Course Description: Linear algebra is a subject that
permeates almost all of mathematics, both pure and applied. For example,
calculus is based on approximating arbitrary functions
by linear maps, which are easy to analyze. This simple idea makes
linear algebra fundamental to algebra, analysis, geometry, physics,
and statistics.
Your primary goals in the course should be to understand
linear algebra from a rigorous point of view and to learn to write
clear and precise proofs.
Material to be covered: Vector spaces, linear transformations,
determinants, inner product spaces, orthogonal and unitary
transformations, diagonalization, dual spaces. You should have
seen much of this material from a computational point of view.
Familiarity with complex numbers is also required.
Homework will be due each week, usually on Friday,
and returned the next week
in discussion. There will be no makeup or late homework accepted,
but the lowest two homework grades will be dropped.
Homework 1. Due Friday, October 2.
Homework 2. Due Friday, October 9.
Homework 3. Due Friday, October 16.
Homework 4. Due Monday, October 26.
Homework 5. Due Friday, October 30.
Homework 6. Due Friday, November 6.
Homework 7. Due Friday, November 13.
Homework 8. Due Monday, November 23.
Homework 9. Due Wednesday, December 2.
Midterm Exams: We will have two midterm exams.
The dates are Friday, October 23 and Friday, November 20.
There will be no makeup exams.
Review for Midterm 1.
Sample Midterm 2 (from Spring 2014).
Final Exam: The final exam is on Monday, December 7, 2015
from 3 PM to 6 PM.
You must take the final to pass the class! If you have a documented
reason that you are unable to take the final, you will receive an Incomplete.
Course outline: My plan is to cover sections 2.1-4,
3.1-5 and 3.7, 6.2, 6.4, and 8.1-5 in the book by Hoffman and Kunze.
Grading: Grades will be assigned based on the higher of the following two
schemes:
10% homework + 25% first midterm + 25% second midterm + 40% final
10% homework + 35% (best of two midterms) + 55% final
- 10/23 - First midterm exam.
- 11/11 - Veterans Day holiday. No class.
- 11/20 - Second midterm exam.
- 11/26-27 - Thanksgiving holiday. No class.
- 12/7 - Final exam. The final will be cumulative.
Evaluation:
- Every exam will include at least one problem taken from the homework,
possibly with minor variations.
- Part of the homework grading will be based simply
on whether you hand in the problems (without copying from someone else).
However, at the top of each homework,
you may mark a problem you wish to be read carefully.
We will read that problem carefully and give you detailed feedback
so that you can get better and better at writing solutions.
- It is your responsibility to know how to do the problems.
Practicing that is the only way to study for the exams.
- A grade of 'F' will be assigned to any student who misses the final. Incompletes are reserved for those who have completed all of the work for the class, including both midterms,
but who, for a legitimate, documented reason, miss the final.
- Exams (or copies) will be returned, but I will keep
copies (or originals) of the exams, as required by the math department.
