NOTE TO THOSE ABSENT: I gave out two Daily Grade sheets to be worked as open book open note, but no outside help and turn in on Monday. I am leaving the extra copies of these in envelopes on my office door. You may come by and pick up one of each so that you will not miss the opportunity to do these problems.
IF YOU KNOW THAT YOU WILL NOT BE IN CLASS ON MONDAY, YOU MAY SLIDE YOUR PAPERS UNDER MY DOOR BEFORE CLASS; AND I WILL STILL COUNT THEM.

NOTE TO THOSE SEEKING A TUTOR: I received an email from ACE today... They are offering tutors this term. You can go to Tutoring Services, 3rd floor TMB and complete an application or you can apply on-line through the JSU homepage.
Fri. May 5
No Class
Mon. May 8 NOTE: Planned assignment has changed for today!
6.1A thru C; 6.2A & C; 6.3 (#1-4; 15-25); 8.3 (#1-10)
Notes #15 now applies to today's assignment; although for 6.3 (Solving by completing the square) we only covered the most routine problems where the coefficient of x^2 (x "squared") is already one and the coefficient of x is even.
In 8.3, we only covered the most basic parabolas, starting with f(x)=x^2 having a vertex at (0,0) and turning up. Then we discussed "vertical translations", such as f(x)=x^2 + 1, which graphs by moving the previous vertex UP 1 to (0,1), and f(x)=x^2 - 3, which graphs by moving the basic vertex from (0,0) DOWN 3 to (0,-3). "Horizontal translations" were also briefly mentioned: f(x)=(x+1)^2 moves the basic vertex (0,0) to the LEFT 1 to (-1,0). This is because the x-intercept, where f(x)=0 was also the vertex, and it is now found where 0 = (x+1)^2, so x = -1. The rest of 6.3A & B and the rest of 8.3 will be covered tomorrow.
MAJOR TEST #1 will be as scheduled (see below). A Highlighted Syllabus is being posted under Course Info, and should be available to look at in class tomorrow.
NOTE: 10:00 PM Mon: I am posting this info and Notes #18 for use in class tomorrow. I will have the highlighted syllabus for the test up later tonight.
UPDATE: 11:30 PM Mon: Highlighted Syllabus is posted for Test.
Tue. May 9 Finish 6.3A & B; finish 8.3 & start 8.4 using WS#11 & #12
I do parabolas differently from the book, so you will definitely need to get these 2 worksheets and probably Notes #18, particularly if you missed class.
BRING WS#10 on Thursday. You will benefit from doing this worksheet BEFORE I lecture on 6.6 on Mon. It will be easier to understand if you have it with you on Thurs.
Wed. May 10 MAJOR TEST #1 (Highlighted Syllabus is posted under Course Info)
We will spend the first 30 to 45 minutes letting you ask questions, then we will go to Room 355 to take the test.
Thu. May 11 Finish 8.3 & 8.4A & B; 6.4; 6.5A-E; WS#9 & #10
PLEASE BRING CALCULATORS, WS#15 & #16 ON MONDAY.
We didn't get to spend as much time as I had planned on parabolas, so try to make progress on them; but we will take some more time on Monday. Use the bottom half of the second page of WS#11 to see the kinds of questions that you will be asked about parabolas on the next test. We have discussed the basic procedure for doing #1 & #2. For #3i, remember that to find a y-intercept, you just set x = 0 and solve for y. For #3ii & iii, to find the zero's of the function means to set y = 0 (or f(x) = 0) and solve for x. If this sounds familiar, that's good because this is the same procedure that is used to find x-intercepts. If the solution(s) that you get are real numbers, then they represent BOTH the x-intercepts and the zero's of the function. However, if the solutions are complex numbers, then they are not real and can NOT be points on a graph, so the conclusion is that there are NO x-intercepts. These complex solutions do, however, represent the zero's of the function. You will notice on WS#11 and WS#12 that the "d" column gives the zero's of the function for each equation, and the "e" column gives the x-intercept(s) for the same equation. Comparing these two columns, you will notice that they are either the same each time (if the first are real numbers), or there are no x-intercepts (if the "d" column has an "i" in it.)
DAILY GRADE #3 was given out. It is due on Monday. I have left copies on my office door (127) if you missed class today.
Fri. May12
No Class
Mon. May 15 Finish 8.4A & B; 6.6; 8.6; WS#15 
Notes #19 for Tuesday.
NOTES #19 & #20 have been uploaded.
