May 26th's and Today's Notes
As of the notes of Periodic Functions on May 26, we have learned and relearned of clarifying the amplitude, the period, and the phase shift.
To identify the amplitude, simply clarify the difference between the sinusodial axis and the maximum or mininum.
A period is determined through of the fraction 2(pi)/b. The parameter itself can be identified by switching 'b' with the period shown.
Parameter C is the phase shift. The phase shift moves the graph either left or right on the sinusodial axis, it is normally subtracted from x. The phase shift is identified as either a whole number or pi/c if the starting point value is less than a whole number.
We were also taught of the cosine function. But it bears a very close resemblence to the Sine function, so we'll only be learning of the Sine function this year. The difference from the Sine function is that it's starting point is pi/2 units apart.
For today's notes, we learn of Sequences, a list of numbers that follow a certain pattern. We learn of two types of Sequences, Recursive and Implicit. A recursive sequence, is a list of numbers generated by continuously adding the difference to the first term. Such an equation would be y= 3 ( n  1 ) + 4, the 3 would be identified as the difference. Take note that n would be rank. An implicit sequence is basically a list of numbers generated by a linear equation. More or less y = 3 n + 1. The difference in an linear equation would be the slope.
With that said, this scribe will now bid you adieu. As he is sleep deprived, the next scribe will be Don. Please, the person that is to take care of the scribe list, please update it regularly. This is also for anyone next year as well. If, the scribe list is used again.

Transformation of the Sine function
Today in class, we learned what each parameter in the sine function does.
This is what a sine function formula looks like:
but.. what does the formula mean?
Let's start with Parameter D:
 a (+) value shifts the graph upwards by
x number of units
 a () value shifts the graph downwards
so..if D = 2, the graph shifts up 2 units
if D = 2, it shifts down 2 units
Parameter A:
Parameter A controls the amplitude of
the graph
* The amplitude gets higher when the value of
gets bigger. A negative value will flip the wave
upside down, but the height of the wave does
not change.
Example:
the black wave is what a basic
function looks like
 the blue wave represents the function with
a negative A value (A=2)
the red wave represents the function with a
positive A value (A= 2)
Parameter B:
Parameter controls the width of the
graph. It also multiplies the copy of
the wave.
normal sine function : period = 2Ï€
so...B= 2 is the same as 2Ï€/2 or Ï€
* the value of B becomes divides the
normal sine function.
Example :
 black wave : sin(X)
 red wave : sin (2X)
Parameter C:
Parameter C shifts the graph
left and right
 a (+) value shifts the graph
to the left by x number of
units.
 a () value shifts the graph
to the right.
Example:
 black wave  represents the basic
sine function
 red wave  represents a positive C
value ( C=2)
 blue wave  represents a negative C
value (C= 2)
That's it for today's blog. I hope it helped you guys understand the today's topic.
The next blogger will be... Roe.

My Project Thing
for one of the questions (since my computer wont let me view past posts/videos, i am just remembering back to a question i remembered from matrices about trips between cities.
I will figure out the details once i get with my partner.
My second question is from the unit of probability.
On the board game you can move pieces diagonally forward.
a) determine the number of different pathways from the game piece to each of the squares on the other side of the board.
b)assume the player is equally likely to go left or right. what is the probability it will land on each destination.
My timeline is the same is chelsias

Debt. Equity Ratio = Total Liabilities  Mortgage / Networth
Lebron is married with two childen. He wants to borrow money to make a major purchase.
His financial advisor prepares a net worth statement for his family with the following.
Lebron and his family live in an $80,000 home on which there is an outstanding mortgage of $52,000.00. He owns a car valued at $20,000.00 and owes 12,000.00 on a 2year loan he took to buy the car. He has $5000 and a short term personal loan for $2500.00. The family has $1500.00 in a chequing account and another $3000.00 in a savings account. He owns a boat worth $5000.00

Today we learned that that net worth = assetsliabilities.
Assets is money you have or things of value that you own. There are three kinds of assets:
Liquid Assets: Money you can access easily (cash amounts)
SemiLiquid Assets: Longer term investments (stocks, mutual funds, or some real estate)
NonLiquid Assets: Material goods (cars, houses) you have to sell it to make money.
Liabilities is amounts of money that you owe. There are two kinds:
Short Term Debts: Must be paid in the next twelve months.
Long Term Debt: Payments that will take more than a year (mortage).
We also learned today that the Debt/Equity Ratio = (Total Liabilities  Mortage) / Net Worth
You want the outcome of the Debt/Equity Ratio to never be bigger than .5 or 50%. If it is even half a percent higher you will have a hard time finding a bank if you can that will give you a loan. But not is all lost, if it is larger than 50% you may try to get a lower loan, find the money in some bond or somewhere else, take a smaller loan then get another after, or even pay off another debtin order to get that percent 50 or lower.
There a few really good examples of this in the slides Mr.K has put up, so if you feel you need more feel free to also look there.
Wish everyone luck on tomorrows test :) and the next scribe is...Lamael

