Exam 2 is Tuesday after Spring Break, March 17. It covers everything to date but emphasizes 3.1 (lines) through 4.5.

Exam rooms are the same as last time (also listed here).

Please look at previous exams to see what it might be like.

There is usually, but not always:

a word problem with distance

percents

a word problem with average percent change (Examples 24, 25 page 241-242), but the subsection of 4.4 on "annunities" (p. 243) will not be on the exam

finding a polynomial through points (3.4 Example 9, 4.2 Example 11)

a line problem that needs point-slope form (the whole section 3.1)

a quadratic formula problem with unusual letters (page 134)

a problem where a square root must be eliminated (pages 222-224)

a problem requiring the use of properties of power functions (table, page 191)

numerous, mostly shorter, problems on other topics from 3.1 through 4.5.

Percents are extremely important. They are mentioned every day in the news and are critical in money matters. If you never need the rest of this course in your life and career, you will still need to grasp percents. Make sure you understand Section 4.4 on percents.

There will be review sessions, open to all M151 students, for each exam. They will be two days before and the day before the exam. For Exam 2 they are Sunday, March 15, at 3:00-5:00 and Monday March 16, 6:00-8:00, both in Wilson room 1-119. You need not stay for the whole session and you may come late. (Wilson is usually locked on Sundays, but you may come to the door on the west side (south end) and get in that way.)

Come prepared to show you have seriously tried the problems you ask about. Do not kid yourself that asking questions on Monday is good preparation for a Tuesday exam. Most of your preparation should have been done long before Monday!

If you did well, congratulations! If you want to do better next time,

1) study two hours outside class for each class hour, on average,

2) use the Math Learning Center for free tutoring,

3) study efficiently with this advice from former students.

As in any college course, your instructor does not have time to cover all the material during class. But the text covers it all. You are expected to read the text and learn from it outside class.

The Math Department had an American instructor of high school math in China (a former MSU grad student) give a talk about high school in China. Here is a Chinese school week at his school.

In Chapter 3, your job is to:

3.1 Change how you think about lines. Learn to use the "point-slope" form and the "two-point" form of lines in preference to the famous "y = mx + b" (slope-intercept) form. Do not simplify to slope-intercept form (unless there is a good reason to). Learn how to use point-slope form and two-point form when the points are given functionally or with letters rather than numbers. Learn how linear interpolation works using the "two-point" form.

3.2 Learn how to "complete the square" of quadratics. Learn that when the square is complete the expression exhibits the location of the graph and its axis of symmetry, which is also visible in the Quadratic Formula. Learn how to apply the Quadratic Formula to solve equations in which the unknown is not "x" or the coefficients are not the usual letters (This is related to a good understanding of "placeholders").

3.3 Learn how the formula for distance in the plane is essentially the Pythagorean Theorem. Similarly, equations of circles are given by the distance formula and the Pythagorean Theorem.

3.4 Learn that quadratics which can be written "ax

3.5 Learn that indirect word problems require you to "Build your own formula" which expresses the operations in the particular problem. Cue words indicate operations you express in your formula. Guess-and-check can help you see the operations you need to put into the formula. Usually we build specialized formulas from components that are well-known basic formulas, so write down relevant basic formulas.

3.6. Learn how to approach problems you don't know how to do! (This is what is called "problem solving.") The key is to begin writing the stated information symbolically (even if you don't, at first, see where it is going).

About Chapter 4. Your job is to:

4.1. Learn the shapes of monomials and the approximate possible shapes of polynomials of degrees 1, 2, 3, 4, etc. Learn how many local extrema they can have and how many solutions a polynomial equation of degree n can have.

4.2. Learn how to factor cubics that factor in integers by using the Factor Theorem and a graph. Learn how the Factor Theorem and a graph makes factoring easy if the expression factors in integers.

4.3. Eliminating a square root by squaring may introduce extraneous solutions. Learn to check for extraneous solutions in any problem where you square both sides. Learn that when the relevant theorem is stated with "if..., then..." there is a risk of extraneous solutions, but if the relevant theorem is stated with "iff" there is not. Learn how to solve the equation "x

4.4. [This might be the most important section of all, for percents appear in every newspaper and percents are used when discussing money, credit, investment, and changes of all kinds.] Learn how percents are used to discuss change using multiplication. Successive application of percentage changes is given by successive multiplications. Learn to avoid addition and subtraction in percent problems. Learn how money grows (the Compound Interest Formula, 4-4-6) and how the APY (= effective rate) is computed. Averages are computed using roots, not division (4-4-8).