NOTE ON WS#15 & ws#16: These 2 worksheets are for practice calculator work. Try these with the idea of NOT doing part of the calculation, writing down and having to re-enter the number later. This method can easily lead to "copy errors" and is prone to "round-off" error. SO, try to use parentheses as needed to enter the whole problem into the calculator. Make sure you know how to use your calculator to do powers, different roots (cube root, fourth root, etc.), find "log of" or "ln of" a number, and proper use of parentheses. Please ask me if you are having trouble with these worksheets.
Sorry I forgot the even answers before. Hopefully, I have remembered the ones that I assigned:
EVEN ANSWERS to 6.2B: #22. {8,2} #24. {4} #26. {20}
EVEN ANSWERS to 6.5C: I do not have a good way to do square root symbols or the "plus or minus" sign, so I will be forced to do a combination of words and symbols for answers:
#34. "plus or minus" the square root of 3; "plus or minus" three on the square root of 2;
#36. "plus or minus" 2; "plus or minus" the square root of 15 "over" 2;
#38. "plus or minus" 3/2; "plus or minus" i on the square root of 5;
#40. "plus or minus" the square root of 6 "over" 3; "plus or minus" 3 on the square root of 2 "over" 2.
EVEN ANSWERS to 6.5E: #56. Larry: 52 mph, Terrell: 54 mph; #58. 20 mph.
Tue. May 16 9.2A & B; 9.3; 10.1; WS#13 & #14.
NOTE on 9.3, WS#13 & WS#14: You will definitely want to get these 2 worksheets to use for 9.3. IGNORE the book's instructions for 9.3. USE the instructions from these 2 worksheets for 9.3. WS#13 will let you make sure that you know how to correctly find the POSSIBLE RATIONAL ROOTS for a polynomial equation. (The book does not give these answers; but I WILL ask a similar question on the test.) WS#14 will save you time and tedious frustration of having to do a lot of trial and error to find the first one or two solutions (and thus factors) that will "unlock" the equation to further factoring or use of the quadratic formula. Again, this is the way that the quesion will be stated on the test, so you will be familiar with the process.
For 10.1, you might want to use Notes #19.
You will want to bring Notes #20 for Wed. I think that this will help you to understand logarithms more quickly and easily.
TWO DAILY GRADES GIVEN: One assignment was done in class, open book for about 20 minutes and turned in. If you missed class and would like to do this one for your own benefit, you may pick up a copy from the envelopes on my office door. (127 AH) I also gave one as a take-home to be turned in tomorrow. These will be in the other envelope on my door. NOTE: If a Daily Grade is not turned in on time, but you still want me to check your work, I will do so.... You just will not have a grade recorded for that assignment.
Wed. May 17 9.4; 10.2; 10.4A thru E; WS#17
Notes #20 were used today for 10.4 and will be used again tomorrow.
WS#17 goes with 10.4A to give more practice with evaluating logarithms without the use of a calculator.
Note on 10.4D & E. We did not really have time in class to completely discuss problems of these types, so don't panic. We will discuss this in more depth on Thursday. Try to get the "definition of log, base b" firmly fixed in your mind from the problems in 10.4 A thru C.
NOTE on TEST #2: Since I was already going to have Test #2 in 2 parts, one without calculator and one with calculator, we decided today to do the second part (WITH calculator) on Wed. This will allow some time for a few questions on Tuesday before the first part of the test. Then for Wed, we can decide whether to have a short review, the 2nd part of the test, and time to start the final review; OR just a long review, and the 2nd part of the test and go home. Either way is fine with me. See dates below. The tentative highlighted schedule has the secions color coded for Part I and Part II.
DAILY GRADE ASSIGNMENT: Do #42 on page 476, and turn in tomorrow for a daily grade.
Thu. May 18 LAST DAY TO DROP PASSING WITH MY SIGNATURE. After 5/18, it is out of my hands... I couldn't drop you even if I wanted to.
Finish 10.4; 10.6A thru D
NOTE: Best laid plans of mice and men.... We didn't get through the last 2 sections 9.5 and 13.1. These will be covered on Monday and will NOT be on Test #2. They WILL be covered on the Final Exam.
Daily Grade Assignment was given out and is due Monday. Copies for those absent today are on my door. If you want it graded and returned by Monday, you can slide it under my door on Friday, and I will get it over the weekend.
Fri. May 19
No Class
Mon. May 22 13.1; 9.5 & Review for Test #2
REMEMBER: We will meet in Room 355 (AH) for the test on Tuesday and Wednesday.
On Tuesday, there will be about 30 minutes at the beginning of class to ask questions before the test. On Wednesday, we can easily take an hour before the test for questions.
REMEMBER TO BRING YOUR CALCULATOR ON WEDNESDAY!
