Friday 2/1

Enjoy your weekend, no hw for either class.


pre calc -   We did many applications of sinusoids today.  In the book we did #86, 75-78 in section 4.5.  the final part of class was group work on writing a sinusoid about ocean tides.




alg I   -   After warm up 4 we turned in our work and compared linear vs exponential functions. 

thursday 1/30

There are quizzes coming up for both classes so check the announcement board to see when.


pre calc -   In section 4.5, we did #14, 16,  and 88 together.   In groups, you worked on #39, 40, 43, 49, 51, 53, 71, 72, 83.   Finish for hw if you did not finish in class.

tuesday and wednesday

Since we have special schedules, you only saw me on one of these days.



pre calc-   Tests back, we'll finish 4.5 notes and do a little practice; last part of class is the performance task for right triangle trigonometry.





alg I -   After reviewing the test, we took notes on rules of exponents and then did a budget for 3 different occupations.  Hw is the 6 exponential problems on the board.

Monday 1/28

pre calc -   We were able to review the unit circle and Soh CAh Toa.  Period 4 was able to start the 4.5 notes on sinusoidal graphs.  No hw.

alg I =  We finished the Youre Toast Dude activity and did a warm up 4.  You also need to study for your test.

Tuesday 1/22

pre calc -  We practiced our right triangle trigonometry and finished with an identity.  Test is Friday, work on the study guide and ask questions!



alg I -   After reviewing functions, domain and range, we did warm up 3.  Test is Friday, so work on the study guide this week and ask us questions.   

alg I function test review guide

The next test is 9-10 problems testing our knowledge of functions.  It is on Friday 1/25.

The following would be good to do if you would like to prepare.  Bring in your questions on the days before the test.

1. Draw 3 graphs that are functions.  Draw 3 graphs that are not.
2. Name the 5 parent functions.  Which have restricted domains?  Which has restricted ranges?
3. If p(x) = -11x +5, then evaluate p(-4).
4. Graph y = (x+1)2 - 6.  What is the range?
5. Graph y < 2x - 7.
6. Solve the system:  y = 5x - 2 and 2x - y = 11.
7. Write the equation for the function that has points (-1, -3), (0, 1), (1, 5) and (2, 9).
8. Write the equation for the function that has points (0, 2), (1, 1), (2, 2) and (3, 3).
9. Write the equation for the function that has the points (-1, 3), (0, 4), (1, 3), (2, 0) and (3, -5).
10. In the arithmetic sequence (-4, -1, 2, 5, 8…), what is the 42nd term?

Be prepared to do a work problem like the one of page 432 #11 and p. 492 #3.

Friday 1/18

pre calc-   Took a few more notes on identities and did a practice problem on a non-unit circle.   We then voted to either do more identities or worked on p. 289
\

tuesday 1/15

I'm back!



pre calc - After reviewing Monday's work, we finished notes and did unit circle practice.  Hw was the l8 problems I projected on the board.


alg I -  We also reviewed Monday's work and went to the library.  On the computers we did 2 Desmos activities.

monday 1/14

I was at a conference so this was a sub day but there was still important work so I hope you did it!

alg I -  in the Holt book, arithmetic sequences #9-19 odds, 22, 25, 26, 30, 33

pre calc review guide - basic trig

this is a bit early but some people like to get ready in advance.

The first trig test will be 13 questions, though there are multiple parts to some questions.  It is 80% identical to the pre test.  How about those apples??

1 converting degrees and radian
1 naming coterminal angles
1 naming reference angles
1 where you're given 1 trig function ratio and are asked to find another
3 using right triangle trig or pythag or triangle sum to find missing info
4 finding the exact value of trig value at an angle (ex.  sine 60 dgs = )
1 solving a basic trig equation ( sin x = 1/2)
1 trig application involving angle of depression/ elevation (think planes landing)
2 involving the Pythagorean Identities
2  proving a mathematical truth using trig identities (prove: (tan x) (cos x) =  sin x
1 trig application on using a 2 variable equation (think a bouncy spring)

Here are some problems in the book

p. 261 #25, 26, 51, 53
p. 270 # 9-15 odds, 23, 27, 33, 74, 75
p. 280 #7, 59-65 odds, 67, 69, 78
p. 289 #15, 23, 24, 27, 47-49, 67, 68

Friday 1/11