4.5 Rational Functions, solving rational equations (by reading their graphs), locations of zeros and asymptotes (vertical [p. 254, box] and horizontal) [the most interesting places], end-behavior model (a technical term, it determines horizontal asymptotes, p. 257, box)

About

If there is something you don't know, or don't know how to do, be sure to study that. There are several levels of algebra, and most of the algebra you previously learned is at a lower level--a level that will not be emphasized on the exam. The exam tests you on higher-level skills--on material newly learned in this course. Make sure you can do the "B" problems.

You are responsible for reading and writing mathematics. On the exam we will state theorems or definitions that you have not seen before and ask you to read them and use them. This is a skill that cannot be picked up in an hour or two. We strongly recommend you learn to read math by reading your text.

On the exam we may ask you to state methods symbolically (as in Section 1.4). This is a reading and writing course and problems on the old exams show you we mean it. If you don't read the text and learn how symbolic mathematics is written, you will have a hard time with the exams. Read in order to learn to read and write.

There are problems you will find hard if you have not put a lot of time in playing with your calculator. You do not develop calculator skills without practicing a lot.

Be sure to bring your graphing calculator with the Quadratic Formula programmed into it.

We have free tutoring all day long in the "Math Learning Center". (The linked page lists hours with a Precalculus instructor. However, the MLC is closed the hour before the exam.)

Exam 1, like previous exams, comes with instructions. It says, "Show clear supporting work on problems with several steps. Algebraic problems that display little or no supporting work will get little or no credit. You do not need to show work on one-step calculator problems. To solve numerical problems guess-and-check is legal unless you are requested to solve them "algebraically.”

Precalculus requires you to change.

This page has links to thoughts about learning. You will be learning for many years. Learn to learn efficiently. Here is some of what is known about how to learn. Links about math and jobs.

This web site has an index.

So true! Read your text! Learning to read mathematics with comprehension is a goal of this course.

Pearls before Swine is a comic strip you can read here:

** Philosophy
of this Course. Read this!**
The world is
changing rapidly. Everyday things like iPads, smartphones, apps,
Facebook, Twitter, and massive multi-player on-line games didn't even
exist 10 years ago. What you need to learn about mathematics is
changing rapidly too. Most of the math you learned in high school can
be done by machines. Most of what students used to learn in a typical
precalculus course or even a calculus course can be done by machines
(for free!) So, if you want to learn something with real value, you
need to think about mathematics differently.

**This course requires you to change your thinking
about math.**

This course is different. It is intended to teach
you things that machines can not do for you. It is designed to teach
you what you need to know
about mathematics at the precalculus level that will make you **capable**
and **valuable**.

Software (like wolframalpha.com -- try it!)
can compute answers to symbolic algebra and calculus problems, if you know how to communicate with
it. So, learning to communicate mathematics to machines is one step.
But the real world does not pose problems in symbols, so another
important step is to learn how to take real-world problems and convert
them to mathematical notation. The term "indirect" in Section 1.1 is
relevant.

In the past math courses emphasized

1) computational skills (because, not many years
ago, computations were done by hand) and

2) facts.

But now if you want to solve an equation, there is
software that can
"do" that type of math problem. Now, everyone knows you can look up
facts on the web. If you can pose a math question well, you can
probably find an app or web page to answer it, **if** you can read
and write mathematics well enough. Nevertheless, there is still a lot
of math to learn.You need to learn how to communicate with your
software, interpret graphs, write and
read mathematics to understand how to formulate questions and
interpret answers. Also, you need to have the right question **come
to mind**, which is a non-trivial skill. We want you to have the
prior knowledge required to think of the right questions and
techniques.

In summary, if all you know are the facts and
computational skills that math classes previously emphasized (in your
school!), you have little **value** to anyone. The best person at
multiplying three-digit numbers can be replaced by a $5 calculator. The
best person at solving symbolic algebra problems can be replaced by
free software on a website! We want to **add value** to you, not
teach you valueless skills.

That is why **this course is different--even from
what it used to be a few years ago**. The world is changing and what
we
teach and what you need to learn are changing too.

1) This course encourages you to use machines to do problems that
are already given in symbols,

2) but, you will not get a lot of credit for being able to do
symbolic problems like you learned to do in high school.

3) The intention is to help you develop essential concepts,
abilities, and interpretation skills required to apply math to the real
world and do things machines won't do for you.

4) You will learn to have the right things "come to mind". (It is
one level of learning to know an answer when prompted, another to have
it come to mind without prompting.)

