Piazza
signup link We will use piazza for communication. If you have questions about any of the material, or any of the homework problems, please post them to piazza. (You can post anonymously, if you like.) Please answer questions posed by your fellow students. It is OK to edit each other's answers to improve them. Please be careful to assign your questions and discussions to the correct folder. Ask your question on piazza, rather than emailing the instructor. 
The Textbook
Author: Klaus Jänich Title: Linear Algebra Series: Undergraduate Texts in Mathematics Publisher: SpringerVerlag Year: 1994 An electronic copy of the textbook is available at the UBC Library. We will follow the textbook closely, and will hopefully cover it completely. The homework problems will be taken mostly from this book. Other books: Author: Paul R. Halmos Title: FiniteDimensional Vector Spaces Series: Undergraduate Texts in Mathematics Publisher: SrpingerVerlag Year: 1974 This is a classic book, which covers the material in much greater depth than is possible in a onesemester course. If you are interested to go further, this book is recommended. The library has an electronic version. Author: Charles W. Curtis Title: Linear Algebra, an introductory approach Series: Undergraduate Texts in Mathematics Publishes: SpringerVerlag Year: 1974 A more elementary book than Halmos, and with more detail than our official textbook. It may be a good supplementary text. The library has an electronic version. 
Math 223 vs. Math 221
Math 223 is the honours version of Math 221. There is a large overlap in material covered in the two courses, but Math 223 is significantly faster, harder and more theoretical. Math 221 teaches you problem solving techniques, Math 223 puts the emphasis on theory, and you will be expected to write formal proofs. In Math 223 we cover additional subjects, and go into more depth than 221. Homework problems in Math 221 are mostly routine, whereas problems in Math 223 will require independent thought and hard work. If you are interested in an applied subject matter, Math 223 is not for you, you should be taking Math 221. You can switch down from Math 223 to Math 221 even after the initial 2 weeks add/drop period, althouth this requires permission of the undergraduate chair, and is ultimately subject to the Dean's approval. The earlier you switch down to Math 221 the better. 
Marking
Your mark will be based on homework assignments, two midterm exams and one final exam, weighted as follows:
The performance of this section in Math 221 level problems on the final exam will be used to scale up the marks of the whole section, so that, on average, you will not be penalized for taking the more difficult Math 223, rather than 221. Still, if you are having trouble with Math 223, you should switch down to Math 221 in order to avoid getting lost, in which case the rescaling will not help you. 
Exams
The midterm exams are scheduled as follows:
No makeup exams will be given. If you miss a midterm due to a valid emergency, your final exam will count for 65% of your grade. 
Adjustments for Covid Response
Because the university closed on the day of the second midterm exam, the second midterm exam does not count towards your grade. Per directions from the Faculty of Science, your final exam will count for 30% of your grade. To reach 100%, the contributions of the first midterm and the homework will be doubled. Thus, the new grading scheme is:
You will be expected to sign a pledge that you will take the exam by yourself, without any outside help, and without the help of computers or calculators. You will be allowed to use your notes, formula sheets, and consult the textbook, but you have to sign a pledge that you will use no online sources. These conditions may still be adjusted, but I hope they will are workable. Remember that your homework scores, as well as your final exam scores will be adjusted to account for the higher difficulty of Math 223 as opposed to Math 221.
