In this course we do elementary linear algebra.
This is mainly about solving linear equations in a more
abstract or formal way. It would be more so, in a honors class.
General Organization and Navigation:

Course Delivery: The course delivery would be via Zoom. There will be no
inperson meeting. However, this is not to be mixed up with so called onlinecourses. There is regular class meeting time for this class.

Comments on Teaching: I have been a proponent of Online Teaching methods, particualrly at this level. Even before COVID I uploaded every bit of information on my website.
Whenever I thought something is worth mentioning, I added that to my lecture notes.
Most of us are used to the idea that we are being taught by teachers.
I believe, at the end, we teach ourselves, by reading the matrials provided by the instructor, and working out homework. In this internet age, there are alternatives to inclassinstructions.
This being a honors course, coming to classes is important. I am assuming, you are taking a honors course, because you are interested in deeper insight. A professor says a lot of things, and communicates emphasis that cannot be written down entirely.
Sometimes, you would trigger a discussion, that may take the class to an unplaaned direction.
Given the circumstances, you are in good hands. Come to classes,
read the materials, workout the HW problem. I provided solutions to many HW problems, look at them (only) if you are stuck.
 You woud do the following
 Read the Lecture notes.
Sometimes, I may provide additional
guidence on certain sections.
We will cover 4 sectons each week, on an average.
 Submit Homework, by email (photo copy or pdf),
by the
due date.
I will inform you of the due dates by email, (or by updating the site).
 Solutions to some HW are available, on left side link.
 Navigation:
All the links you need to navigate are on the left side.
 Exams: You would take three takehome exams (may not be 100 points each).
Exams would be made
avaiable well ahead of when due.
 Calculator: An advanced calculator (TI84) will be of great
help.
 You would receive further instructions via emails, as needed.
Textbook:
We will use a combination of the following:
 We wll mainly use my Lecture Notes
 In case we use any other resources, updates
would be available through this site.
Material to Cover
 Chapter 1 : System of linear equations
 Chapter 2 : Matrices
 Chapter 3 : Determinants
 Chapter 4 : Vector spaces
 Chapter 5 : Eigenvalues and eigenvectors
 Chapter 6 : Inner product spaces
 Chapter 7 : Linear transformations
Grading Scheme:
Homework 
50 

Total HW points will be prorated to 50 points.
 Feeling comfortable with homework would be the key.

Grades will be calcualted in two ways:
 Including Homework, out of total of 350 points
 Without Homework, out of total of 300 points
 You will be given the lower of the two. For example,
to get
an A, you would need to get A in both ways.
