Math 20F Lecture Homework (due in section)
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
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.
The final exam is in the lecture room (Center 119) from 811 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 finalyour 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.