Personal Finance... YEA!
Alright, let's get this started with a concept I was stumbling with for a bit. I could not, for the life of me, understand why the formula for the feasible financial capital percentage one should consider when purchasing a home. For your information, the absolute maximum feasible percentage of one's income that should go towards their home is 32%. Here's a couple things to remember.
It's called the GDSR, and it's composed of a number of things. You've got your Monthly Mortgage Payment, your Monthly Property Tax Payment, your Monthly Heating Bill, and half of your Condo/Strata Fees. Now you lump that all together into one great big chunk and you divide it by your Monthly Income. The number that is generated will be a decimal, in theory. Technically, if you were using this formula on a house WAY out of your range, you'd get a whole number. Or, over 100% of your monthly income would be going to your house.
That's right! The decimal you receive is a percentage! And that is the percentage of your income that is going to your house. You want that to be under 32. The formula looks like this:
Perhaps you are thinking, "That's all well and good, but what if I'm missing a variable, smartguy!? Maybe I don't know my monthly mortgage payment, JERK!" Well fear not my fine, feathered friend. If you find 32% of your income, and subtract from it what you DO know, your answer will be what remains of your 32% income, or, what you have at your disposal for whatever variables you are missing. For example:
If I have $1000 a month for housing, my feasible income percentage will be $320. Let's say it's a house, BOOYEA, no condo/strata fees. Heating is %40 a month, property taxes are $60. BEAR WITH ME.... $40+$60 is $100, Therefor... $320  $100 = $220. I have $220 to spend on housing per month.
The other thing we covered today was the pros and cons of home ownership. For more information contact your local "Personal Finance" tagged slide... uh..(s)... Slides.

The next question I choose is this one
I chose this one because I failed my statistics test and this was one of the hardest things to do on the statistics unit in general. Normal curves were just a bit confusing. Okay so these are the questions im going to model my expert voices project on albeit a little more difficult and a little bit more different.

Thursday's Notes, DEV Project Tip
For the notes on thursday, May 14, we were reminded of how to calculate our GDSR. Or otherwise, our Gross Debt Service Ratio. Our GDSR will not allow more than 32% of our income to be spent or else you want to spend your time bored and hungry. Your Gross Debt Service is calculated by summing the monthy mortgage payment, the monthly property tax, monthly heating costs, and half of your condo fees if you're living in a condo. The sum of this will be divided by your Gross Monthly Income (this includes people who are living with you, unless they are minors).
The formula will be shown here.
In order to find out how much you can afford each month (the monthly mortgage), multiply your GMI by 32% and subtract the sum of the monthly payments with the product of the GMI and GDSR.
With this, we've found the monthly mortgage for this
Once finding the monthly mortgage, we can find the Maximum Mortgage Payment of an individual or a group of individuals. To calculate this we input this into the TvM Solver, the payment periods are set to monthly while the interest compounding periods are set to semiannually. Once we find the principle value or PV, we simply add it to the downpayment to get our MMP.
Example:
There are additional costs to buying a house though.
1. Appraisal fees
2. Inspection costs
3. Property Survey
4 Insurance costs for high ratio mortgages
5. Home insurance
6. Land transfer tax
7. Interest adjustments
8. Prepaid property taxes and utilies
9. Legal fees
10. Sales tax
11. Moving expenses
12. Services cgarges
13. Immediate repairs
14. Appliances
15. Decorating cost
To find the additional costs, clarify all of the costs and sum them.
A reminder tip for the DEV project.
If you're using slides, do not turn them into power point projects. Always use short, attractive bursts of information with a large amount of images to support said information. Sometimes even an image itself is good enough to bring out what you want to say. Don't be afraid to use a lot of slides.

