Section 1.2: 6d, 8, 15–16 or 19–20 or 22; 7* (7 is interesting to think about but has no answer in the back of the book.)

HW #5  Friday, Mar. 1  Selfchecked problems: (these problems need not be turned in)

We understand that it is presently cold and flu season. If you are contagious, or too tired to get anything out of lecture, you should not come to class. Homework may always be turned in by a classmate or friend in either the 8:35 or 12:55 section of class on Friday (both in KIMP 301), or slipped under my door (SCEN 222) by 1:45 on Friday. If you must submit your homework by email, it must be in my inbox by 1:45 on Friday, and the scan must be clearly legible even after I print it out. (This means (1) don't use a camera, find a real scanner, and (2) write on white paper, not yellow or tan paper.) As a reminder, we will drop your lowest (and probably also your second lowest) homework scores, so if you're too sick to do homework once or twice, it probably won't affect your grade. 
HW #6  Friday, Mar. 8  Selfchecked problems: (these problems need not be turned in)
Section 3.4: 3, 4, 5abc, 7, 11, 15; 8, 10 Section 3.5: 5, 6, 10 Graded problems: (these problems should be turned in) Do problems (AB 15), (AB 16), and (AB 17) in this file. 
A student in your class has requested access to lecture notes. If you are willing to share your notes, consistently, for the entirety of the semester, you may be eligible to receive up to 50 community service hours OR a $50 Amazon gift card. You may sign up by visiting our website (http://cea.uark.edu) and clicking the “NoteTaker” tab found at the top of the page. Please feel free to contact the Center for Educational Access for additional instruction at ceanotes@uark.edu. Thank you.

Instructor  Ariel Barton 
aeb019@uark.edu  
Office  SCEN 222 
Office hours  SCEN 222, Wednesday and Thursday 2:00, or by appointment.
No class meetings or office hours will be held on days when the university is closed due to inclement weather. 
Course Description: Systems of linear equations, vector spaces, linear transformations, matrices, and determinants.
Prerequisites: MATH 2554 or MATH 2043, with a grade of C or better.
Text: Linear Algebra with Applications, 9th Edition, by Steven J. Leon.
Course grade: Here is how I plan to weigh your grades:
Homework  20% 
Midterm tests  15% each 
Final  35% 
Cell phones: Cell phones, tablets, laptops, and other electronic devices may be used in class. The expectation is that these devices will be used for taking notes, routine calculations (i.e., calculator apps), accessing course materials, and other courserelated uses only. Please do not text or play games in class!
Tests: There will be three midterms tests and a final exam. I plan to hold midterm exams during class time on the dates indicated in the calendar above. The final exam will occur in our regular classroom at the time indicated on the registrar's website.
If you require accommodations on an exam, notify your instructor as soon as possible, but in all cases at least one week before the exam is to be held. Documentation from the CEA may be required, depending on the nature of the accommodation.
Makeup exams: Makeup exam requests also require written documentation as to your conflict. Except in the case of medical or other unforeseen emergencies, makeup exam requests must be made at least one week before the exam is to be held. Makeup exams are at the instructor's discretion; if you do not provide a documented reason why you cannot take the exam at the usual time, if your reason is considered inadequate, or if your request for a makeup exam is not made in a timely fashion, I reserve the right to refuse a makeup exam or to assess a late penalty (deduction from your score).
Makeup exams will be taken in the Mathematics Testing Center maintained by the MRTC. You will be allowed to take your exam on the scheduled exam date at any time when the Testing Center is open. You must finish your exam before the Testing Center closes; it is your responsibility to arrive early enough to allow this to happen.
Homework: Assignments will be posted to this website. Each week you will be assigned a number of selfchecked problems and a smaller number of graded problems. You may ask anyone for help with your homework, but you must write up your solutions on your own.
Graded problems should be turned in for grading at the start of class on the due date.
If you cannot make it to class on the day homework is due, you may:
Selfchecked problems will not be graded and need not be turned in. You will be able to check your answers by looking at the answers given in the back of the book. It is important that you do these problems; you will learn the material much better if you practice it by doing all problems, and material covered only on selfchecked problems and not on instructorcorrected problems will still appear on the midterm tests and final exam.
I expect to have 11 assignments over the course of the semester; your lowest score (or two scores) will be dropped.
Incompletes: Only given in extreme circumstances, and only when the student has satisfactorily completed all but a small portion of the work in the course. Students must make prior arrangements with the professor well before the end of the semester.
Academic Integrity: All students will be bound by and should familiarize themselves with the university's academic integrity policy.
