Description and Goals
The course provides a rigorous and thorough introduction to linear algebra, a subject which is basic to nearly all branches of pure and applied mathematics, with many applications in science, engineering and economics.
The student will learn to read and write proofs of theorems, and develop computational skills. This course is designed to serve majors in mathematics and those engineering and science students interested in a conceptual understanding of the subject.
Textbook
Linear Algebra, by Insel, Friedberg and Spence (4th ed.)
Software
GNU octave is free, open source Matlab-like numerical linear algebra software that is easy to install and use.
Matlab is somewhat bigger, fancier, and not free.
SageMath is a free open-source mathematics software system,
using a python-based language. It is easy to learn, with lots of online documentation.
You are not required to use octave, Matlab, or SageMath but they are useful tools for learning linear algebra.

Homework
The list of homework problems appears below. You should try to solve all of the assigned problems. I will select certain problems to be written up carefully and turned in for grading. You may discuss ideas to solve homework problems with your classmates, but the written work turned in for grading must be entirely your own.

Exams and Grading Policy
There will be 2 class exams each worth 20 points and a final exam worth 40 points. (Check the course calendar for the dates.)
Homework is worth 20 in total. Your grade will be based on the total (out of 100) of your homework score and the
scores on these three exams. The dates of the class exams and final are given in the course calendar. 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 four weeks in advance.
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

Attendance and Late Policy
Attendance is mandatory, except for absences allowed by UF policies. Each 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.
The UF policy on attendance is here: https://catalog.ufl.edu/ugrad/current/regulations/info/attendance.aspx
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.
