Math 41 Autumn 2014 

Problems from the textbook and other handouts will serve one of two purposes in Math 41: as uncollected Daily Discussion Problems
or as graded Weekly Homework.
Each is handled in a different way and has a different purpose.
About Daily Discussion Problems (Quick Jump to List):
Each time we cover a topic, we will list below the corresponding text section and also some "discussion problems" that
will help direct the discussion in the upcoming Tuesday/Thursday section meetings. Some may be similar to problems
from weekly homework assignments, and problems from prior years' exams will give you an idea of the level of exam
questions. You should try working these discussion problems immediately after reading the book section(s) being covered
in lecture. For complete understanding of the course material, be sure that you understand both the discussion
problems and the weekly homework problems, in addition to all examples from the readings. (Work on daily discussion
problems will not be collected.)
About Weekly Homework (Quick Jump to List):
Completing homework assignments is an essential part of this course. Problems are designed to reinforce concepts covered
in lecture as well as to encourage students to explore implications of the results discussed in class. Very few students
will be able to go through the entire course without struggling on many problems, so do not be discouraged if you do not
immediately know how to solve a problem. In confronting difficult questions you should consider how the problem at hand
connects to topics, definitions and/or theorems discussed in class.
When you have worked on a problem for a while and remain stuck, you are encouraged to ask for hints from your instructor or TA. Students may also discuss problems with one another, but must write solutions on their own. In particular if you have taken notes while discussing homework problems with friends or instructors, you must put these notes away when writing your solution. The Honor Code applies to this and all other written aspects of the course. Be warned: watching someone else solve a problem will not make homework a good preparation for tests. Don't get caught in the trap of relying on others to get through homework assignments.
 Students are expected to take care in writing their assignments. For instance,
 never forget to put your name, your section number and your TA's name on the top of your work;
 assignments should be written neatly;
 assignments should contain clear, complete solutions; and
 completed assignments which contain multiple pages should be stapled for easy grading  one point will be deducted for not doing this.
 For a guide to solution completeness, see this handout of sample writeups for homework and exam problems.
Partial progress toward solutions on problems will be awarded partial credit, but simply writing answers down without justification will receive zero credit. Please note that usually only a portion of each week's problems will be scored; the selection of problems chosen to be graded will not be announced in advance.
Logistics for Weekly Homework:
Assignments must be turned in to your TA (discussion section leader)  you will not receive credit for work turned into another section leader.
The deadline is the beginning of your discussion section on the given due date, and no late homework will be accepted under any
circumstances. (This is as much a courtesy to the grader as an incentive to stay current with the course and not fall behind.)
To accommodate exceptional situations such as a serious illness, your lowest homework score will be dropped at the end of the quarter.
Solutions will be posted on this page.
Students are encouraged to pick up their graded homework assignments promptly; please make arrangements with your TA to pick it up
outside of class (or via electronic scan if absolutely necessary) if you cannot attend the discussion section on the day the
homework is returned. It is ultimately your responsibility to look over your graded assignment while consulting the posted solutions,
not only to check your understanding but also to find any grading errors or mistyped entries in your
CourseWork grade record. If you find an error in how an assignment was graded or
recorded, please appeal to your section leader (who has final authority on all homework appeals). If more than a week has passed
since an assignment was returned in section, your CourseWork score entry for that assignment can no longer be changed.

 Getting started:
 Read the Section Assignments to determine which discussion section you should attend starting Tuesday. Note: you cannot use Axess to sign up for a discussion section, only a lecture. You must use CourseWork to make your discussion section choice  and the chart on the page linked above will show you the options for times.
 Look at the Course Schedule. Make sure you know when the three exams are (not during the lecture time
or in the regular classroom) and when the weekly homeworks are due. If you have a conflict with one of the two midterm exam times,
contact us as soon as you know about it. (The final exam's date and time cannot be changed.)
 Look over the course web page and get to know what information is
there. Read all the General Information on the home page
(including the section "About this class") and
the About homework section above so you know the course policies and logistics.
 Look at the links at the very bottom of the course home page and follow the suggestions there about reading those pages.
