### sandra scribe day!

Last class we worked on some slides about interpolation and extrapolation.
Then we worked on some sequences, we went into some small groups.

Arithmetic Sequence:

- Recursive Definition:
An ordered list of numbers generated by adding a value continuously.

{/EDIT} An arithmetic sequence is when you continue adding the same number over and over again. For example:
5, 10, 15, 20, 25...
That is adding five to the previous number.

And to find the equation of the numbers the formula is Y = ax + b, so it would be like,
Y = 5x + 0 (used the sequence above for example).
If you're wonder how i got the zero, look at slide 8/13 for December 18th.
It's pretty much just
subtracting 5 from 5 because a = the first term and you subtract 5 from the first term.

Since the sequence is just adding 5, the common difference is 5, because there's a difference of 5 in each of the numbers.

I hope this is enough =)

sorry guys, i have no idea what im doing =.=''

### Scribe - Thuan's version

Today in Math class..

we started off by Mr K talking about interpolation and extrapolation.

-Interpolation

 a. the process of determining the value of a function between two points at which it has prescribed values.
 b. a similar process using more than two points at which the function has prescribed values.
 c. the process of approximating a given function by using its values at a discrete set of points.
Source:http://dictionary.reference.com/browse/Interpolation

-Extrapolation

to estimate (a function that is known over a range of values of its independent variable) to values outside the known range.
Source: http://dictionary.reference.com/browse/Extrapolation

Then Mr K started putting us into 4 groups, then he gave us questions on the smartboard. After we were all done with the questions we discussed the questions and how to get the answeres and why they were answers for example the first question was to find the Equation which was Y=-469.30143x+7599.39712 I dont know how you guys got the answer because I use a different calculator so i cant really explain how i got the answer. Basically we got through all the questions but what I learned this time when I was working with my group I learned what slope and y-intercept really means and how to get it.If the equation is written as y= ax+b, the slope number is the number "a"that is multiplied on the "x", and "b" is the y-intercept. Yet again I dont know how to show you guys how to do it on the calculator because I have a different one. In our case the slope is -469.30 and our y-intercept is 7599.39. What does those numbers mean? the slope means the price of the cars decrease every year by \$469.30 and the y-intercept means well.. i forgot what it means but atleast I know how to get the answer. =D... thats a smiley face

Next Scribe will be....Yet Decided

Just kidding its Sandra just to start things all over again

Earlier beginning of the class we talked about digital ethics which is you don't have to post any pictures ourselves because we being so careful to our own privacy and we can only use our first name and if you really wantedto have your own graphic association image with your posting . you may also used avatar. a something represent you but its NOT you..

Later on, we also talk about the y-intercept and what is the meaning of it be by using graphic calculator. This are the steps how to used the graphic calculator by solving the y-intercept:
• When we used the graphic calculator we press STAT and look for the EDIT and list they points.You should enter the data in the list. To get to the list (1) one or list (2) two. To clear the list press the up and down button, clear and enter your data.
• when your going to create a scatter plot you should press 2nd function, y=, and enter. Choose scatter plot, x list and y list.
• To create a regression equation. Press STAT, ARROW to the LEFT and move to the CALC and pick your regression and then press 2nd function (1)one, comma, 2nd function (2) two and comma.
• Press VARS, arrow to the right and move to the Y-vars ENTER to the function and ENTER.
This are the types of regression:
- linear
- exponential
- sinusoidal
- logarithmic
- power

we also correct our quiz in the end of our class. we talk about the y-intercept and also how to write the equation of the line. do you know the meaning of interpolations? Interpolations means is to estimate values of(data or a function) between known values.

This are the things that i learned in our class today. My scribes not too short but in this post you can easily understand by is step.

The next scribe will be THUAN. (^_^)

### Is math a challenge?

What wonders have you experienced in math lately?

I forgot about the scribe, the next one will be Cachel.

