Review and Final

We will review for four days before the special end-of-year schedule.  Make sure you look over the list of Proofs and Theorems you need to know.  The Final Exam Archive of the math department has a bunch of old finals (with answers!) for additional practice.  (Note: topics change a bit from year to year so don't freak out if there is a question on something we didn't cover.)  Also, all test corrections and grade mistakes must be taken care of by Thursday, June 13th.

6/07  Review Day 1 (Basic Functions, Polynomials and Limits) [answer key]
6/10  Review Day 2 (Trigonometry)  [answer key]
6/11  Review Day 3 (Vector and Parametric Equations)  [answer key]

         Remember to bring pencils, eraser, calculator (and maybe extra batteries?), a stomach full of
         healthy breakfast and a brain refreshed by a good night's sleep.  And your books.

Matrices

The study of matrices involves the most recent applications of mathematics that we study. While understanding the techniques required to manually manipulate the data, we will spend a lot of time using the calculator and the computer.  We will be moving through matrices quickly with a lot of applications.  It is chapter 7 in the Demana book and chapter 14 in the Brown book.

Here is the list of Skill Objectives.

4/26   Algebra 2 Review day
          HW B p.521-522/9,11-13,16;  p.526-528/5-11 odd, 12, 15, 16, 18
                  D p.540-542/33-39 odd, 43, 45, 48, 52

4/29   Matrix Multiplication, Augmented Matrices, etc.
          HW Extra Problems on Matrix Multiplication (link to online Row Operations site)
4/30   Applications of matrices to linear systems
          HW handout includes 6 problems and these Demana problems:
                  p.554/67-70, 73, 74, 76, 78, 79, and p.563/13, 15, 21
5/01   Transformations Day 1 HW p.1-4 of handout

Vectors


Here is the syllabus for the topics. In Demana it is the beginning of Chapter 6.  In Brown it is Chapter 12.  The skills you should know for manipulating and using vectors are listed here.  Make sure you know how to do all of them before the test!

4/01   Intro to Vectors
             Demana p.464-465/3-27 by 3's and 29-39 odd and Brown p.423,425/5-7, 17-20
4/02   Angles between vectors, The Dot Product
             Brown p.444-445/1-19 odd, 23, 27-29
4/03   Vector Proofs (D: 6.1 and B: 12.1, 12.2)
             finish worksheet plus Brown p.425-426/21-23 and p.429-431/11,12,15,18,27-29,33,34
4/05   Equations of Lines, Vectors in 3D
             finish worksheet plus B p.436-437/17,18,23 and D p.466/63,64
             If you still feel that you need extra practice to feel comfortable with the material,
             section 12.5 in the Brown book is the place to go (clear explanations, good
             diagrams, comprehensive problems).

4/08   More 3D: Equations of Planes, vectors perpendicular to planes (B: 12.5)
             Worksheet problems 1-10 plus B p.452/42-45 and p.455/15,21,28-31,33,34
             We talked about equations of planes & vectors perpendicular to the planes. Read the
             corresponding explanations in the book. They are very clear, have lots of examples and
             better pictures than anything I can draw. (This reading should be considered
             part of the homework!)
4/09   Spheres, vectors & planes, Angles between planes (B: 12.5, 12.6)
             B p.450-451/11,13,17,27,31-36,41,42 and p.456-458/21,25,27,34,35,37-39
4/10   The Cross Product
             Vector Cross Product worksheet
4/12   Projections, Distance from a point to a plane
             Work on worksheet and do "Points, Lines and Planes in 3D" problems 11-14

4/13-4/21   April Vacation

4/22   Review Day 1 (download a practice test, download solutions)
  • We went through finding the distance from a point to a line in 2D and a point to a plane in 3D. The question arose about finding the distance from a point to a line in 3D. Look again at the homework problems in the Brown book: p.457-458/34-39.
  • For projection practice, do Demana p.473/25-28 and 58a.
  • If you did not do so, finish the 3D points, lines and planes worksheet (problems 11-14).
  • Other than that, go back and make sure you have done and understood all of the previous homework in light of the objective skills of the unit.

Parametric Addendum

Given that it was tough giving Parametric equations enough time in class, I am changing the first assignment on parametrics to section 12.3 of the Brown book.  Do the following problems on pages 437-439/23-29, 39, 40.  This is our new Day 3.

Polar Coordinates

This is a quick but interesting unit on another way of describing the location of points in space.  It is a somewhat surprising application of trig that can also be used to work with complex numbers.  The schedule is plagued by holidays and MCAS but we will work around it as best we can. Polar coordinates are covered in the Demana book in sections 6.4-6.6 and in the Brown book in Chapter 11.  I am using Day1 notation rather than dates because the E-Block and G-Block sections will be off (due to the half day - but not if there is a snow day on the 7th!).

Sum and Difference Links


There are several resources to view proofs of the angle addition and angle subtraction identities.  Look them over and make sure you understand them.  You will be required to prove some of the basic identities on your test and the proofs of these identities require diagrams which may not occur to you during a test situation if you haven’t thought about them before.

Geometric Trig

Post-test homework was to do the area and identity worksheet. We continue with the more geometric applications of trigonometry. For this unit we will use primarily the Brown book.

1/28  9.2  Area Formula and applications
                HW p.342-344/1-19 odd, 20-22, 35, 36
                (p.344/34 is a bonus problem - turn it in for extra credit)

                HW p.358/38, 39, 40, 42
2/06  Review and Extension Problems (Practice Test/Answer Key)
2/08  Test of Geometric Trig

The Geometric Trig test will have questions that require a full understanding of the trig area formula, the Law of Sines, and the Law of Cosines. There will be one problem (chosen by me) from the "C" problems on page 358 (not 41 or 43). I have not assigned every problem in the unit but notice that after you finish these problems you should be able to find the area, the sides, the angles, the length of the median/angle bisector/altitude, and the radii of the inscribed and circumscribed circles for any triangle - among other things.

The beginning of Trig...


Trigonometry is our longest unit spanning more than two months and three tests. We start in the Demana book but will move into our second book, the Brown book, as we progress.  We begin with Right Triangle Trig, mostly review from last year.

We start with an explanation which is both review and a new way of looking at exponential functions.
Some of the 11/27 homework problems involve regression. Here is a document that will remind you how to do them on the calculator. The example uses a quadratic but I have faith in your ability to extend the information to the exponential and logistic regressions.

Polynomials

Chapter 2 begins with Polynomials. The beginning of the polynomial chapter is mostly review - and then it gets complex (literally!).  The chapter includes how complex numbers relate to polynomial functions.  We will be spending a couple of weeks on polynomials and complex numbers.  Quick, skill-based check-in quizzes could happen at any time after the first three days of basic instruction so stay on top of your homework.

The homework problems on complex zeros are from the old edition of the book which used to take two sections to cover the material.  I liked some of the problems that were deleted in the new edition so you will be given copies of the pages.
