Course Content and Objectives
Differential Equations are ubiquitous in the sciences and engineering. This course is designed to serve students in engineering, physics, mathematics and related disciplines with the aim of understanding qualitatively, applying, and solving ordinary differential equations of the most usual types.
The course starts with an introduction to the concept of differential equations. It covers first order methods, including separability, exactness, integrating factors, first order linear equations, Bernoulli’s equations, and second order equations reducible to first order ones.
The course continues with higher order methods for constant coefficient linear equations including particular solutions by the method of annihilators and undetermined coefficients, as well as the theory of linear ordinary differential equations.
The course also covers Laplace transform methods, including properties of the Laplace transform and solution of initial value problems via the Laplace transform. Series solutions will be covered as time permits.
Some applications, from such areas as mechanics and electrical circuits, will be covered.
Text book
Suggested Problems
Selected problems from the text will be assigned on a daily basis.
Exams.
There will be four mid-term exams, each worth 100 points. There will be no make-up exams, rather a replacement for any one mid-term can be taken at the time scheduled for the final.
- Exam 1. Wednesday 23 September.
- Exam 2. Friday 16 October.
- Exam 3. Monday 9 November.
- Exam 4. Monday 7 December.
- Makeup exams. Wednesday 16 December, 3-4:10pm.
Grading
A course total will be computed by adding the exam scores. Grades will then be assigned according to the scale:
90 A
87 A-
83 B+
80 B
77 B-
73 C+
63 C
57 D
Attendance
Attendance is recommended.
Additional Information:
Grades. Grading will be in accord with the UF policy stated at https://catalog.ufl.edu/ugrad/current/regulations/info/grades.aspx. Also see the current UF policy on assigning grade points.
Academic Honesty. The course will be conducted in accordance with the University honor code and academic honesty policy
UF students are bound by The Honor Code 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 niether given nor received unauthorized aid in doing this assignment.” The Honor Code specifies a number of behaviors that are in violation of this code and the possible sanctions. Furthermore, you are obligated to report any condition that facilitates academic misconduct to appropriate personnel. If you have questions or concerns please consult with the instructor.
Accommodation for students with disabilities. Students with disabilities requesting accommodations should first register with the Disability Resource Center (352-392-8565, https://www.dso.ufl.edu/drc/) by providing appropriate documentation. Once registered, students will receive an accommodation letter which must be presented to the instructor when requesting accommodation. Students with disabilities should follow this procedure as early as possible in the semester.
Online Evaluations. “Students are expected to provide feedback on the quality of instruction in this course by completing online evaluations at https://evaluations.ufl.edu. Evaluations are typically open during the last two or three weeks of the semester, but students will be given specific times when they are open. Summary results of these assessments are available to students at https://evaluations.ufl.edu/results/.”