5) Exams will focus on concepts and skills you need to develop,
not on solving problems that machines can solve for free.

6) The point is to add value
to you (knowing how to solve for *x* in problems posed in symbols
is no longer a valuable skill -- sorry!)

7) Reading and writing math forces you to focus on essential,
valuable, mathematical concepts.

8) Expect exams to be quite different from math exams you have
taken before (even different from previous exams given in this class!)
If you have read your text closely, written symbolic math daily on
homework, and assimilated the concepts covered in the text, you will do
well. However, if all you can do is compute numerical answers to
symbolic problems, you will not do well (because the value you added to
yourself would be close to zero.)

Take a look at this brilliant artwork created from words
on this page. How much do you suppose it cost to have this complex work
created?

When we do graphing-calculator activities in class, you may use your laptop or iPad or Smartphone or calculator to participate. However, using technology in class for non-math activities is prohibited and a severe breach of etiquette.

Section
summaries: Your
job is to

1.1. Learn what it means for a problem to
be indirect and to become comfortable with working indirectly, that is,
writing about operations you don't actually do.

1.2. Learn how order is expressed in written mathematics and on your
personal calculator so well that you can rapidly evaluate complicated
expressions correctly. This requires learning how to insert parentheses
that are not in the usual written mathematics. Practice until you can
get five problems from B2-B16 correct in a row.

1.3. Learn how functional notation is used to express sequences
of operations. Learn to distinguish the function from the notation used
to express it, and how to apply that function to expressions other than
"*x*". (This is also discussed in Section 2.2.)

1.4. Learn how to read definitions and theorems (They express
mathematical methods). Learn how to write mathematical methods in
symbolic notation. (This is a course-long project, begun in Section 1.1
and treated as the focus of Section 1.4. Reading and writing are
essential to word problems, so learning to read and write symbolically
is critical.)

1.5. Learn to read graphs (that is, extract information they
contain). Learn how to graph with your graphing calculator and obtain a
"representative" graph. Learn to select and modify windows, and use the
calculator's capabilities to determine key points on graphs. (This is
continued in Section 2.1.)

1.6. Recall the usual algebraic ways to solve equations. Learn to
rapidly classify equations according to which way to solve them, chosen
from the "four ways to solve an equation." (This is a section on making
good algebraic decisions.)

2.1. Learn how to choose windows that make graphs
"representative"
or have a particular look. Learn how changes in the window will change
the appearance of graphs. (This section continues Section 1.5)

2.2. Learn how notation expresses functional composition. Learn
how given graphs are affected by composition with addition,
subtraction, multiplication, division, and attaching a negative sign.

2.3. Learn that solutions to "f(x) = c"
may not be unique if the
function is not "one-to-one." Learn how to recognize when a function is
not one-to-one and how to deal with the complications that occur when
your calculator has an inverse function but the original function is
not one-to-one.

Precalculus requires you to change!

It is not just more of the same--it is not just more math methods.

You must change the way you think about math symbols to focus on operations and order.

You must change how you learn math to also learning by reading the text outside of class. (This is not high school where your teacher has enough time to cover it all.)

You must change your study habits to devote hours to learning and practicing outside class (even if it is not "fun").

Learning is uncomfortable. In sports you don't get stronger until you lift heavy weights and you get sore with pain. In math you don't get better by doing the easy, painless, work. It takes concentration and, yes, discomfort. Accept that fact and you will do much better.

Thoughts about Learning.

Read each section. Do not skip the harder parts. In fact, when the going gets rough you need to slow down and read it several times until it makes sense. If it remains unclear, ask!

Don't just
skim.

Don't expect
that only high points are important
(Don't read only
the bold parts).

Don't skip
the rest of the paragraph because you
want to move
along to the next high point.

The
original article in The
Atlantic magazine, "Is Google making us stupid," is not short,
but fascinating and worthy of contemplation (However, I don't expect
you to read it):

It has provoked quite
a buzz, so search on
the title will get many hits.Wikipedia has a summary and discussion of responses, pro and con, to the original article.

Learning while multitasking. Recently the news has had quite a bit about research on multitasking. I summarized some of it here, and provide links.

http://www.math.montana.edu/precalculus/Multitasking2.html

"The huge finding is, the more media people use the worse they are at using any media. We were totally shocked."

A summary of new research on multitasking says it has a negative effect on learning. You will be better at what you do if you do one thing at a time. (For example, don't switch attention to texting [at all!] or Facebook while you are studying.) And, you will get as much or more done. Don't kid yourself that multitasking is somehow efficient. It is not.

to resolve it by signing up (with Dr. Esty in 2-238 Wilson Hall) for
our alternative exam time (probably 4:45 the same day for common-hour
exams). However, you must sign up well in advance. Signing up
the last day is not an option.