<-- Enter these values, and your window should fit just right. Press Y= and go down to Y2= and enter 25. This will make it so that on the Y axis ther will always be a line at 25.
Press GRAPH again, then press 2nd and CALC (above TRACE). Then press 5 which is intersect. Move your right arrow down to where the lines intersect, (your X should be around 14.9 and your Y 25.7) and at the bottom of the screen it should say First Curve? Now you press ENTER and it should now say Second Curve? Press ENTER once again and it should say Guess? Press ENTER for the last time, and it should say Intersection, and now your done. Notice how your Y=25 and your X=15.04. That means that the bacteria that is present is 25, and the hours it took to get there is 15. The next question is asking to state the largest value and the smallest value of the domain. (Domain is the X axis). To do this you have to 2nd CALC and then press 2 because you are looking for zero. Then you press the right arrow to scroll down on your line until you get to the X axis. When you are there, the coordinates should be around 19.9 for X and .834

Sorry for the late post Mr. K and fellow classmates!
Regarding the little quiz last Friday, was it
just me or were you all confused as well?
I honestly did not think that we learnt how and what to
use for those kinds of situations, even with common sense
added to it, it was difficult.
So I can't really help anyone on understanding it.

Although, I did understand the things going on
in yesterday's class. The worksheet that he gave us
was to help us learn how to insert graphs
and how to label it by using information given to you.

Mr. K specified (the post below) us to make a multiplication
table allowing only cell A2 to be a number, while the rest are formulas.
This being the part where absolute cell reference comes to play.
If you guys haven't remembered, absolute cell reference is when you
put dollar signs on either side of the cell name's letter that you want or would
need to be absolute, leaving the number out and is to be repeated

when you click and drag the little blue square in the corner to the desired spots.
Also, we were told to fancy things up with colours and
make a Sheet2 showing all formulas used.
That's all I can think of writing at the moment.

carefully!
And keep our blog neat!

### SS06 Multiplication Table

Create a multiplication table that provides all answers from 1x1 to 12x12. You may type the number "1" into cell A2 but not ANYWHERE ELSE. You may not type any other numbers into the spreadsheet; every other cell must contain a formula.

Put your first name in cell A1.

Colour the columns or the rows to make the spreadsheet more attractive and easy to read. When you are done "hand in" your assignment by publishing it and leaving a comment here with your name on it.

REMEMBER: You must also create Sheet 2 that shows all the formulas you used.

### Today's Class (12/04/2008)

Hi! this is Judith and today, we were in the lab and we did new spreadsheets. The first one was that we had to work with a partner. It was called ss03 Smart Spreadsheet! It was about a teacher grading his students about finding their final mark. We were supposed to solve it if the Assignments, Project and Tests were 30% each or if the Assignments were 30% and the Project was 20% and so on. Then we had to find the Class' Average of each and the final marks.

Then we had to do a second one called ss04 scratch which we just had to it ourselves. It was about a local greenhouse pays double time for any hours over worked per week during summer. Then we had to create a spreadsheet about it which was ss04 scratch that calculates the gross pay for each employee and the total weekly gross pay for the company. Then, theres a 2nd one and its about a rectangle finding its length, width, perimeter and area.

Then we went to tutpup.com to play games and then we were shocked that we had to leave tutpup already because we didn't got a chance to play a game and I think only one of did only and I don't know if we went to tutpup first or we did ss04 scratch afterwards and it was fo homework if you didn't finish but yeah thats what happened to day!

Mr. K told us that at friday which is tommorow, monday and tuesday that we'll be at the lab then at wednesday that we'll have a test about spreadsheets at the classroom!

And we'll just pick the scribe tommorow because I'm not sure who didn't do it yet and did it already!

So see you guys tommorow!

(*sorry if the scribe doesn't make sense its because I don't write good and
that descriptive so just ask one of us in the class if you didn't understand
the scribe tommorow!)

### here's my spreadsheet 01 homework

this is my homework for today..

(^_^)....cachel

### Todays Class

Hi everybody Coralee here tell you what we learned in class today

Today was pretty laid back we first talked about how to properly get a spreadsheet on t the blog an to do that you need to go to share click on publish to the web click publish once your spread sheet is published copy the URL and past it into the assigned spot on the blog Mr. K has set up.
Then we talked about posting to the blog and tags to properly put a post on the blog you need to name your post and have 3 tags your name if you are the scribe you will need scribe or were just asked to you will put BOB and then the last tag will be the unit so it will look like this

Last we were all shocked when he handed out a quiz but it was just about formulas in spreadsheets and how to write them and solve them pretty easy stuff.

e.g.