IT'S a LATE scribe POST
Hi, Today in class the first thing we did was hand in the answers to our homework.Then Mr. K. went over the answer after we handed it in. After that we talked about the advantages of leasing and buying a vehicle.
ADVANTAGES LEASING
 Lower initial Payments
 Get to drive most recent vehicles (new)
 Can not modify the Vehicle
ADVANTAGES BUYING
 You own the vehicle it is yours
 You have an unlimited amount if kilometers
 You can modify your vehicle
Shortly after we talked about buying and renting a house. Renting is basic it is monthly payments( + hydro, water etc. if not included in rent). But you will never own the house if you rent it.
Buying a house is quite different. You must have a minimum down payment of 5% of the value of the house.
EX: A house is valued at $100,000 your minimum down payment will be $5,000
how? value(100,000)*minimum down payment of 5%(.05)
=$5,000
Then you have to get a mortgage. A mortgage is like a loan from the bank that you have to obviously payback but with interest.
EX: The mortgage will cost you $106,400
how? balance($95,000)+ total interest($11,400)
=$106,400
The Mortgage balance is what is left over from the total value of the house after the down payment is made.
Also Mentioned In Class
The GDSRGross Debt Service Ratio is how to find out he maximum amount of your income you can afford on a house (32%).This can be expressed as a formula:
GDSR=Mo. Mort. pmt.+Mo. Prop. tax+Mo. heating cost+ 1/2 of condo or strata fees
Gross Monthly Family Income
EquityThe part of the house you own.

Well I made a post last night.... but it didn't seem to publish. I was having a hard time publishing it.. kept getting an error message and eventually it said it posted... but apparently not. Anyways... lets see how close I can get to the previous post that never made it up.
Well we continued to use the same program through APPS then into Finance.
We also talked about Depreciation value.
Depreciation is the amount of value a thing loses. The depreciation Rate is how much value it loses per time period. weather it be week... month or maybe year.
An example would be if a car lost 10% of its value every year... and lets just say the car was worth $10,000.00, after one year the car would be worth $90,000.00. Now this is the part you have to remember. when it comes to the price after the second year, you cant just take 20% off of the initial price ($100,000). you have to take 10% off of the value at the end of the 1st year (the $90,000.00).
There are two ways of doing this... you can either make a chart that looks like ..
Year initial value End of year
1 $10,000 $90,000
2 $ 90,000 $81,000
3 and so on...........
OR,,,
you can use the formula I(r)^n
I=initial amount
r= depreciation rate
n=number of years (or whatever the time period is at which the depreciation value is based upon)
WE ALSO:
we also looked deeper into leasing. We discussed how when u lease a car... you are only paying for the part of the car u are using because at the end of your lease... u have to give back the car. Now when you give it back, it is not worth as much as it was when you first got it.
Leasing a car is like asking for a bite of food. You still get to taste it.... but you don't get the whole thing. You enjoy your piece, then give the rest back.
As I was saying before, the depreciation is the value of the car that you have used up.. and the value that u give back to the dealer is called the residual value.
Since you use up the depreciated value, you have to pay sales tax on that part. You do not however have to pay taxes on the residual value.
Much like today, we went over some of the Pros and Cons to both leasing and Buying.
Leasing a vehicle is good for someone who can only afford small monthly payments, who doesn't want to worry about dealing with trading in or selling a vehicle when they no longer want it or who likes to change vehicles often.
Buying a vehicle on the other hand is good for someone who can afford to outright buy a car, who used a vehicle allot (travels long distances, across town commute etc.) or who likes to make customizations to their vehicle.
That is about all the things we went over....
I already chose the scribe for today but i will just put it up anyways for record sake ( Eugene )
I apologize again for not posting it last night... i really thought it was up.

Leasing
Hey everyone! Today in math class, we learned about leasing. We started the day with the usual 'going over the homework' and then Mr. K put us right into the lesson on leasing.
From what I understand, leasing is when someone is giving another person either land, property, car, etc. to another person for a certain amount of time. Its like a rental agreement that can last for years. What also happens is that people who are leasing, have to make monthly payments for
•'depreciation'
•'sales tax' to that depreciation
• and 'interest on the unpaid value' of the item that is being used.
Depreciation means that there is a reduction of value in that item as time passes by. For example, the more you wear a brand new pair of jeans and as time goes by, the jeans start to fade out, decreasing the value of the jeans.
Sales tax is the tax that has to be paid for a section of that item that is being used. For example, a car that you decided to lease for three years, you only pay a portion for the car because you only use it for a certain amount of time and then you have to give the car back. During the time you have the car, you are paying taxes for the portion that you used.
Interest is when you pay at a particular rate for what you are leasing
When you are done leasing the item, You would either return it to the person that loaned you the item or you can buy the item. What this is called is 'Residual Value'. It's the amount (cost) of the being sold.
Mr. K also showed us a way to see how depreciation works with the calculator.
Ex. A car depreciates 20% per year. What is it worth in 5 years?
This is what it would look like on the calculator
What we did was you take 100% and subtract 20% from it, giving you 80%
Then we did 100*0.80 which equaled to 80.
What you would do next is you have to press on the multiplication button on your calculator and then it what would pop up is Ans* and then you punch in 0.80.
Press enter 4 more times to give you how much it would be worth in 5 years.
The car is worth 32.768 in five years.
The next scribe will be, K_Hannah (:

