*. The two part final is scheduled for Tuesday 14th, 1:30 to
4 PM. However, I have another final scheduled from 10:45 to 1:15, so I'll be
trying to see if we can move our exam later by half an hour or so.

** Pre-requisites**: Passage of ELM and/or Intermediate
algebra and trigonometry (Math 109 or Math. 70 and 107, or equivalent high
school courses.). High School physics or Physics 101/102 strongly recommended.
Some knowledge of using a scientific calculator.

__Text- Required:____ __*Physics*, by J.S. Walker (Prentice Hall,
2002) This is the same text as used by Physics 111. I understand there is a new
edition, so be sure to get the one being used for the Phys 111 course if that
is where you are headed. If you are heading for 220, you still need to get
access to a cop of *Walker.* Look for a used copy of the old edition.
Since the problems you do will be at WebAssign (see below), you really don't
need the current text. There isn't that much difference between the two.

** AND** you have to register for Webassign. - it costs $10 to
register. Go to webassign.net. You should be recognized, although
I don't have all the latest adds there yet. It costs $10; pay by credit or
debit card. This is an on-line homework site. It has the problems from Walker
that I will assign. You should find you have 3 attempts on a problem before you
need to submit you work for grading. It tells you whether you got the question
right or wrong on each try, and after the due time it gives you the solution.
It also shows me how many tries you made and so enables me to be able to review
your work. I really don't have the time to grade individual homework and to
give feedback, so WebAssign should be of great benefit to both of us! To sign
on, your user name is your first initial and last name (for instance, mine is
rrogers), the institution is sfsu, and your (temp) password are the 5

In addition, I'll be
referring you to http://www.sosmath.com: an excellent on-line math tutorial
site

__Optional: __*Schaum's Outline of Precalculus* by Fred Safier

__Optional: __I've
tried a number of different specialized books to directly address the needs of
these classes, but I've not had good luck. Two that I've used and which I will
list as optional are

__Cole__,* So You Want To Take Physics (Algebra and Trig) *Saunders,
1993

__J Celesia__, *Preparation for Physics *Brooks-Cole (an alternative
approach to Cole, rather idiosyncratic. Especially good for study techniques.
It really works for some, not for others (I love it, but it doesn't have enough
problems or exercises to practice on.))

(A BIG problem with both of these is that they are relatively expensive!)

As indicated, I am not
requiring the Schaum's Outline book listed above. It's useful, but I think the
SOSMath.com site gives as much, if not more. Some of you may want another book
that goes over elementary math concepts in more detail (the web site and
Schaum's are *reviews,* not instructional texts). One I've used in the
past is Prindle and Prindle: *Math The Easy Way* (Barron). However, the
trouble with most of the books other than the Schaum's is that they don't have
any trigonometry review, a big part of what we will be doing. The SOSMath.com
does have the trigonometry, however, another big plus for it.

__Objectives/Outcomes:__

- Be able to use basic pre-calculus mathematics to
solve exercises involving exponents, scientific notation, trigonometric
functions, and solution of simple equations
- Be able to work with 2 dimensional vectors and
to apply them to simple physical situations
- Be able to discuss the major concepts of mechanics
covered in the first 6 chapters of the texts used in Physics 111 or
Physics 220.
- Be able to solve elementary mechanics questions
related to the work covered in C.

__Homework and Course
binder__: The primary
homework source will be WebAssign: the problems from

I will also ask for a
weekly personal journal email report from you in which you detail what you have
done and accomplished during the past week, the problems you have finished and
where you may have had particular problems or sticking points. While I have a
minimum objective for coverage, I base much of the schedule on your feedback.
Please send me these weekly emails by Tuesday whether I remember o ask you to
or not.

There also will be
occasional in-class quizzes, to check on requireed progress. After the first
few weeks, however, it becomes impossible to give quizzes for the whole class
due to diffeent rates of progress.

You should keep a homework
binder with all your work including class notes, worked out problems, along
with reading notes, questions, etc. This binder will be your __one__
reference for the final (I promise most of the final will be taken from
material you should have in your notebook), and the binder ought to be of great
help to you in the intro physics course you will take next. Remember, the way
you learn to solve complicated problems is by solving simpler related problems.
That's where the notebook is important. By reviewing and becoming familiar with
problems you have solved, you become able to solve more complicated problems.
And if you are taking Phsics 111 next, you will find a number of the problems
you do here will also be assigned in that class.

