Blog of sept 30th, 2008

On this day we started by doing the #13 mental math, after that we went over exercise 2 scale diagrams that was homework.

On #4 the words "bounce back" are upside down showing that the ball goes back. After the ball is thought at the wall it will come back 25% of the way (75% decreased).

On #6 it is a friction vector, it show that a go-kart running on the motor will go the hole way, but the friction will try to stop it sooner.

All this is for is to show that a go-kart can go all over the place, we learned that if you move the arrows in different spots in will always go to the same spot.

We started to learn about Resultant Vectors.

Sept 29- Vectors

OK...so I am having a little bit of trouble with this so bear with me.

Vector- anything with a magnitude and direction. (much and which way)

eg. west wind of 40 km/h

Scalar- anything with just a number

eg. shoe size because it doesn't not have a direction to go.

Questions 4. The equal sides are UP and TR and PR and UT. You always have to have a line WITH an arrow over top of the letters to represent a vector. Without the arrow it is just a line segment.

This was our notes for today. Mr.Max showed us how to use our protractors today to portray a vector.

This picture represents the 3 ways of writing direction.

The first way, 41 degrees N of E means the you go 41 degrees north from east.

The second way, N 49 degrees E means you start at the north and go 49 degrees to the east.

The third way, the Bearing Method means you start at the North, 0 degrees, and move clockwise until you get to you point.

For our homework, you must finish Exercise 2 and complete the following chart.

Vectors

Mr. Max is still away today, so we are suppost to work on and finish exercises 1 & 2 for mondays class.

Here are some links to websites that may help with vectors:

http://www.tech.plym.ac.uk/maths/resources/PDFLaTeX/vectors.pdf

http://physics.about.com/od/mathematics/a/VectorMath.htm

Vectors and Scalar

Difference between Vector and Scalar:

Vector: have length and direction
ex. 30 m/s southeast

Scalar: just numerical, they have no direction.
ex. 4 kg

Here is a website that has all kinds of vector and scalar stuff:
http://http://quarknet.fnal.gov/toolkits/ati/vectors.html

Practicing Vectors

Today Mr. Macksymchuk is away and we are supposed to work on the booklet that he left for us to work on while he is away.

All of Excercises 1 & 2 on vactores are due for Monday.

We are to teach ourselves these lessons from looking at previous blog posts other classes have created. Mr. Macksymchuk has created a few links for us to access theses archives of vectors in the "links we think are worth seeing" section on the side of the blog.

We are to use EUKLID of graph paper for these problems.

Also i reminder to bring a ruler and protractor for class in the next few days.

Tomorrow (Friday) the scribe is Patzer.

Here is a nice picture of a "math nerd" to modivate you to master those vectors!

New stuff today!!: Vectors

Starting tomorow, bring rulers, protractors, and graphing paper! Today, we learned about EUKLID. It is a 2D geometry plotter that you use with vectors. IT IS PERFECT, NEVER WRONG (so says Maks).

Vector: a quantity possessing both magnitude and direction, represented by an arrow the direction of which indicates the direction of the quantity and the length of which is proportional to the magnitude.

Matrix Test Review

Today in math we started off with a mental math that proved to be quite challenging for myself and a few other students. One question had to do with multiplying fractions. I was and still am confused about that.
Our test is tomorrow so remember that you can make a formula sheet that is double sided to assist you in the test. The formula sheet has to be made by you and on 8 1/2 x 11 paper. This encourages you to study and ask the question, "What is he going to ask us on the test?". Also make sure to not waste your time on the test and read instructions carefully.
The content on the test can be divided into four parts. The first being the introductory material like the definition, vocabulary, and how to use your calculator when working with matrices. The second part contains the matrix operations like addition, subtraction, scalar multiplication, and matrix multiplication.
The third part will be on transition matrices and the fourth on networks. The following is what we did today in class. They are examples of a transition matrix and a network matrix.

More Network Examples

Friday in class we started off with mental math, which was quite interesting. We then went on to do some more network examples:

This example shows the number of DIRECT ways to get from one city to another. For example, if you wanted to get from Winnipeg to Brandon, there would be one direct way, but if you were to go from Brandon to Lynn lake, there is no direct route. We then found the number of ways you could get from one city to another goin through one town, and so on. The graphing calculator example shows the number of ways you can get from one town to another going through 2 other towns. An easy way to tell is if you take the original matrix and raise it to the 2nd power, and so on.