Add A5 and B7 to find B8 = A5 + B7
Subtract G5 from G6 = G6 - G5
Average G4 to G9 = Average ( G4:G9)

These are some examples of formulas that you will be using in spreadsheets and this is how to solve them lets say A5 is 87 and B7 is 8

so to solve it you would add 87 and 8 to Find B8 in this case it would be 95 so B8 would be 95

Some important symbols you will need to know :

* -this is the multiplication symbol it is located above the eight on your keyboard
= - you will need this to complete your formulas

+ - The plus is for adding of course

- The minus for subtracting

and i don't really know what else to say so hope its helped a little and that is pretty much what we have learned in class over the last week.
Oh and there will also be some slides below this post on today's class

And the next scribe will be Judith

See y'all tomorrow

### how to use a TI

This is Caitlin, it's November 24 and here are some points on how to use your calculator if some of you missed the class or didn't take notes.
.to get to your list you just press STAT then ENTER
.T o make a scatter plot you press 2nd y= then ENTER
.In linear regession you go in to STAT hit the arrow key > and go into CALC and go down to #4, then put in 2nd 1,2nd 2, then you hit VARS > ENTER

For line that best fit
y= then graph 2nd trace #5

### Are there?

Lessons from the Geese?

## Thursday, November 20, 2008

yesterday we worked on the worksheet we got on tuesday. for the most of the class we also tried out our calculators. anyways yesterday he assigned page 150-151 questions #1-5. this is one of the classes that we learned alot about stuff.

ryan
functions and relations
chapter 3

## Tuesday, November 18, 2008

Today we learned about alot of things.

We learned that if a rule says that it can only give you 1 possible answer than it is a function. For example if you had 2 ordered pairs and you put them into a coloumn like this:

2 5
7 1

Now say there was a line connecting the 2 and the 5, and a line connecting the 7 and the 1, the line is suggesting that each pair has only one possible answer and is therefore a FUNCTION. Now say the arrangement of the lines and the numbers were still as they were, but now there is a line connecting the 7 to the 5 as well, that is suggesting that one ordered pair has 2 possible answers, and is now considered a RELATION. A relation is something mathematical that can give 2 or more possible answers. A function is something mathematical that can only have 1 possible answer.

We also learned about Range. Range was a fairly easy concept which is used to show somethings boundaries. For instance on the little test we got with the questions about the drink machine at work. That graph suggested that the most amount of drinks in the machine at once could be 400, and the least could be 100. So simply, the range of that graph or those drink machines was 100-400, which in math terms is shown as [100-400].

Another thing we learned about was Function Notation. Function Notation is just a different way of putting an equation. If I made up a rule in my head that every number I heard I would add 1, then the rule would be x+1. To put this in function notation, just basically do this : f(x)=x+1, just like what we learned with Dr. Eviatar. Then you could fill in the equation by substituting x ( for example, 35) so f(35)=35+1 which would equal 36. so f=36, but its better to use the first equation I mentioned because it displays the input and the output, as suppose to the second equation which just shows the output.

A small thing we learned about is the Shadow Method. What that is if you had a pen and a marker and you flashed a light on them vertically, the pen's shadow would be longer because it is longer than the marker. It can also be used on a graph to find out information. You can also use the Shadow Method in different directions and not just vertically, to find out more info.

We learned about variables too which are jus symbols like X and Y replacing unknown numbers in an equation.

We also learned about Domain but I didn't get notes on that unfortunately because Michelle told me I was the "Scribe" so late!!!!!!!! If you dont understand this post, and you probably don't then sorry and ask the teacher tomorrow.

And the scribe for tomorrow will be..................................................................................................................PAIGE, no actually, MATT, no actually, RYAN! YES, RYAN YOU ARE THE SCRIBE. Ok bye.

### Where are we

BOB

the things that i don't understand are:

the line of depression, sin, and cosine law, and when to use it when doing Trigonometry.

don't really remember things in Coordinate Geometry.

and also don't understand and remember things in Relation and Function.

### Where Are We Wordle

I took all the BOBs you wrote. Copied the text and pasted it into Wordle to look for patterns in what you had written.

This wordle was generated by the first 7 BOBs written tonight.

Tell me, what do you see?

### hiiiiiii

Soo,,, I'm having trouble with the geometry stuff, like the whole thing.
Trigonometry is pretty easy, I think, don't exactly remember.
And, with relations and functions, I think I kinda get it, if we go over it a bit more.

