Math 100 - Sections 02 and 05 - Fall 2022
Subject to change.
Welcome to Linear Algebra! I’m looking forward to meeting you all and starting our work together. Please let me know if you have any questions at all, about our course or anything else.
Linear algebra and its elementary applications. Topics: Matrix algebra; simultaneous linear equations; linear dependence and vector spaces; rank and inverses; determinants; numerical solution of simultaneous linear equations; linear transformations; eigenvalues and eigenvectors; unitary and similarity transformations; quadratic forms. This is a 3 unit class.
Students should have successfully completed Calculus 2 (e.g. Math 26B or Math 31) with a grade of C- or better before taking this course. If you have any questions or concerns about this prerequisite, please check in with me as soon as possible.
In this course, students will (1) increase their capacity for critical thinking and fact-based reasoning, (2) develop the necessary competency with the concepts and mechanics of basic linear algebra for further work in mathematics and other fields, and (3) improve their communication of mathematics. Specific content outcomes are to

We will have regularly scheduled online homework—the main goal of these is to build comfort and confidence with the core techniques of the course. You are allowed and encouraged to collaborate with your classmates (and with me!) on solving the problems. Although you will enter your answers online, please make sure that you carefully organize your solutions and all supporting work on paper to help prepare for the exams.
We will be using the free system WeBWorK. For more information and the link to log in, please see the course website.
Our class will benefit greatly from the perspective, questions, and comments of each student. I will try to make space for various ways to bring your voice to our class, but your grade for this component will based our your attendance. Please let me know if you need to miss class, and I’ll be happy to discuss excusing the absence.
There are 2 midterm exams. They are tentatively scheduled for Oct. 07 and Nov. 18. There is also a Final Exam:
Overall grades for the course will be determined from the course components listed above with the following weighting:
The maximum cutoff for letter grades will be: A- 90%, B- 80%, C- 70%, D- 60%, F 59–0%.
Please come to class as much as possible! Our community will benefit greatly from a breadth of perspectives, and class will provide an opportunity to ask, clarify, and answer questions. I will also take attendance for you participation grade. Please send me a quick email if you need to miss class, so I know what is going on and can support you getting caught up.
Please strive hard to meet the deadlines, but if you need an extension for any reason, I am always happy to discuss it with you. Health related reasons will always be accommodated. Please send me a quick email as soon as you realize that extra time is needed—I really want you to be successful! Although late assignments may be subject to a reduced grade, I will usually grant short extensions with no penalty.