We then did another example based on an old provincial exam:

For those of you that are still having trouble with the transition matricies, here's another example for you:

This is question 5 off exercise 6, and it starts off like this:65% of the fitness club members will also use the pool, 78% of the new members will use the pool, 59% of new members will use the fitness room

Using those percentages, you then have to write a matrix showing the expected use of the fitness room and pool. Then in B) you have to show the distrubtion of old and new members. Then in C) multiply the answers in a and b to find out how many members will use each facility after the pool is done.

If you still need help with this, exercise 8 will help with the networks, and excercise 6 will help with the transtional matricies.

REMEMBER: TEST TUESDAY, SEPTEMBER 23rd.

On thursday September 18 we started off class with mental math

September 17, 2008

Today, September 17, 2008, we began class with mental math. A great way to get your brain working.


Next Mr. Max gave a Quote :

Omnipotent means having very great or unlimited authority or power.

Then Mr. Max went over Exercise 6: Transition Matrices (#3). Here are the notes for that question:

For (c) take Matrix A and multiply it by Matrix B to get Matrix C.
Take that Matrix C and multiply it by Matrix B to get Matrix D.
Then take Matrix D and multiply it by Matrix B to finally get Matrix E (the answer).


Last but not least Mr. Max went over how to Test for Stability.

Question: How do you know how big of a number to use?
Answer: Trial and Error


Homework:
Exercise 6: Transition Matrices (#5)

Yes, Yes, Yes....Emphatically Yes!!!

Most recently, and apologies for not acknowledging their work in class, both Stanick and lissa~* have set an extremely high bar for achievement with respect to expectations on the blog....



If you haven't read either post, read Stanick's here and lissa~*'s here. Particularly, what I like is that they're both different and unique in their own way, but entirely effective. I especially would like to acknowledge Stanick's attention to detail and excellent ability to explain (and therefore understand) matrix multiplication as well as lissa~*'s sense of humour... (A required element of ever taking a course with me, in my opinion)



The rest of you should pay attention to some of the things done by these fearless leaders...As I said, they set a high standard. I'm surprised that no one has left them any comments yet, but I'm sure that will change soon....Be optimistic, it's more fun than being Eeyore...



I must really like you guys to share embarrassing stories with you in class. Truthfully, I do really like you guys. We're going to have a great semester together.



Cheers,



RM

Sept.16 2008

Its Tuesday afternoon. Its an early dismissal.

Today we started the class with mental math. It was extremely hard.

Then Mr. Max did an homework check on question number 2 on exercise 6 on Transition Matrices. There will be no more homework checks.Only if Mr. Max gives us a separate sheet and tells us that it will be checked for homework.Then we went over question 2 together as a class.


Here is the answer to question 2. I hope i did it right!


There is number two.

Good Luck!!

September 15th/2008♥

Today is September 15th/2008...a monday:(. Math should be pretty exciting today!, but we will see :P! We started this lovely afternoon off with mental math. It was a decent one except the question, "What is half of a third of a quarter." I found it to be hard and confusing! The answer was 1/24..it was pretty easy once we were taught how.






Mr.Max then showed us the answers for question #4 on exercise 5. That was the last bit of practice for matrix multiplication.






-Cough Cough...do up the fly...Cough Cough- haha!

We then started learning about transition matricies :O!








So that is a recap of today! We will be learning more on it tomarrow.
Remember everyone...Exercise 6 # 2 is due for tomarrow!
Have a great Monday night:D

Matrix Exercise 5- 2,3.

Sept. 12th 2008.

Hey everyone, today we corrected Exersise 5 questions 2, and 3. I'm having a little trouble with this so bare with me as i try to explain it.

Question number two gives us a diagram of the two types of factories that produce kitchen and bedroom suits. The corporation has 3 factories of type A and 8 factories of type B. Kitchen suites sell for $1500.00 and bedroom suites sell for $2200.00. Now that we got all the information we can now use a matrix operation to determine the questions they gives us.

We have to find the weekly production of kitchen and bedroom suits.

If you look at the top of the notes you notice K and B in the rows, that stands for Kitchen and Bedroom. The A and B in the column stand for Factory A and Factory B.

We have a 2x2 matrix and a 2x1 matrix. The twos on the inside match so that means we are able to multiply these matricies. The numbers on the outside which are 2 and 1 mean we will have two rows and one column in this answer. So you do the multiplication and end up with the answer K=170
B=240 (with brackets)

Now, we are asked to find the total market value of the goods purchased.