### What I don't understand for...

TRIGONOMETRY

- the line of deperession
-sine law
-cosine law

and COORDINATE GEOMETRY

-almost everything

and RELATIONS AND FUNCTIONS

-almost everything too!

And I didn't have any trouble for the unit about the numbers.

-Judith

### where are we now?

The thing that i really don't understands are:

• trigonometry, the angle of elevation, depression, and some word problem that i don't understand..
• how can I know if were going to use the sine, cosine, and tangent...the SOHCAHTOA...
• the relation and function
That's all, the topic is really confusing..

### Where are we?

B.O.B.

I thought Dr Eviatar tried to help us with Trig but couldn't reach us, after I got tutor I could not believe how easy it was to learn, Sin A over a. coordinates i found very easy i didn't have any trouble with it, same with number systems. i think the class should go over Trig again to make sure everyone understands.

### cait

hi

TRIGONOMETRY!

For me I felt bombarded with all the data we had to memorize. Here's what I don't fully understand.

-How do we tell when we has to us Sin or Cos .
-"Line of depression" to "rise" ... or something like that
-How do we take a word problem and put it into a diagram

I get so lost with all this information, I found it was too much and too complicated because everything is linked together.
I hope that helps ....

-Michelle-

### 111708

i don't understand Trigonometry.

(why can't i comment on posts?)

### Michelle / scribe / relations and functions

Today in class it was a "reintroduction" to Mr .k. We learned more about the blogs, and we get to make a "fresh start". Here are 3 necessities you need to display while posting a blog:

Write that it is a scribe
Write the unit we are covering

Also if you have your first and last name as your display name CHANGE IT. You need to keep your identity safe and protect your self.
During class we were given a review sheet on relations and functions. We were given to graphs and had to find what graph was most realistic, for example:

Every morning at camp, one of the scouts hoists a flag on top of the flag pole. The graphs below show the height of the flag as a function of time.

You were then given 6 graphs and had to choose which graph was models the situation correctly.

Another graphing question was your typical X, Y graph with given data to explain the situation. We had to give an logical guess and decide how to "time of day" related to the "number of cans"

This was basically all we covered. It may not seem like a lot but all of the students and Mr.k had to re connect and get on the same page as far as to where we are with our math.
*homework* .... post what unit to struggled with the most over these past 4 units.

-Michelle-

### What is the stuff i dont understand

What i dont understand out of the year so far would have to be trigonometry its to confusing

### Digital Ethics

Blogging is a very public activity. Anything that gets posted on the internet stays there. Forever. Deleting a post simply removes it from the blog it was posted to. Copies of the post may exist scattered all over the internet. I have come across posts from my students on blogs as far away as Sweden! That is why we are being so careful to respect your privacy and using first names only. We do not use pictures of ourselves. If you really want a graphic image associated with your posting use an avatar -- a picture of something that represents you but IS NOT of you.

Here are a few videos that illustrate some of what I want you to think about:

Two teachers in the U.S.A. worked with their classes to come up with a list of guidelines for student bloggers.

One of them, Bud Hunt, has these suggestions, among others:

1. Students using blogs are expected to treat blogspaces as classroom spaces. Speech that is inappropriate for class is not appropriate for our blog. While we encourage you to engage in debate and conversation with other bloggers, we also expect that you will conduct yourself in a manner reflective of a representative of this school.

2. Never EVER EVER give out or record personal information on our blog. Our blog exists as a public space on the Internet. Don’t share anything that you don’t want the world to know. For your safety, be careful what you say, too. Don’t give out your phone number or home address. This is particularly important to remember if you have a personal online journal or blog elsewhere.

3. Again, your blog is a public space. And if you put it on the Internet, odds are really good that it will stay on the Internet. Always. That means ten years from now when you are looking for a job, it might be possible for an employer to discover some really hateful and immature things you said when you were younger and more prone to foolish things. Be sure that anything you write you are proud of. It can come back to haunt you if you don’t.

4. Never link to something you haven’t read. While it isn’t your job to police the Internet, when you link to something, you should make sure it is something that you really want to be associated with. If a link contains material that might be creepy or make some people uncomfortable, you should probably try a different source.

Another teacher, Steve Lazar, developed a set of guidelines in consultation with his students. You can read them here.