This is a 3-unit class,
which means that you should be spending **at least **6 hours a week outside
of class on it. If you do less, you are shortchanging yourself in term of what
can be a positive learning experience

__On your written work __-

__Grading and Final Exam:__ This semester grading is for a
letter grade. (In the past it has been for CR/NC only) For me to give a grade
of B or better I have to be convinced that you are ready to move on to either
Phys 111 or Phys 220 (depending on your calculus background). The grade will
depend on two parts: math skills, and physics problem solving ability. The
greater part of the grade will be based on your physics solving ability.
However, in order for that to show up as part of your grade you will ** have
to **master the math skills which will be tested in the math prelim part
of the final.

__Setting personal
objectives and feedback: : __Initially I’ll ask you to commit to a schedule which indicates the time
you intend to spend on this course, and your specific learning goals. I’ll also
ask for a weekly email feedback as to how you are adhering to your schedule and
what material is giving you particular difficulty. This is in lieu of my
conducting regular individual meetings, but I also strongly encourage you to
come in to talk to me about how and what you are doing as the semester
progresses.

__Outline and indication
of work that will be covered__. The outline below is a suggested course of study. However,
since I'll only be seeing most of your work via WebAssign, you can certainly
deviate from this.

** Math review**:

Past semesters I have tried
a variety of review texts, such as the Schaum's Outline series. This semester I
am going to try an excellent on-line, free math tutor, found at
http://www.sosmath.com/. This will be largely a self-tutor. You should work out
problems and keep them inn your binder to show me. The tutor really only needs
to be worked through if you need the review and drill, but I’m guessing, based
on past experience, that all of you would gain by going through it.

1. Start with **Fractions**.
This is so basic and so important to master in detail; I suggest you work your
way all the way through, but I’ll ask you to be sure to do problems from each
section until you understand. SoSmath gives you 29 rules; make sure that you
know each one perfectly!

- Rule 1: Zero in the Denominator of a Fraction,
Rule 2: Zero in the Numerator of a Fraction, Rule 3: One Minus Sign in a Fraction, Rule 4: Odd Number and Even Number of Minus Signs in a
Fraction, Rule 5: Division Symbol in a Fraction, Rule 6: Properties of the Number 1, Rule 7: Different Faces of the Number 1, Rule 8: Any Integer can be Written as a Fraction, Rule 9: Factoring Integers, Rule 10: Reducing Fractions, Rule 11: Multiplying Two Simple Fractions, Rule 12: Multiplying an Integer and a Simple Fraction, Rule 13: Multiplying Three or More Simple Fractions, Rule 14: Dividing Simple Fractions, Rule 15: Dividing a Simple Fraction by an Integer, Rule 16: Dividing Three or More Simple Fractions, Rule 17: Building Fractions, Rule 18: Adding Two Simple Fractions, Rule 19: Subtracting Two Simple Fractions, Rule 20: Order of Operations for plus, minus, times, division, Rule 21: Order of Operations for Parentheses, Rule 22: Order of Operations for Nested Parentheses, Rule 23: Order of Operations in Fractions, Rule 24: Converting Complex Fractions to Simple
Fractions, Rule 25: Multiplying and Dividing Two Complex Fractions, Rule 26: Adding and Subtracting Two Complex Fractions, Rule
27: Compound Fractions, Rule 28: Converting Decimals to
Fractions, Rule
29: Converting Percentages to Fractions

** Units of
conversion"**
is the next section in

Skip

Finally (and one of the real troublemakers for most) will be the

And that's it for the Algebra review section.

__Trigonometry:__

This is the one other math
review section we consider. We are only interested in learning how the
definition of the trigonometric functions and how to use them to calculate
lengths of the sides of a right triangle, given one side and one angle (for **any
angle through 360 degrees or 2 pi radians**). You also need to learn to be
able to quickly calculate an angle of any vertex of a right triangle, given the
lengths of any two sides. Also, we want to recognize the "special
triangles" - the 45 -45-90, the 30-60-90, and the "3-4-5" and we
want to know how to use radian measure. This means going through the **Angle
Measure** section and the first part of the **Trigonometric Functions**
section. We need to get through these trig section prior to (or coincident
with) Chapter 3 of Walker. We may need to skip around to be able to do this. In
addition, this is where one must learn to use your calculator, both in degree
and radian measure of angles. Come to see me during office hours for additional
help on this.
