Notes for the Final Exam

A-Block Review 6/11 7:45 - 9:10
B-Block Review 6/12 7:45 - 9:10

You are welcome to come to both review sessions if you have a study.  I will write you a pass.

The final is on Wednesday, June 13th from 12:00 to 1:30.  You can stay until 2:00.  You should get there a little before noon so you can get settled, return your book, etc.

For the final you need to bring:

  •    pencil (please do not take your final in pen)
  •    eraser (no sharing of anything!)
  •    calculator (you may want to bring extra batteries just in case - no sharing!)
  •    book


A-Block in room 613 (I will be with you 12:30 to 1:00)
B-Block in room 614 (I will be with you 1:00 to 1:30)

Where I will be the other times:
   room 615  12:00 to 12:30
   room 616  1:30 to 2:00

You can find me and ask questions at any time but it would be better if you wait until I am in your room or just next door.

Counting and Probability

This unit starts with ways of counting possibilities.  It takes a few days to learn all of the counting techniques.  We then use that to determine the probablility of different outcomes.

Conic Sections (or how to slice a cone)

Chapter 9 covers the study of conic sections, relations that are usually not functions.  This means more work to graph the relations with your calculator and more solutions when we get to word problems.  Be ready!  Conic sections are circles, ellipses, hyperbolas and parabolas.  Circles are a special case of ellipses so they will be done altogether.  Every case has an algebraic and a geometric definition.  We will study both.  (There are more ways of expressing conic sections - polar and parametric definitions - but we won't be getting to those this year.) We will spend two days on hyperbolas, a day focusing on the algebraic and a day focusing on the geometric definitions.  We won't get all of the vocabulary the first day so some of the homework needs to be revisited the second night. The geometric definition of parabolas will show us some important features of this quadratic relation that were hidden before.  Given that we spent a great deal of time with the algebraic definition of parabolas in a previous unit, the single night of parabola homework focuses on the similarities with the other conic sections.

Exponential and Log Functions

Exponential and Log functions are inverses of each other.  That is the most important thing to remember about them together.  We have been studying functions where x is the base and the exponent can be positive, negative or fractional.  Now we will study functions where the base is a number and the exponent is the variable.

Note:  I am not following the order or the emphasis of the book so we will have handouts everyday but this material is covered in Chapter 6.

Rational Functions

The next unit is on Rational Functions (functions that can be written as fractions with polynomial numerators and denominators). The first day was an introductory activity. The second day was a graphing activity. I will not give you homework until we have a more in-depth discussion graphing activity. The unit will really start in earnest after vacation.

Typo alerts

There are two typos that I have found that make a difference. The first one is in Example 2 of the Extra Practice Factoring and Dividing worksheet. That one I put the correction on the board (the third line of the example should have -6 not +6). The new correction is on the Finite Differences/Technique Review worksheet. Problem 5 has a table of numbers. The point (3, 15) should be (3, -15). Left unchanged you will have a great deal of difficulty practicing the finite differences technique.

Midterm Histogram

The histogram of midterm results is here. We set the average for the scale to 80%. This means half the students did better than 80%. It is normal that half the students are below the average but it is not good if they spread way out below the average. Theoretically, if half the students are between 80-100% then the other half should be between 60-80%. That is not the case with this test. The tail falls off at 42%. More than three quarters of the students got a score above 70% on the test but those that struggled really struggled a lot. My students that did poorly need to see me so we can rethink what they need to do to be successful. Do they have good techniques for studying (which is different than being diligent)? Are they trying to memorize procedures without really understanding them? A lack of understanding is exposed when questions are asked slightly differently than before and the student is unable to adjust to the change and answer the question. I want my students to be happy and successful in my class but the curriculum and the pace cannot change so let's work together for best results.

Finishing up Quadratices (and the term)

We still have to look at complex numbers, an integral part of our study of quadratics. We will finish up Chapter 5 and have a mid-year exam before the end of term 2. (Dates given are for A-Block, B-Block is one day later for the end of the week.) Remember that I am trying not to overwhelm you with homework but if you need extra practice, there are plenty more problems in our textbook.

Both sections will have their second quadratic quiz on 1/12. They will also both receive the mid-year review packet that day. Both sections will have two days in class before the exam to ask questions and work on the packet. Both sections will have the Mid-Year exam on 1/19. Quadratic Inequalities will be on very different dates for the two sections and will not be assessed on the second Quadratics Quiz.

Remember that the makeup for the first Quadratics Quiz must be completed by 1/13. Test corrections for the Matrix test are due by 1/20. Retakes for the second Quadratics Quiz are due by Tuesday, 1/24.

Quadratics

For the quadratic functions we will be using books with a more investigative focus.  After each investigation we will summarize the results and I will collect the "Check Your Understanding" to check your understanding.

Day 1  Investigation 2/all pp.332-334
              HW pp.346-357/A 7-10; C 17; R 28,29; Rv 43-45, 4

               HW pp.348-358/A 13-15; R 31, 33; E 39, 40; Rv 51, 52

On the 6th day we will add a few things that are not in the book (vertex form and quad regression).
On the 7th day we will review techniques for factoring and solving.
On the 8th day, there will be a quiz.  This will probably be the last day before vacation. The quiz should only take half the block, then we can play a game.

Since I am not issuing textbooks for this unit, I have uploaded the pdf of the unit into the conference.  You don't have to go online, you can just use that. Or download it from here. (Note: If there are contents links on the side, you may not be able to click on them - use actual page numbers at the top).

The reflection

Our analysis of 3D systems using rref led to several different results - more than we saw when using rref on 2D systems.  Of course, in 3D, more things can happen - as you saw from your brainstorming with your three "planes".  I would like you to write a reflection of the similarities and differences between systems of equations and their rref matrices in 2D and 3D.  This should come after your final analysis of the systems on the worksheet.  With 2D we knew which systems were consistent, inconsistent, and dependent from their rref matrices and what the system looked like when the lines were drawn.  Were you able to do the same with your 3D systems?

An introduction to the mathematics of 3D

We will be moving into chapter 4 which studies matrices - a technique that allows us to handle huge amounts of data. 3D makes a great bridge topic between systems of equations and matrices. Remember, this is only an introduction. You do not have to be an expert! That comes in two years. ;-)

Day 1: Representing 3D with points, equations of planes, graphs.
Day 2: Solving systems of equations in 3D - there are many possible outcomes. (Answer Key)

The homework both days is to finish the handouts.

Transformations

We have been talking about what functions are and how we can combine them. Transformations are about manipulating functions - moving them around, changing their size, flipping them over. We are studying the topic in general but every time we study a particular kind of function in the future, we will again discuss how the transformations affect that function. This is section 2.7 in the text.

Because of the Friday Professional Developement Day, A-Block will have one more day on the topic (a moving-around activity!!). Thus, I have used a table.