Look over the guidelines and add the ones you like in the comments section below this post; either from one of Steve's students or one of your own. I think Bud's suggestions are excellent. We'll be using the one's I highlighted above as a basis for how we will use our blog.

Cheers,
Mr. K.

okay ummm... this is my first post so it may suck.
On Friday we learned how to measure a slope and and the slope of the perpendicular.

The theory for finding the slope is Rise over Run. The rise is the vertical line, the run is the horizontal line. Once you have the slop you can then find the perpendicular slope. The theory for this is dividing point A and B, then "flipping them around" (meaning the fraction) and changing the fact if its negative or not.

I think that's it ... it was basically just a recap of Thursdays class, so this is nothing new.

### Applied Math 20S (Fall 2008): Slides October 16th

Applied Math 20S (Fall 2008): Slides October 16th

A Simple Worded Recap.

So, what we basically need to know at the moment:
- a (-)negative and a (-)negative is a (+)positive.
- To get the perpendicular slope, you flip
the fraction and change the sign.

Now, definitions.
Slope (m) - RISE over RUN - Line segment of an angle between a given straight line on an x-axis coordinate.
Reciprocal - AKA multiplicative inverse - A number related to another in a way that when multiplied together their product is 1. For example, the reciprocal of 7 is 1/7 ; the reciprocal of 2/3 is 3/2 .
Perpendicular (Upside down T) - Lines that meet at a 90° angle.
Parallel (||) - Two lines with the same slope that never meet.

As you should have already seen, the symbol
for perpendicular and parallel make perfect sense.
T(upside down) two lines that can meet,
|| and two lines with the same slope that never meet.

I've also learnt something today...
That the colour YELLOW is deathly blinding!

Also, for those who are curious of
how many E's Thuan's account name has;
there are exactly 169.

### October 2 2008.

Since no one has written a blog response, I will.

Yesturday (October 2 2008) we did some questions on coordinate geometry,
our homework was exercise 1, question 1-5, 8 and 11.
We should all understand how to do this, its simply graphing a shape or something,
on graphing paper, using coordinates.
In order to use coordinates, you have to draw a BIG + on your graphing paper,
and label the lines connecting it 1-8 or what ever numbers you want.
You use the number to guide you, say you have A(-8, 4) you would use those numbers,
and connect which ever lines those numbers were on.
well thats all, good luck.

### To my students ...

Hi,

By the time you read this you will already have heard from Mrs. Ingram that I will be away from school for an extended period of time. 10 weeks to be exact. I'll be back on November 17.

On August 18 we had our fourth child, a little girl. Her name is Sadie. My wife and I discussed this a lot. As this is our last child, late last week we decided together that I would take a parental leave of absence.

I must admit I had very mixed feelings about taking the leave of absence. We began learning together and were off to a wonderful start with much hope and promise for the semester ahead. That hasn't changed. You are all capable of being the person, learner, mathematician you imagine yourself to be.

I have always believed that anyone can learn math, even the most advanced math, as long as they see themselves as able to be successful. So much of your success, in school and in life, has to do with believing in yourself; having confidence in yourself. See yourself as a success and you will be successful; in this and in all things.

In my absence you will be learning from one of the finest teachers in our school, yet don't underestimate yourselves. You can also be the finest teachers of each other. Just making the effort to take on that role for each other will deepen your learning and make you better students. You are your own best teachers. Continue to work together. Teach and support each other. And watch yourselves grow into the finest mathematicians in the school.

Mrs. Ingram is a wonderful teacher, I've worked with her for years, I know. Trust and lean on her, and each other, and you'll go far together.

I'm going to spend the next little while just being a dad to my kids. In the meantime I'll be poking in on the blog to see how you're all doing.

Take care of each other. And learn hard.

Mr. K

### 09.04.2008 Applied Math

A 90 degree angle is called a right angle.
Any angle greater than the right angle(90 degrees) is called the obtuse angle.
Any angle smaller than the right angle is called the acute angle.

We reviewed how to find angles and sides using SOH CAH TOA.
SIN = opposite over hypotenuse

The hypotenuse(the longest side) is the opposite of the right angle.

All angles of a triangle equal to 180 degrees.
Example:

To find which angle belongs to which sides(usually the lower case letter), it's the opposite of the angle (usually uppercase letter).

Example:
