Open Blog... Thursday, Oct.30 2008

Today is open block, so i decided that i would do my part and blog.



We started with mental math. I'm very sorry for stating the answer for number five aloud. It was a mistake.
We corrected the homwork questions that were to be done for today.
Questions 4,6 and 9 on exercise 2: counting principles.


Mr. Max then showed the class a awsome game called Plinko, it was really helpful, it relates to " Pascals Triangle".





GROUP PROJECT: (Plinko)


Compare 2 chip positions using a sketch like this diagram to help you decide where to put your chip.













Good Luck, and have fun!
Its due when ever you finish...

October 29th- "The Tragedy of the Commons"

No Mental Math today because we were running behind on schedule due to Mr.Maksymchuk's tardiness. Because nobody scribed for yeserday, the lesson learned is that you as an individual should take initiative to do something for the greater good. Including being the scribe on a day that it is not your turn to be the scribe. To help us understand this we are to compose an essay with a thesis of the following:

"Relate the events of October 28th 2008 in Block 4 Applied Math to the contents of the famous article "The Tragedy of the Commons" by Garrett Hardin. Use specific references to individual responsibility within the frameworkof the greater good."

The essay is due for Monday, November 3rd. The essay is to be 250-500 words in length. Be sure to cite your contents appropriately in your bibliography.

A link to the article is the folowing:

We went over the question assigned for homework yesterday. The answer to the question was 12/35. We also did notes and learned about the fundamental counting principles. We used an excellent example involving food, especially creme brulee!

The home work for tommorrow is page D5 Exercise #2 Questions 4,6,9 and 5 if you think you can.

The images and video will be folllowed after this post.

Today we started with Mental Math and then went onto correcting the fish tank problem.
Also we went through the marking guide for it.

For the answers and marking guide go to: (page 55)

I'm not going to lie....

You guys continue to impress and amaze....I hope you had a productive afternoon, and I'll see you tomorrow. I especially liked the problem that Alissa posted. It's one of my all-time favourites. Does anyone have a solution?





You know who.





You really think he looks like me? ;)

October 23

Today, we had a sub, Mr. Maxs was gone


Today is a work period for the auquarium question.

Good luck, and have fun!

Here is the question.....

Tuesday, October 21st Blog

This is actually a blog for yesterday, Tuesday the 21st of October. To start off the day we did some mental math. yay! Mr. Maks let us continue doing our math question which was considered as a quiz. We were given yesterdays class to finish the question which had to be handed in by the end of class. I thought it was hard, but that is just me speaking. I hope you all did well on it. :)

October 22nd, 2008

La La La..We started with mental math today..of course!

When is the magnitude of two added vectors exactly double the magnitude of each of them? (Assume their magnitudes are the same)...WHAT THE HECK!! haha, this question troubled me..and it seemed like it troubled a few of you. Mr.Max's answer was---> This only happens when they are going the same direction. Not to hard once he explains it, what a LOL moment.



Anywho moving on from the mental math portion of the day, we checked out the answers for the driveway question. It seemed that quite a few people were off a bit, but alot of people had the right idea.



ANSWERS(all answers are rounded for buying purposes)

Method 1

*Cost of Excavation=$5,280.00

*Cost of Gravel=$792.00

*Cost of concrete=$2,860.00

------------------------------------------

Total Cost = $8,932.00



Method 2

*Cost of Excavation=$5,940.00

*Cost of Sand=$80.00

*Cost of Limestone=$990.00

*Cost of Paving Stones=$4,371.75

------------------------------------------------

Total Cost=$11,381.75



This question had alot of figuring out to do, and there were quite a few interesting moments(cough cough nicole cough cough) =), but we all pulled through.

**Interuption- Doppelganger: a ghostly double of a living person that haunts its living counterpart.



We now have been assigned a previous exam question that is due for Friday. It is on a fish tank...Mr.Max helped to create it.

Good Luck everyone, and have a stupendous Wednesday night..i kno i will!:D

October 20th, 2008

First off, I'd like to say congradulations to the Girls Soccer team, for getting a bronze medal at their provincials on the weekend

Anyway, today we started the day off with Mental Math, than there was a homework check on the "Baseball Diamond" question. The spread sheet that Mr.Maks used to answer this question, may be located on the Coursework Drive in our folder.

We were given a quiz to be handed in for tomorrow: Page 6, of 6

HAVE A NICE DAY!

Friday, Oct 17/08

Today's class is a work period, and Mr.Buckner is our sub again today, as Mr.Maksymchuck wasn't here again today. The assignment is the same; the baseball diamond question on page 5.
As a reminder, the question should be done by the end of this class, or at least be done for Monday's class.

Thursday October 16-Work Period

So Maks was away today and we had Mr. Buckner as a sub. It was basically a work period to that single awesome question that everyone so obviously loves. Spreadsheet work and "partners, rows, then sides" were encouraged. The question is to be completed by the end of Friday's class.
Note:
-The G.S.T is to be changed to 5% from 7%
-(conversions) 1 cubic yard = 3 cubic feet or 36 cubic inches

October 16

Today in class Mr.Maksymchuk educated us on his new fun ability to record his lessons and then upload them onto the blog, but unfortunately when we went to test this new up to date technology the voice that came out was somewhat nasel.. and difficult to hear. So for the benefit of the students, and their learning capabilities, a poll was taken, "if there was no conflicting force in between the mic and Mr. Maksymchuk's voice, would it be easier to hear, and therefore learn?"

54% - Yes, I believe the lessons would be easier to learn.

46% - No, I can hear just fine.

Following this we were appointed the task of working on a ballpark question which is to be attempted first with a partner, then in your row, and lastly by side of room until one answer is giving from both the north and south side to be presented in class on Monday. Its a tricky one, good luck

Fridays blog

Hey, we had a Math test on vectors on Friday. It went by quick but I hope you all did well.

