This is a rigorous proof-oriented course in linear algebra. Topics include vector spaces, linear transformations, determinants, eigenvectors and eigenvalues, inner product spaces, Hermitian matrices, and Jordan Normal Form.
Prerequisites: Math 241 required with Math 347 strongly recommended.
Required text: Friedberg, Insel, and Spence, Linear Algebra, 5th edition, 608 pages, Pearson 2019.
The 4th edition, published in 2002, is also fine, as any differences in problem numbers will be noted in the assignments. Both the Math Library and Grainger Engineering Library have copies of the 4th and 5th editions on in-library reserve.
Supplementary text: Especially for the first quarter of the course, I will also refer to the free text:
Breezer, A First Course in Linear Algebra, Version 3.5 (2015). Available online or as a downloadable PDF file.
Overall grading: Your course grade will be based on homework (16%), three in-class midterm exams (18% each), and a comprehensive final exam (30%). You can view all of your scores in the online gradebook.
Weekly homework: These will typically be due on Friday. They are to be turned in on paper at the start of the class period. If you are unable to attend due to illness or quarantine, you can email me a PDF single file with a scan of your HW; if using your phone/tablet, please use an app designed for this purpose, such as Abobe Scan (iOS, Android). Late homework will not be accepted; however, your lowest two homework grades will be dropped, so you are effectively allowed two infinitely late assignments. Collaboration on homework is permitted, nay encouraged. However, you must write up your solutions individually and understand them completely.
In-class midterms: These three 50 minute exams will be held in our usual classroom on the following Wednesdays: September 21, October 19, and November 16.
Final exam: The combined final exam for sections B13 and C13 of Math 416 will be held on Monday, December 12, from 8-11am in 1092 Lincoln Hall. If you have a conflict, please email me to arrange for a conflict exam.
Missed exams: There will typically be no make-up exams. Rather, in the event of a valid illness, accident, or family crisis, you can be excused from an exam so that it does not count toward your overall average. I reserve final judgment as to whether an exam will be excused. All such requests should be made in advance if possible, but in any event no more than one week after the exam date.
Cheating: Cheating is taken very seriously as it takes unfair advantage of the other students in the class. Penalties for cheating on exams, in particular, are very high, typically resulting in a 0 on the exam or an F in the class.
Disabilities: Students with disabilities who require reasonable accommodations should see me as soon as possible. In particular, any accommodation on exams must be requested at least a week in advance and will require a letter from DRES.
James Scholar/Honors Learning Agreements/4th credit hour: These are not offered for these sections of Math 416. Those interested in such credit should enroll in a different section of this course.