We use calculators a great deal. Instructors will use the TI-83 or
TI-84, but you may use other models or iPad or SmartPhone apps. Learn
to use technology. If you use a TI calculator, one program you will
need many times is given next.

Activities. Chapter 1

Program your calculator with the Quadratic Formula. Here is a simple four-line program for the TI-83 or 84. Here it is:

Here is how to program it:

Hit PRGM

ENTER

Prompt A, B, C

To find the

Arrow right to I/O (for Input/Output) and down to

For "A", type ALPHA A, (then ALPHA B, ALPHA C, then ENTER)

At this line, you can QUIT (2nd QUIT)

If something goes wrong, don't worry. Just QUIT (= 2nd QUIT in yellow) and resume from where you were by hitting PRGM and, this time, EDIT (instead of NEW).

[Now "quit" and try it out on an example where you know the answer. For example, to run it, hit

PRGMarrow to QUAD and hit ENTER and ENTER again.

Try to
solve x^{2} - 8x + 15 = 0. Did you get 5, 3?
If not, check your keystrokes.] If you want to do a second
example, you need not begin over, just hit ENTER and it will ask you
for the next value of "A".]

Prior to each exam there will be review sessions [dates and times to be announced]

You must come prepared to show you have seriously tried the problems you ask about. Do not kid yourself that asking questions on Monday is good preparation for a Tuesday exam. Most of your preparation should have been done long before Monday!

We have free tutoring all day long in the "Math Learning Center". (However, it is closed the hour before the exam.)

Exam 1, like all Precalculus exams, comes with instructions. It says, "Show clear supporting work on problems with several steps. Algebraic problems that display little or no supporting work will get little or no credit. You do not need to show work on one-step calculator problems. To solve numerical problems guess-and-check is legal unless you are requested to solve them 'algebraically.'”

You should look at old versions of Exam 1. View them on-line here.

Be careful when you study the old exams. Not all old first exams cover the same sections. This semester the first exam covers Sections 1.1 through 2.3. (Some semesters only covered through 2.2.) Each exam says on the top which sections it covers.

You are supposed to know a lot of algebra already. There are several levels of algebra, and most of the algebra you learned in school is at a lower level--a level that will not be emphasized on the exam. The exam tests you on higher-level skills. It tests you on material newly learned in this course.

Be sure you can do the "B" problems. If there is something you don't know, or don't know how to do, be sure to study that. Don't be content with the algebra you knew before you signed up for this course.

You are responsible for reading and writing mathematics. On the exam we will state theorems or definitions that you have not seen before and ask you to read them and use them. This is a skill that cannot be picked up in an hour or two. You learn to read by reading. We strongly recommend you learn to read math by reading your text.

On the exam we may ask you to state methods symbolically (as in Section 1.4).

Be sure to bring your graphing calculator with the Quadratic Formula programmed into it.

There are many problems you will find hard if you have not put a lot of time in playing with your calculator and reading your text. You do not develop reading skills (required on the exam) by watching your instructor. You do not develop calculator skills without practicing a lot.

Have your MSU e-mail forwarded to the e-mail address you actually read:

https://forge.montana.edu/projects/198/wiki/How_Do_I_Forward_My_Student_Email

Go there and fix your e-mail address! Faculty will occasionally send e-mail to you at your default MSU e-mail address. If you don't have it forwarded, you won't get it. If you fix it now, you will avoid four years of problems. Also, give MSU the phone number you actually use. Sometimes faculty need to contact students and they don't have their phone number on file.

The Kahn Academy has Precalculus videos too, but most of what we are do is in their algebra and trig sections. Unfortunately, they have very many videos and many seem to develop the topics slowly and often in a disorganized fashion, so I doubt anyone would want to wade through them all.

In college your instructor does not have enough class time to cover all the material. You are responsible for all the material in the text anyway. You are expected to learn the rest outside of class by reading the text. The homework and exam questions are all closely related to things discussed in the text. Read it! Then, if something is not clear, put in the time and effort to figure it out.

Make sure you have a Quadratic Formula program in your calculator.

"At a certain point we either gonna have to put away childish things and discipline ourself about how much time do I spend being passively entertained. And, how much time do I spend doing stuff that actually isn't that much fun minute by minute, but that builds certain muscles in me as a grown up and a human being?