Good Luck!!

1 Day to Vectors Test

Once again we started the day out with Mental Math and a very hard question to do with shingles....... Anyways, Maks then proceeded to show us how to print from Euklid.

Step:

1. Make your vector

2. Press the "PrtScr" (next to the F12 button) which will basically copy your screen

3. Open up Microsoft Word

4. "Paste" your vector into Word

5. Underneath the picture of the vector put the question number and your name

6. Go to "File" then "Print" (the name of the printer is //2SVRSSRS204Lex640) [or something close to that]

Quoting from Maks.......

" DO NOT TRY TO PRINT FROM EUKLID!!!! It makes bad things happen"

Also Maks has offered to stay after school today to help those who need it before the test. He will be staying until 4:45 pm.

For the test Maks is allowing us to use two of the templates that are saved on the coursework drive; a triangle template and a parallelogram template. They can be found under: "Coursework", "Math", "0809 1st semester Applied 12", "Vectors Test". You must open them from Euklid by going "File", "Load".

Reminder: The Vectors Test is tomorrow, Friday October 10th. You are allowed to bring a study sheet but it has to be made by YOU for YOU on a 8.5 x 11 paper. A 1/2 mark will be taken off on the test for every missing vector head!!!

Here are some of the examples that Maks did today:

Vectors

Today in math we started off with mental math, and then Mr Max did examples of the parallelogram method and the triangle method using questions from old provincial exams.

Here are the questions we did:

The diagram above is the triangle method.

The first step to using the triangle method is:

1. Draw an "ugly sketch"

2. Find the magnitude and direction of the first line and then draw it on the orgin. In this case it is, the magnitude is 15 cm and the direction is 40 degrees N of W.

3. You then draw parellel lines from the end of the vector to create another orgin.

4. Next you find the magnitude and direction of the other line. The magnitude is 10 cm and the direction is N.

5. After you have the second vector, you can then find the resultant vector, in this case it is 22.713 cm and 30 degrees W of N.

This is an example of the parallelogram method.

The steps are:

1. Make your ugly sketch.

2. Draw the vectors tail to tail starting at the orgin.

3. You don't know the magnitude of the vectors so draw a ray just using the direction.

4. You do know the resultant vector so draw that .

5. You then draw parallel rays to make an intersection point.

6. You will then know the magnitude of then vectors.

I hope these steps help. Remember test on Friday good luck studying!

The PARALLELOGRAM Method

So in case anyone was wondering what a parallelogram is, it is a shape that includes four angles. the angles horizontal to each other, are considered supplementary angles. The sum of the two equal 180 degrees, as goes for angles A and B or D and C. lines in the shape are parallel as in AB and DC or DA and CB. now that we got that covered we can learn how to use this method. You'll know to use this method when a single angle is given saying that a certain vectors things angle to another vector. A big give away is that the question will have exactly two vectors. anyways the first step is to draw V1 from the origin(tail at the origin). next THE SAME is done with V2(make sure the angle is between the vectors). After create two lines congruent, parallel all that good stuff to the original vectors(hopefully doing this will get you your parallelogram). The fourth and final step is to find our resultant vector. It is made by making a line segment starting form the origin to where the two new lines meet. Measure its magnitude and direction(get your direction from the origin).Remember the vectors will act at the same time if it is a parallelogram question.

A Great Way to Start!

Monday, October 6, 2008

Today is Monday, October 6, 2008. Yay.. a Monday!
We had no mental math. Now that's a great way to start off a new week.

Today Mr. Maksymchuk gave us a work period. We need to finish Exercise 3, Questions 1,2,3,5,7 & 9 for tomorrow, October the 7th.

Just a little reminder to the scriber for tomorrow and the lucky person is Staniland.

Friday October 3

In class we did mental math, Maks gave us our homework assignment, and then showed us another example on how to calculate a resultant vector on Euklid.
At the end of class Maks told us to finish any one of those questions, that Paige listed in her post, by Monday. It doesn't matter if it's done by hand or by using Euklid. You can use this link to download Euklid onto your home computer. http://www.download.com/Euklid-DynaGeo/3000-2053_4-10279157.html It is only a 60 day trial but Maks said you could contact him by email and he will get you a password/code so that it won't expire.
Also, Monday will be a work period so that we can practice before the test coming up. See you all Monday!

October 3 Homework

So today we have some homework, Assigment 3 questions:
1,
2,
3,
5,
7,
9.
All on Page B-6

Vector Addition

In class yesterday, we learned about vector additon using the triangle method. Here are the notes for the section:



Then we did an example on it:


Steps for using the triangle method:
1. Draw a scale diagram of the first vector being added.
2. Draw a new coordinate grid at the end of the vector
3. Draw a scale diagram of the next vector
4. Repeat steps 2 & 3 if needed for additional vectors
4. Draw a thicker vector from start of the first one to the end of the last one.
5. Measure the distance and angle of the resultant vector, and you have your answer.

If anyone still wants help with this, here's a link to help, or you can ask me if you have questions. An important thing to remember is that if you take the vectors being added and play around with them, you will still get the same resultant vector

October 1

Hey guys

So i totally forgot to blog yesterday!! so sorry for the people who missed class yesterday and tried to check the blog to see what you missed.

So yesterday Mr. Maks was away so we had a sub. She was very nice and I liked her alot. We were supposed to work on the booklet Mr. Maks handed out to us and get as far as we could. I got passed excercise 2 and i had a little difficulty, but i'll just ask help from Mr. Maks today.

Hope everyone had a good night last night and got alot of the questions in the booklet.



Here's a math joke just for giggles:P



The Blogger for today just to remind you is Graham
