should not enroll in this class if you cannot sit for the final examination at its scheduled time.
Prerequisite: Math 18 or Math 20F or Math 31AH, and Math 20C.
Textbook: Steven J. Leon and Lisette de Pillis, Linear Algebra with Applications; published by
Pearson Education, Inc.
Course Content: Second course in linear algebra from a computational yet geometric point of
view. Elementary Hermitian matrices, Schur’s theorem, normal matrices, and quadratic forms.
Moore-Penrose generalized inverse and least square problems. Vector and matrix norms. Charac-
teristic and singular values. Canonical forms. Determinants and multilinear algebra.
Homework: Problem sets will be posted on Canvas and should be completed by the indicated due
date. Please submit your homework to Gradescope. NO late homework will be accepted. There
will be 8 problem sets, and the lowest score will be dropped.
You will be expected to take them seriously and to write them up neatly. You must NOT copy
or paraphrase solutions from any source.
Midterm Exams: There will be two in-class midterms: the first in Week 4 and the second in
Week 8. The exact dates will be updated. There will be no make-up exams. If, for any reason, you
cannot make it to one of the midterms, you will automatically receive grading option (2).
Grading: The final numerical grade will be computed as the highest of the following options:
Option 1: Homework 30% + Midterm 1 15% + Midterm 2 15% + Final Exam 40%.
Option 2: Homework 30% + Best Midterm 15% + Final Exam 55%.
In addition, you MUST pass the final examination in order to pass the course.
Piazza: We will use Piazza, an online discussion board. It will allow you to post messages (openly
or anonymously) and answer posts made by your fellow students, about course content, homework,
exams, etc. You are strongly encouraged to ask questions and discuss on this platform. Here is the
link.
COVID policies: Please review the campus policies and masking requirements.

Accommodations: Students requesting accommodations for this course due to a disability need to
provide a current Authorization for Accommodation (AFA) letter issued by the Office for Students
with Disabilities (OSD). You should make arrangements in advance to discuss your accommodations
with me no later than the end of Week 3. We will make every effort to arrange for whatever
accommodations are recommended by the OSD.
Academic Integrity: Academic integrity is highly valued at UCSD and academic dishonesty
is considered a serious offense. Students involved in an academic integrity violation will face an
administrative sanction which may include suspension or, in very serious cases, expulsion from the
university.
Name and Gender Pronouns: UC San Diego is committed to supporting its students’ name
and gender preferences. Class rosters provided to your instructor and TAs have students’ legal
names, but we will strive to honor your request to be addressed using a preferred name or gender
pronoun. Please let your instructor and TA know your preferences so that we can make changes to
our records. (Certain university records may be beyond our ability to change, however.)
Equity, Inclusion and Respect: We are committed to the UC San Diego Principles of Com-
munity. To foster the best possible working and learning environment, UC San Diego strives to
maintain a climate of fairness, cooperation, and professionalism.
