• Midterm 1 Sample
Solutions
Corrections: In question 2 I added incorrectly in the last row operation. The correct final answer is (-1,1-2). Also, in question 1 I should have written "pivot position" rather than "pivot."
• Midterm 2 Sample
Solutions
Correction: In problem 2, the output of the transformation should have been (a0,a1,a2) rather than (a1,a2,a3). I have fixed this in the version that is currently posted.
• Sample Final
Solutions
Correction: In problem 7, the entries of v3 need to be permuted.

## Resources

• We have a discussion forum on Piazza. This is a good place to ask questions of each other and the TA's. You can learn a lot by answering other peoples' questions as well. It is shared with some of the other sections of Math 18.
• Audio from lectures is recorded, and is available as a podcast.
• Lecture notes will be posted online.
• There are many words in this class that you will need to understand, so we have a vocabulary list.
• The Supplemental Instruction (SI) program holds study groups focussed on solving problems, and led by an experienced undergraduate. Our SI leaders are Lana Andreasyan (landreas) and Kevin Dam (kqdam). Here is the meeting schedule.
• OASIS organizes linear algebra tutoring as well
• MyMathLab provides review quizzes for every chapter. They were compiled by the authors of the textbook, not by me, so they sometimes cover topics that we will skip in this course. Nonetheless they are good practice. They will not affect your grade in any way.
• The math department provides drop-in MATLAB tutoring. See here for the schedule.
