of Dartmouth to use, reproduce, or distribute such recording without restrictions or limitation for any educational purpose deemed appropriate by Dartmouth and anyone acting on behalf of Dartmouth. (2) Requirement of consent to one-on-one recordings By enrolling in this course, I hereby affirm that I will not under any circumstance make a recording in any medium of any one-on-one meeting with the instructor without obtaining the prior written consent of all those participating, and I understand that if I violate this prohibition, I will be subject to discipline by Dartmouth up to and including expulsion, as well as any other civil or criminal penalties under applicable law.
Disabilities: Students requesting disability-related accommodations and services for this course are encouraged to schedule a phone/Zoom meeting with me as early in the term as possible. This conversation will help to establish what supports are built into my course. In order for accommodations to be authorized, students are required to consult with Student Accessibility Services (SAS; Getting Started with SAS webpage; student.accessibility.services@dartmouth.edu; 603-646-9900) and to request an accommodation email be sent to me. We will then work together with SAS if accommodations need to be modified based on the learning environment. If students have questions about whether they are eligible for accommodations, they should contact the SAS office. All inquiries and discussions will remain confidential.
Mental Health: The academic environment at Dartmouth is challenging, our terms are intensive, and classes are not the only demanding part of your life. There are a number of resources available to you on campus to support your wellness, including your undergraduate dean (http://www.dartmouth.edu/~chd/ ) and the Student Wellness Center http://www.dartmouth.edu/~healthed ).