So, we know for the Kitchen suites they sell for $1500.00 and the Bedroom suites sell for $2200.00. Which makes a 1x2 matrix.

You experiment now with these too see if you will mulitply them in the order of (2x1)(1x2) or a (1x2)(2x1).
It seems possible with the (2x1)(1x2) because the ones match in the inside so that means you are able to multiple them and come up with a two by two answer. But in this case, it is nonsense!! Two of your answer in your 2x2 matrix are numbers that don't make sense, don't exist, won't help you. What you need to do is flip the question around so you are multipling (1x2)(2x1) so you get a 1x1 answer. The total cost of kitchens and bedrooms is $783 000.


Now questions number three does not give us a matrix diagram so we have to do that on our own. When you are reading the question to make writing a matrix easier writing
down little notes like what Mr. Maks did helps in the end.

So, nine two story houses and six bungalows.(For those who don't know what a bungalow is, it is a one story house.) One two story house needs 1600 units of materials and 2000 hours of labour. One bungalow requires 1500 units of material and 1800 hours of labour. Labour costs $12.00 per hour and materials cost $20.00.

We first need to find the totaly units of materials and hours of labour needed to complete this job site.

With the proper matricies in the proper order as shown above we are able to get a 1x2 answer of the units of materials and hours of labour.

Second questions asks us to dermine the cost of building a two storey house and a bungalow.

What Mr. Maks was showing use was that multipling the 20 to the 1600 makes sense because they are both units of materials but multipling the 12 and 1500 is nonsense because one of them is units of materials and the other number is hours of labour. Doesn't match and doesn't make sense. You have to flip it around to make it a 2x1 matrix so you are able to multiply it correctly and get a 2x1 answer. The cost of a two story house and a bungalow. Add those two numbers and you get the answer to your last question. What is the total cost of developing the site?

I hope this helps anyone who missed this class or didn't understand it. If you have any questions please ask me and will will gladly help!

Random Fact from the 1500's

Houses had thatched roofs, thick straw piled high, with no wood underneath. It was the only place for animals to get warm, so all the cats and other small animals (mice, bugs) lived in the roof. When it rained it became slippery and sometimes the animals would slip and fall off the roof. Hence the saying, it's raining cats and dogs.

So, yesterday we worked on some Matrix questions, that were in the package we got. We went through Exercise 4, # 2 and#4 which helped me alot. We than worked on our practise post, which was basically some free marks if you did it. The reason for the practise post was so that everybody could learn how to upload images and whatnot.

*In the words of Mr.Max " Just because you can doesn't mean you should. Matricies are non sensable"


INVITATIONAL CONVERSATION: Do You Think We Should Be Getting Homework?
--Mr. Max thinks that us students shouldn't be doing more than an hour of homework a night.
what do YOU think?
I definitely agree with Mr.Max, too much homework is a brain overload! Plus when your buisy with other things such as sports, working, and what not it tends to be alot!



--->Due for tomorrow: Exercise 5


Now, since it is September 11th, I would like for everybody to take a moment of silence and appreciate our life in Canada and the freedom we recieve everyday. Be Greatful for our lives! And remember those who have past away in tragic events such as this particulare terrorist attack that have changed the lives others forever

Hey everyone!
This is my practice post for September the eleventh. It's not everyday that you get marks for posting absolutely anything. Wait, that’s not the cool part. The post can be about everything and anything. So my practice post is going to be about me. Isn’t that great?! Awesome is more like it. Here is goes… I like Wal-Mart. Who doesn’t? For a moment there, I thought I was going to be conceited for a bit. Just kidding!

Practice Post-Math Poem

A Math Poem
Math can be a wondrous rhyme.
Makes students go round and round all the time.
You can design equations to make shapes.
Or you can memorize them like an ape.
Sometimes you can monkey a solution.
This may cause a revolution.
But there really is no absolution.
Someone will always want to see the proof
And then will discover it was a spoof.
Then comes the day to put it on the board
Using old-fashioned chalk for the lord.
The prof will check for glitches
And look for funny variable switches.
Maybe you're lucky and maybe you're not.
But if you aren't you'll be on the spot.
So kiddies, learn your calculus well
Or else the prof could ring your bell.

Mr. Macs has taught us alot so far in this class. I feel that all the stuff he has taught us on matrix is really helping out alot of us so far. I think that all the work he gave us in the booklet handed out really helped me learn alot more on my own. I understand matrix pretty good right now and I'm pretty happy with what I've learned.
