So today Mr. Max went over some review and told us what kind of questions would be on the exam. Heres the pictures

Hey, Today we're reviewing Statistics and Personal Finance. Mr. Max also handed out the key to the Vectors Quiz today. Tomorrow he is going to give us back our vectors quiz.

Hellloo.. So today we are finishing up with exam review starting with vector examples.

Our first example is from the Janurary 2006 exam, question 11:

Marina and Phillip are pulling a rock with equal force. They are at an angle of 40 degrees to each other.

a) If the resultant vector has a force of 50 newtons, determine the magnitude of the force with which each pulling. Show your work.

(Mr.Max also said that in the past years Euklid has not worked during the exam and said if that happens not to worry because it will not effect our mark)

Displayed here is the solution to A) on Euklid:

The magnitude of the force is 5.3 cm.

b) If the resultant force remains at 50 newtons, at what angle could Marina and Phillip pull in order for Marina to pull with double force of Phillip. Show your work.

Probability Review:

M/C - 1-2 questions

C.R - at most three questions -- most likely 2.

POSSIBLE TYPE QUESTIONS

1) Pathway Problem (PASCALS triangle - type solution)

2) F.C.P (fundamental counting principle). Tree Diagrams/Sample Space/Notation/Factorials/and maybe Perms and Coms

*3)* Independent and Dependent Events - where the "denominator" changes from part to part.

4) Mutually Inclusive/Exclusive Events

Mutually Exclusive(cannot overlap) - P(A or B) = P(A) + P(B)

Mutually Inclusive(can overlap) - P(A or B) = P(A) + P(B) - P(A&B)

Example(s):

-10 people emergency 7 people(shock), 8 people(broken bone), 2 people(cuts)

a)P(shock)

A=7/10

b)P(broken bones)

B=8/10

c)P(cuts/abrasions)

C=2/10

d) Which could be mutually exclusive? And which are definitely not?
Could be Mutually Exclusive: shock and cuts and broken bones and cuts.

Definitely Shock and Broken Bones can not be Mutually Exclusive because 15 together is too many people.

More Math.........

So today in class Mr. Max started to go over our Exam review, he only finished going through Matrix Modelling, and Vectors, before we had to stop because of early dismissal.

As a side note, Mr. Max will be here this Sunday at 1pm for anyone who has questions from any of his math classes and also for anyone who needs time to study.

QUESTION TYPES 4 EXAM

Okay so today Mr. Max handed out a bunch of our marked work, then he went over the different question types for the exam.
This is what they were:

SR - Selected Response(Multiple Choice)

CR - Constructed Response (Show ALL work)

RR - Restricted Response -> just the answer, no need to explain why, but maybe how.

RRE - Restricted Response with Explanation -> the answer along with some means of support.

OR - Open Response -> Probably very many correct answers, and the answers usually conform to some sort of criteria/characteristics that allow for a correct "range" of values.

Also during this class, We went through the DESIGN A FERRIS WHEEL question which is from our Sinusoidal equations unit. I will post the question solution tomorrow because we did not fully finish it today in class.

January 11

To start class Max went over what the "schedule" for our exam will look like, (or what we are supposed to look forward to :s)

Then how to find out the min mark you need to pass the course

Then he gave us this question to try

And finally he gave us these formulas that would probably be good to have on your cheat sheet.

Hello classmates,

Sorry about the late post I apologize Yesterday Coach was teaching us some more about periodic functions we were taking a look at the winnipeg question we were assigned, here are some pictures of the work he did to show us the answer:

We also took a look at another question, the frog on a lily pad going around on a paddle wheel, hard to belive but we dont care we are just solving it right

I hope that these pictures will help you when you need to look at examples on periodic functions learning about sinreg. Good luck on the exam everyone!

Jan 10th work

There was 3 questions that we were able to choose from the day before and these diagrams show the answers for all three. For tonight's homework you have to finish the other to questions from yesterday if you need help make sure of an answer you can peek at the diagrams. Keep studying hard for the exam and you will all do well. Good Luck!

Blogging Self-Assessment

As we near the end of this course, I'm looking for your assistance in generating a 'score' for your contributions via the blog for the semester....Specifically, and with respect to the photocopied handout entitled, "Blog Scribing in Room 204", use these questions to help you formulate in your own mind an idea of what mark you deserve.

I'll hand out a rubric in class to help you finalize an actual score, with weighting....

1. Did you blog when you were supposed to? (within 24 hours?), (and every time you were supposed to?)

2. Do your posts contain relevant screen shots from my Sympodium, incorporated in a meaningful way?

3. Have you ever commented meaningfully to another student's post? Were you gracious, decent, sincere, and timely?

4. Did you just do the bare minimum or did you actually take some time to contribute something worthwhile and meaningful to your classmates?

5. How is your spelling / grammar on the blog? Would your ELA teacher approve or disapprove of your language presentation?

6. Do you think I might have any constructive criticisms of your efforts? If so, consider these accordingly...

7. Did you ever contribute a meaningful image, link, thought, idea that was beyond the scope of classroom discussion. Did you ever exceed the expectation of your responsibilities to your classmates?

The only way that I believe that you should consider awarding yourself full marks in this category of your assessment for this course is if you can honestly and sincerely reflect upon these questions and award all the marks available as a result. Some of you deserve these marks, but some of you certainly do not. The rubric I hand out in class will help you determine an actual score....

Comments here might be appropriate if you have any reflections to share about this process.

applications of periodic functions

Today we started "Applications of Periodic Functions". We graphed y=sin(x) then started to learn transformations. The first one is the "A" value, it is the amplitude of the function, or the distance from the highest point to lowest point divided by 2.

The second transformation is the B value which is associated with the period of the function. The formula is period=2pie/B.

The period is the amount of horizontal space required for the function to repeat itself once.

Then we did phase shift which is simply the horizontal shift of the entire graph. Phase shift =-c/b

Finally the D value, vertical shift. If D is positive you move the whole graph up D amount and if D is negative you move the whole graph down D amount

y=Asin(Bx+C)+D

December 20th

December 20th was our last day of math class before the Christmas break. During this class, we played the "Chaos Game" and we watched a video about Arthur Benjamin, the "mathemigician".
Hope everybody had a good Christmas and don't forget to study for the exam which starts on the 22nd!
