(07/01 - 8:30am) I have just written the final. Here is some info about it:
(06/29 - 9:40am) I will leave town shortly after our final. My plan is to grade your exams on Thursday afternoon and submit the grades on the same day. If you need or want to see me, it must be on Friday! (Likely around 11am, but we can try to figure out a time, as long as I can meet everyone who wants to see me in a small interval.)
(06/29 - 9:35am) Unfortunately, I might not be available for office hours on the day of our final (07/02). I will have to leave town the day before and I might not be in town until noon or so.
I will try to get here as soon as possible, but more likely it will be around 12:30pm. If you want to come, between 12:30pm and 1:30pm, write me an e-mail! If I don't get an e-mail until 9am, I will just not hurry and take my time to come back to town. (Keep in mind that even if we make an appointment I might be late. It's a doctor's appointment, and you know how this things can run late...)
I strongly recommend that you start studying early and come to office hours on Wednesday instead of Thursday, though. The exam will be one hour and a half long, so I will not take questions in the first half hour as with the midterms.
I apologize for the inconvenience, but there was no alternative.
(06/10 - 11:30am) My office hours are now MWTh from 11 to 12. This way you can come the day of the exams to ask questions.
(05/20 - 12:00pm) Please, check this section often. I will put announcements and important info here.
(05/20 - 12:00pm) Please, hit the ``Refresh'' or ``Reload'' button on your web browser every time you visit this page, so that you can see the most recent updates.

Textbook: H. Anton, ``Elementary Linear Algebra'', 9th Edition. Wiley, 2004. (The ``Applications Version'' of this book is also OK, but more expensive and unnecessary.)
Prerequisite: Math 142 or Math 148.
Class: MTWThF 1:30pm to 3pm at HBB 103. (Section 1.)
Exams: Midterms: 06/11 (Thu) and 06/25 (Thu), in regular classroom and time; Final: 07/02, also in our regular classroom and time.
Grade: 25% for quizzes/HW + 20% for each Midterm + 35% for the Final. Note the weight of the Quizzes/HWs!

Here is the Midterm I and the Midterm I with solutions.
The exams were graded and will be returned in class on Friday (06/12). (You can check your grades in Blackboard.) If you are not in class that day, you have to come by my office to pick up yours. (I will not take them to class anymore.) The average was 81.5, the median was 86 and the highest grade was 100. The grades were divided among very good grades (above 80) and pretty bad (below 60). This exam should be considered an easy one.
I usually post a curve, but I will not this time. People below 60 would like get D's or less, while people above 80 would likely get B's and above.

Here is the Midterm II and the Midterm II with solutions.
The exams were graded and will be returned in class on Friday (06/26). (You can check your grades in Blackboard.) If you are not in class that day, you have to come by my office to pick up yours. (I will not take them to class anymore.) The average was 72.7, the median was 78.5 and the highest grade was 92. The results of the exam, as expected, were not as good as the previous exam.

