** Dates of exams/dealines: **

Final: March 20, 3-6

Midterm: 2/15

Quizzes: 1/24, 2/7, 2/28, 3/14

Homework to be turned in before beginning of your section on: 1/17, 1/31, 2/14, 2/21, 3/7

Matlab: to be turned in in regular section on Tuesdays. First matlab assignment due on 1/24.

** Matlab** Matlab sections are on Thursdays at the same time as your
regular section. All the sections are in the CLICS Windows Mezzanine
Lab. CLICS is in Revelle, next to Revelle Plaza and York Hall. The lab is
upstairs by the windows. There are two separate labs there, so you
should look for the lab where WENZL 20F is written on the whiteboard.
Matlab assignments
need to be turned in ** in sections**.
Moreover, there will be a short quiz in each section, with the problem
taken from the homework assignments, or being a slight variation
of a homework problem. There are NO make-up quizzes,
but you may drop the worst score of your quizzes.

** Course material:** We will use
the book `Linear Algebra with Applications', 3rd edition, by David C. Lay.
For a tentative syllabus for the course click below.

This course will also include MATLAB problems. You can find the MATLAB assignments at

** Homework assignments **

for 1/16 :: Section 1.1: 10, 12, 20 (`consistent' means that the system has at least one solution, `inconsistent' that it has no solution), Section 1.2: 10, 12, 24, 30

for 1/24 (quiz) :: Section 1.3: 10, 14, 18, 22, Section 1.4: 12, 18, 26,(if you would like to see solutions: do the odd-numbered problem just before the given one - it (usually) is of exactly the same type) Section 1.5: 11, 23, 33, 35,

for 1/31:: Section 1.6: 6, need not turn in problem 10 originally posted here: too messy calculation), Section 1.7: 6, 14, 22, 28, 32, Section 1.8: 4, 16, 20, Section 1.9: 4, 8, 18.

for 2/7 (quiz) :: Section 1.9: 21, Section 2.1: 5, 9, 22, 27, Section 2.2: 7, 13, 31, 35, Section 2.3: 5, 21

for 2/14:Section 2.3: 38, Section 2.5: 10, 18 Section 4.1: 6, 12, 14, Section 4.2: 6, 12, 14, 22, 28

for 2/21:There was a misprint in the original posting as far as the section numbers were concerned. Here is the correct posting: Section 4.3: 4, 8, 16, 20, Section 4.5: 4, 8, 14,

for 2/28 (quiz):Section 4.4: 3, 7, 17, Section 4.6: 3, 7, 13, 21, Section 4.7: 1, 9, 13

for 3/7:Section 3.1: 10, 22, 38, Section 3.2: 8, 20, 34(you can use Prob. 31), Section 3.3: 4, 24 Section 5.1: 8, 16, 26

for 3/14 (quiz):Section 5.2: 5, 11, 19, Section 5.3: 5, 9, 13, Section 6.1: 11, 13, Section 6.2: 3, 9, 21

relevant for final:Section 6.3: 3, 9, 13, Section 6.4: 3, 9, 17ab, 18ab, Section 6.5: 1, 9, Section 7.1: 13, 17(use that the eigenvalues are given), 25ab

**Final** Essentially the same conditions apply as for the midterm.
You are allowed to use one handwritten cheat-sheet, regular size, both sides
OK if you think you need them. The material will be mostly taken from after
the midterm. Basic notions such as linear independence, span etc have also
occurred in problems after the midterm. So you definitely need to know them,
even though we first dealt with them before the midterm.

**Location:** Students in Maia's sections please go to Center 105.
The other students will have the final in our class room

Practice final: Below you can find problems given in previous exams,
based on a slightly different book. IGNORE problem 3, and replace problem
8 by: Apply Gram-Schmidt to the **row** vectors of the matrix in problem 8.
For problems 9 and 10, you may assume V to be R^n, and for 7 you may assume
L to be a linear transformation.
Additional problems may be similar to the ones of the last assignment,
such as calculating the distance to a subspace,
orthogonally diagonalizing symmetric matrices or finding a least square
approximation.

**Office hours for exam week:** William Alto: Saturday, 11-1, (for office
and email see above) Maia Averett: Sunday 4-5 (for office
and email see above), Monday 11-12 in my office, APM 5256.

** Midterm:** The midterm will take place on February 15 in class.
You are allowed to use one hand-written cheat sheet (normal size), but
no calculators, books or other notes. The material will go until
the last homework assignment, due on 2/14. The problems will be
similar to homework problems. To give you some idea, below is some
sample exam.