scribe post Friday May 8
Sorry for the late scribe post...
Scribe post May 8/09
Today we opened up the class by seeing a pink smart car with hello kitty on it, it was cute... in a "i would never do way" but cute.
We learned how to see how much of your savings and what interest you will have after a certain amount of months, years so on.
in the case that Mr K had given us the payments where made quarterly so for instance with the example he had given us..i had broke it down on the image below...
The next question we worked on showed us how to not only to find the monthly payment but to also find out the complete interest you received and how much it would be to pay it off..
a monthly payment of $8250 loan with a interest rate of 8.5% compounded monthly...If the loan is repaired in 2 years (24 months)
to determined the monthly payment we go to are tvm solver on our calculator under finance and fill it out like this...
the pmt (payment) amount was 376.52 because you are taking it FROM your money to pay it off.
To determine the total cost of Repaying the loan would be 376.52* 24
24 because of the 24 month payment
= 9036.48
You take that amount and subtract the principle value, so the value you started with .
9036.488250= $786.48
Sorry again for the late scribe post if anything is wrong with this scribe please comment so i can fix it!
thank you see you Monday!
next scribe is...Alvina!
(if Alvina had done it already then .....Katie!)

reflection #2 (vectors)
This is my reflection on vectors
This unit was one of the shortest ones i have ever done, i understood most of it other then the Parallelogram Method, and when all the questions were put into super complicated problems where words were switched around. That was the only time i was somewhat lost. Other then that i got everything i was so excited and proud, it was taught well and pretty easy understood.
:)
...sorry was late...

Credit Card Interest Rates
Hi guys..We've just discussed about our assignment and it was really interesting. We also discussed about Credit Cards and Interest Rates. There are 2 types of interest rate:
Nominal Interest Rate is the interest that the bank given.
For example: If the bank has 5% interest rate in semiannually, the Nominal Interest Rate would be 10%. It will be 10% percent because semiannually is half a year and annually get charged. Like:
05%(2) =10% (2)  represent a 1/2 year
and Effective Interest Rate is the rate that you actually charge on an annually basis and or paying interest on interest each compounding period.
Here are the Solution to get the Effective Interest Rate:
Effective Interest Rate = ( 1 + i / m ) ^m 1
Effective Interest Rate = ( 1 + 0.10 / 2 ) ^2 1
Effective Interest Rate = ( 1 + 0.05 ) ^2 1
Effective Interest Rate = ( 1.05 ) ^2 1
Effective Interest Rate = 1.1025 1
Effective Interest Rate = 0.1025
or = 10.25%
NOTE :
m  is the number of compounding period like:
Monthly (12), Quarterly (4), Semiannually (2) and Weekly (52)
i  is the Nominal Interest Rate.
! This website might give you some great ideas about Interest Rates and solution to your questions:
http://freeonlinecalculator.net/calculators/financial/effectiveinterestrate.php
In addition to, we also discussed about the "Rule of 72". The "Rule of 72" is a simplified way to determine how long an investment to take double, given a fixed annual rate of interest.
Formula of "Rule of 72" is:
Years = 72 / ( Interest Rate % )
Rate = 72 / Years

Compound Interest
Today, we learned how to calculate Compound Interest problems.
Compound Interest
is a system which adds the accumulated interest to the principal, such that the interest earned is based on that adjusted principal.
Here's the formula for calculating Compound Interest and what it means.
A = final amount at the end of the term
P = principle amount
1 = preserves original investment
r = rate in decimal number
n = number of times compounded
t = time in years
Knowing the formula, we can now calculate Compound Interest.
Here's an example.
Justin decided to invest $1000 for 2 years. The bank told him that the interest rate will be 5.25% and will be compounded semiannually. How much will Justin end up with after 2 years?
Solution:
TVM (Time Value Money) solver does all the calculation for us. Here's what a TVM solver screen look like.
N = time x number of times compounded
I% = interest rate in %
PV = present value
PMT = payment made to the account
FV = Future Value
P/Y = # of payments per year
C/Y = # of times compounded per year
the next scribe will be....
Jason. :)
