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.). You can also use the 5th ed., in which case see the changes noted in the homework section.
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 In general, these problems are for practice
and do not have to be turned in. The homework part of the grade will be based on assignments to to be turned in for grading, which may include some of these
problems. You may discuss ideas to solve homework problems (including graded ones) with your classmates, but the written work turned in for grading must be entirely your own.The numbers for the 5th ed. of the text are mostly the same, and changes are noted in the form (5:6, 7:8) to indicate that Q5 and Q7 in the 4th ed. became Q6 and Q8 in the 5th ed.

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
