Description and Goals
Differential equations arise as mathematical models of physical phenomena. Students will learn how differential equations are derived from physical assumptions. They will also study the algebraic and analytical methods for solving a few types of important differential equation where an exact solution is possible, and gain a qualitative understanding of the solutions of equations that cannot be solved exactly.
Textbook
Fundamentals of Differential Equations, by Nagel, Saff and Snider (7th ed.)
You may use other editions of this book but, if you do, you need to be aware that problems may be numbered differently and it will be your responsibility to find the correct list of homework problems.

Exams and Grading Policy
There will be three class exams (worth 25 points each) and a final (25 points). The dates and times appear in the course calendar. All exams, including the final, will take place in the usual classroom Little 125.
The final exam is on Monday, December 9th, 3 p.m.–5 p.m..
No make-up exams will be given except for documented special reasons, such as medical emergencies. Exams can be rearranged for student athletes only if I am notified at least three weeks in advance. It is the responsibility of each student to make sure that he or she is available to take every exam or, in the allowable cases, to inform me as soon as possible so that alternative arrangements can be made.
If you think that a score has been computed incorrectly, please bring the matter to my attention within one day of your work being returned.
If you think that your work has been graded incorrectly, please submit an appeal in writing within seven days of your work being returned, explaining your reasons in detail. Appeals may result in a higher, unchanged, or lower score, depending on the merit of the appeal. Decisions on appeals are final. The final exam cannot be appealed.
Grading Scale
Grades: A=90-100, A-=87-89, B+=83-86, B=78-82, B-=75-77, C+=70-74, C=65-69, C-=60-64, D=50-59, E=0-49
The UF regulations on grades are here: https://catalog.ufl.edu/ugrad/current/regulations/info/grades.aspx
The UF policy on minus grades is here: https://catalog.ufl.edu/UGRD/academic-regulations/grades-grading-policies/#:~:text=No%20grades%20will%20be%20calculated,credit%20is%20awarded%20only%20once.&text=Colleges%20may%20not%20accept%20grade,credit%20in%20the%20same%20field..
Attendance and Late Policy
Attendance is mandatory, except for absences allowed by UF policies. I will check attendance frequently. Each noticed unexcused absence (after you are registered) carries a penalty of 1 point, subtracted from your score after the total (out of 100) has been computed.

Special accommodations
Students with disabilities who experience learning barriers and would like to request academic accommodations should connect with the disability Resource Center by visiting disability.ufl.edu/students/get-started . It is important for students to share their accommodation letter with their instructor and discuss their access needs, as early as possible in the semester.
Honor Code
UF students are bound by The Honor Pledge which states, “We, the members of the University of Florida community, pledge to hold ourselves and our peers to the highest standards of honor and integrity by abiding by the Honor Code.
On all work submitted for credit by students at the University of Florida, the following pledge is either
required or implied: “On my honor, I have neither given nor received unauthorized aid in doing this
assignment.”
The Honor Code (http://www.dso.ufl.edu/sccr/process/student-conduct-honor-code/)
specifies a number of behaviors that are in violation of this code and the possible sanctions.
Furthermore, you are obliged to report any condition that facilitates academic misconduct to appropriate
personnel. If you have any questions or concerns, please consult with the instructor of this class.
Course Evaluations
Students are expected to provide professional and respectful feedback on the quality of instruction in this course by completing course evaluations online via GatorEvals. Guidance on how to give feedback in a professional and respectful manner is available at https://gatorevals.aa.ufl.edu/students/. Students will be notified when the evaluation period opens, and can complete evaluations through the email they receive from GatorEvals, in their Canvas course menu under GatorEvals, or via https://ufl.bluera.com/ufl/. Summaries of course evaluation results are available to students at https://gatorevals.aa.ufl.edu/public-results/