Here is the final: Final, Final Solution.
Back to the TOP.
Firstly, this is a summer course, in which 16 weeks are squeezed into 5. So, as you can imagine, the pace is quite fast. You cannot just ``catch up on the weekends'' in a course like this, as by then we will have covered way too much material. You should catch up immediately if you fall behind, as you will not be able to follow classes and things just start to accumulate in a faster pace than you will likely be able to catch up. I strongly recommend that you review, do problems, and study every day.
This is a first course on Linear Algebra. We will study matrix algebra, system of linear equations, vector spaces, linear transformations, and eigenvalues/eigenvectors.
The first two of these topics are of computational nature, while the latter topics will be more theoretical, and hence usually considered harder by the students. Therefore, the initial plan is to go rather fast through the computational material, so that we can go over the most challenging topics on a better pace.
We will likely cover the following:
The first three chapters will be covered in a faster pace. Chapter 4 might also be covered superficially and briefly. The last three chapters should be the more challenging ones, I hope to have enough time to cover them in a slower pace.
Also, note that this outline is subject to change slightly without prior notice.
Homeworks will be assigned after every class and the selected problems and due dates will be posted at the section Homework of this page. No paper copy of the HW assignments will be distributed in class. It is your responsibility to check this page often! Besides HW assignments, other important information will be posted here. (Check the section Important Notes often!)
The HWs will be due Mondays and Thursdays, when you will either turn in your HW or take a quiz on problems taken directly from the HW set due on that day. In the former case, two or three problems will be graded and count the same as a quiz. In the the latter, the HW will not be collected at all. You will not known in advance if the HW will be collected or if there will be a quiz, and hence you should be prepared for either one.
The quizzes will take place at the beginning of the class. You will not have extra time if you are late. You will have only ten or fifteen minutes to take a quiz, and so if you hadn't already solved the HW problems, you might not have enough time to come up with a solutions.
Points will be taken from messy solutions in all assignments, and you need to show work in all questions (unless stated otherwise)! (This same applies to quizzes, HWs, exams and all graded work!)
Calculators will not always be allowed! I've given in the past the students the option of using calculators in second part of the course, but due to how this would affect the exams, they have always chosen to not use them. So, I decided to just take the ``no calculators'' policy from the beginning. (This includes HW, quizzes, and exams!)
I will do my best to post solutions to the most difficult problems. If I do, they will be posted in this page.
In my opinion, doing the HW is one of the most important parts of the learning process, so the weight for them is greater than the weight of a single midterm, and I will assume that you will work very hard on them.
Also, you should try to come to my office hours if you are having difficulties with the course. I will do my best to help you. Please try to come during my scheduled office hours, but feel free to make an appointment if that would be impossible.
Finally, it is your responsibility to keep all your graded Quizzes, HW, and Midterms! It is very important to have them in case there is any problem with your grade. You can check all your scores at Blackboard. (Blackboard will be used only for scores. This is the official site for the course.)
There will be no make-up quizzes or exams. If you miss a quiz or exam and have a properly documented reason, your final will be used to make-up your score.
You will have to check your e-mail at least once a week, preferably daily. I will use your e-mail (given to me by the registrar's office) to make announcements. (If that is not your preferred address, please make sure to forward your university e-mail to it!) I will assume that any message that I sent via e-mail will be read in a week or less, and it will be considered an official communication.
I have an On-line Feedback Form where you can anonymously send me your comments and suggestions. I will consider your comments and try to do whatever I can to resolve possible problems before it is too late. So, please, feel free to use it whenever you have any constructive comment or suggestion. (In fact, I would greatly appreciate it.) If you don't want you comments to be anonymous, just send me an e-mail or come by my office and we can discuss the problem.

Academic Integrity
Study, preparation and presentation should involve at all times the student's own work, unless it has been clearly specified that work is to be a team effort. Academic honesty requires that the student present his or her own work in all academic projects, including tests, papers, homework, and class presentation. When incorporating the work of other scholars and writers into a project, the student must accurately cite the source of that work.
All students should follow the Honor Statement: from Hilltopics 2008/2009, pg. 11:
Honor Statement
``An essential feature of The University of Tennessee is a commitment to maintaining an atmosphere of intellectual integrity and academic honesty. As a student of the University, I pledge that I will neither knowingly give nor receive any inappropriate assistance in academic work, thus affirming my own personal commitment to honor and integrity.''
You should also be familiar with the Classroom Behavior Expectations.
Students with disabilities that need special accommodations should contact the Office of Disability Services and bring me the appropriate letter/forms.

Please read: I will try to post here a few solutions. The new solutions will be added to this same file. They might come with no explanation, just the ``answer''. If yours do not match mine, you can try to figure out again. (Also, read the disclaimer below!) You can come to office hours if you want explanations for the answers. Be careful that just because our ``answers'' were the same, it doesn't mean that you solved the problem correctly (it might have been a ``fortunate'' coincidence), and in the exams what matters is the solution itself. I will do my best to post somewhat detailed solutions to the harder problems, though.
Disclaimer: I will have to put these solutions together rather quickly, so they are subject to typos and conceptual mistakes. (I expect you to be a lot more careful when doing your HW than I when preparing these.) You can contact me if you think that there is something wrong and I will fix the file if you are correct.
