Math 20F Schedule and Homework

Review vectors, dot products, lines, and planes from your calculus course as soon as possible.

Approximate Lecture Schedule. Check for changes.
Since I have not used this text before, schedule is likely to change.
It is IMPORTANT to read the material BEFORE the lecture.

Math 20F Lecture Homework (due in section)

Policy on discussing homework No late homework

Homework is an important part of learning mathematics.
You should get help on problems you are not able to handle.

Due to limited grader resources, only some problems will be graded.
The decision will be made after homework is due, so you should do all exercises.
To receive credit for an exercise, you must show your work.
Solutions to some exercises are in the back of the book, but usually not the work.

Due 1/11:
Sec. 1.1 #7, 12, 18, 23, 24
Sec. 1.2 #5, 13, 14, 15, 16
Sec. 1.3 #9, 17, 22
Sec. 1.4 #1, 6, 8, 21, 22
Due 1/18:
Sec. 1.5 #1, 3, 8, 14, 26, 27, 28

Exam Wed. 1/26 in lecture (Center 119) thru homework sections due on 1/25 (most of Ch.1 and Secs. 2.1 & 2.2). old exams
There will be some computation on the exam; however, the emphasis is more on understanding concepts, especially matrices.
Bring a blue book.
Closed book. No calculator. You may have one page of notes, written on one side.
Q: What do you mean by "concepts"?
A: Examples of concept questions are (a) writing a system of equations in matrix form and (b) knowing when you can add (or multiply) two matrices.
Q: Will we need to know definitions and theorems?
A: Yes and no --- you won't be asked any definitions or theorems, but
(a) You will need to know what a term means if it mentioned on the exam; e.g., if you are asked to find the free variables, don't expect to be told what free variables are.
(b) You may need to use a theorem to do something; e.g., if you are given the inverses of A and B and are asked to calculate the inverse of AB.
Q: Will I have to give a proof?
A: There may be a short proof; e.g., Prove that if A, B and C are square matrices and AB=CA=I, then B=C.
Q: What does "e.g." mean?
A: It's an abbreviation for the Latin "exempli gratia", which means "for example". (Unlike some languages, e.g. German, which abbreviates native words, English normally uses Latin abbreviations such as e.g., i.e., etc. and op. cit., and the Latin word idem.)
GRADE GUIDELINES: This is intended only as a rough guideline. Your course grade will be based on combining the points on the exams and homeworks, appropriately weighted.
A range: the interval (34,38] by mistake, only 38 points on exam
B range: the interval (27,34]
C range: the interval (20,27]
20 or below: D/F range

You should understand why the answers to Supplementary Exercise #1 (p.370) are what they are (see back of the book).
For 3/1: (no more homework is due. "For" is material that you should be familiar with for the final exam.)
Sec. 5.5 #2, 7, 14, 23, 25
Sec. 6.1: 1, 8, 9, 13, 16, 17, 19, 20, 28

Exam Wed. 3/2 in lecture (Center 119) thru Section 5.4 and since material covered on last exam. old exams
Bring a blue book.
Closed book. No calculator. You may have one page of notes, written on BOTH sides.

OPTIONAL FINAL EXAM When you receive your second hour exam back, in addition to the point total there will be a letter grade. This is the grade you will receive in the course if you decide not to take the final exam. This grade will be based on an adjusted weighting since there is no final points to include. The "bad day" allowance will not be taken into account if the final is not part of your grade. If someone has been excused from tests for health or other reasons, their exam will indicate that they must take the final.
"Not taking the final" means not handing in the final. In other words, you have three options:
(1) Don't show up at the final and simply get the indicated grade marked on your second hour exam.
(2) Show up at the final but don't hand it in, again getting the indicated grade.
(3) Take and hand in the final, in which case the final grade will be combined with your other material to determine your course grade.
For 3/8: (no more homework is due. "For" is material that you should be familiar with for the final exam.)
Sec. 6.2: 1, 7, 17, 23, 24
Sec. 6.3: 1, 13
Sec. 6.4: 1
Sec. 6.5: 1, 17
Sec. 7.1: 12, 24, 25(a-c), 29, 35

The final exam is in the lecture room (Center 119) from 8-11 on Tuesday 3/15. Bring a blue book and a sheet (both sides) of notes. You're responsible for all sections that had homework, including the 3/8 homework. If you take the final but decide NOT to hand it in, it is as if you did not take the final---your grade will be the grade that has been given out as your grade without the final. If you hand in the final, it will be graded and will count. If you are looking for additional problems to do to review for the final, look at problems that emphasize concepts rather than calculations since the final will have more conceptual problems than calculations.
