Announcement: Did I tell you -- At the MathXL site there are online problems to practice from most of the sections we have covered in class. Log on as "Rowdy2010" and use the password "Rowdy2010Z". Click on "MA134 -- Rowdy's Workout -- 2009-2010" and then click on "See all assignments" and then choose a section and try some problems.
____________________________________________________________________
Announcement: A considerably-improved a Review for Test 1 is now available -- you might start with the skeleton and fill in section names, ideas, formulas ... and work problems.
Wednesday, September 23 -- Day 9 (in Cape) / Thursday, September 24 -- Day 10 (in Sikeston): We worked with the 10 Standard Graphs -- formula, sketch, domain, range, symmetry (and even/odd), whether or not a function. One of the test questions will be "Write the 10 Standard Graphs -- formulas, sketches ..." (and perhaps more.) We discussed symmetry -- Section 1.7A. We started talking about transformations -- Section 1.7B.
HW September 23/24:
-- 1.7A.
-- Study the 10 Standard Graphs (sketch, domain, range, symmetry, whether a function or just a relation);
-- 1.5D (again);

-- Work on a Study Guide for Test 1: Make a list of topics and corresponding main ideas and formulas, and corresponding examples and problems.
================================================================
Week 6.
Monday, September 28 / Tuesday, September 29: We put problems on the board, and went over 1.5D, and completed our discussion of 1.7B: Transformations on Standard Functions. We took some questions and spent some time reviewing for the test.
Wednesday, September 30 / Thursday, October 1: Test 1
HW Sept 30 / Oct 1: 1.7B; Calculator Graphing 7, 14, 15, 16. May put these on the board, and/or may turn them in.
=============================================================
Week 7.
Monday/Tuesday October 5/6: Put problems on the board from 1.7B. A few comments on performance on the test ("Some did very well.... some did very poorly ... it was clear that some people did not do much homework, and did not do much studying. Not much homework, not much studying leads to failure. Make changes if necessary.") Main topic: Graphing quadratics and word problems with quadratics.
HW Oct 5/6: (You may want to go over 1.7B -- we may have a quiz next time.) 2.4A, [B], W. The problem set mentions Rowdy's Workout. Ignore this.
If necessary, learn how to do problems with circles -- Book Examples 10, 11 page 67, and Example 1 page 534 -- and homework sets 3.1C and 6.2A.
If you don't know them, learn the 10 Standard Graphs: y = x2, x = y2, y = sqrt(x), y = x3, y = cube root(x), x2 + y2 = R2 , y = 1/x, y = 1/x2, y = |x|, y = 2x.
__________________________________________________________________________________
Wednesday/Thursday October 7/8: Comment on the board before class (in Cape):
Symmetry is a property of graphs , and the possibilities (in this class so far) are . . . wrt x-axis (x = y2 ), wrt y-axis ( y = |x| ), wrt the origin (y = x3), or no symmetry ( y = 2x ).
Even/odd is a property of functions, and the possibilities are . . . even (y = x2), odd (y = x3), neither ( y = sqrt(x) ), or not a function ( x2 + y2 = R2).
Put problems on the board from 2.4. Quiz over 1.7B. Main topic: Inverse Functions (4.1).
HW Oct 7/8: A. "10 Standard Graphs": know the graphs, and know symmetry and even/odd.
B. 4.1A, B, C, + 4.1X (new): 83, 84. Scratch out 4.1D.
C. Problems from 2.4 may be turned in next time.
D. R.2, R.6 -- read the book on your own, and work problems to review these ideas. Need them for the rest of Chapter 4, probably the most challenging chapter in the book. May also practice these at Rowdy's Workout. We may have a quiz on this next time.
=================================================================================================
Week 8.
Monday/Tuesday October 12/13 :
Put problems on the board from 4.1. Discussed them, along with two
problems from the test: Compute the difference quotient for f(x) = 3x-2
and Complete the square to solve 3x2 + 2x + 4 = 0. Most
of the time we worked through 4.2 "Properties and Graphing for
Exponential Functions." Last few minutes (
HW Oct 12/13: ("BX" means "Book's Example". Optional items are in [brackets.] ) In Section 4.2, look at examples: [BX1, BX2]; BX3 (very good, but use transformation ideas, not the tables); [BX4], BX5, BX6, BX7 (again, use transformation ideas, not the tables). Exercises -- 4.2A: 14, 15, 17, 21, 25, 27, 29, 30, 31, 36, 36, 39 (book's answer is wrong -- what should it be?). 4.2W: 55, 57, 63.
Circles: If you didn't learn the material on circles before, you need to know it now: BX 10, 11 page 67; and BX 1, page 534; homework assigned on circles was 1.1C and 6.2A. If you understand the circle problems, you can do the ellipse problems -- see below.
______________________________________________________________________
Wednesday October 14 (
HW Oct 14: Not on assignment sheet: Read pages 631-633, especially Examples 1 and 2. Do p. 637: 1, 3, 5, 7, [9], 11, 13, 19.

____________________________________________________________________
Wednesday, November 4 / Thursday, November 5-- Day 21: Presented new material almost the whole time, on 4.6 Exponential Growth and Decay, and then on 3.1 Introduction to Graphing Polynomials. Did not take time for questions, but will start next time with being open to lots of questions.
HW November 4/5: (almost verbatim from the "Second List"): In book, explanations and Examples 1 and 5 are good. Work MXL 4.6 and Paper 4.6: 1, 2, 4, 5, 6, 15. AND. . .
MXL 3.1A, 3.1W. Suggest you read Section 3.1 in the book before attempting these. Then, optionally, for paper practice, you may want to do some of the book’s problems -- suggest you pick some from the odds in 11-17; 19-22; 27-45; 49, 51.
AND . . .
go to the Math Department MA134 web page, and print off a copy of the Study Guide for the Final -- the "Common Final Problem Study Set". There are other items there that you might find interesting. Next time, I will call the roll and if you show me the Study Guide, you get an extra 5 points. If you don't have a copy, you may lose 10 points.
There seems to be some confusion about when MathXL assignments are due. Here are the rules:
1. Any MathXL assignment includes the deadline date and time on the MathXL homepage, where the assignment is listed.
2. You may NOT assume that a MathXL problem set assigned one period is open until the next period. This may be true for most paper assignments, will not be true for MathXL, in general. Check the MathXL page where the assignment is written, and don't wait until the night before the next class period.
3. In general, MathXL problems assigned on Wednesday or Thursday will be due Sunday night at midnight.
For Math XL 4.4, the deadline is extended to Wednesday, 11:59pm.
_________________________________
1. (a) All of the old MathXL has been re-opened, until Sunday midnight, after which it’s closed forever. (b) The newest MathXL is open until Monday noon – start sooner than Monday morning.
2. On MathXL 4.5B, the last two questions mention the INTERSECT feature on a calculator. On the TI83, this is a menu item after pressing 2nd and CALC .
==================================================
