There are a number of ways to approach the sinusoidal/periodic function. We were taught to use either GRAPHMATICA or a graphing calculator.
The periodic function equation is y=Asin(Bx+C)+D and that is what you will input into the software of your choice.
A=Amplitude
B=Period (formula for period P=2(pi)/B)
C=Phase shift
D=Verticle shift
Here is a site that demonstrates those values (very usefefull to play around with it)
-http://www.ronblond.com/M12/sc.APPLET/index.html
If you are given the sinusoidal function(periodic function) and want to graph it using a calculator
1. press[mode] and make sure that it is on radian NOT degrees
2. press [y=] and input the formula Asin(Bx+C)+D (substitue numbers)
3. press [graph] and behold the squiggly lines
-you may want to adjust the windows setting to get a better picture
If the information is given in tabular data then you will have to use something called SinReg
1. press [stat] and put the data into a list
2. press [stat]-> calc then go down to something called SinReg
3. back at the home screen put in SinReg,L1,L2,Y1
4. turn on the stat plot ([2nd y=]) and press graph
And that my friends is periodic functions in a nut shell.

Exam review
Hey everybody no one posted this exam review from last week so I thought I'd put it up.
(plus I need to get some posts in, get that blogging mark up).
Good luck tomorrow...

Today we reviewed for our exam that is schedualed for Monday June 8th, 2009 and tuesday June 9th, 2009. On Monday June 8th, our exam consists of two units, Periodic Functions and Design and Measurment. On the second day of our exam, our exam consists if the remaining six units which include; Matix Modelling, Vectors, Statistics, Personal Finance, Sequences, and Probability. Today in class we reviewed the units, Periodic Functions, and Statistics. Here are the slides that were covered in these units:

Hello everyone. Just to remind you, even though it is not needed, there are 7 days exactly until our exam. I hope you are all ready for it.
Today Mr.Maks recorded the lesson about what we will see on the first day of our exam, explaining "Applications of Periodic Functions".
He gave two approaches, or the two types of questions we will have on the first day. The first being given information to use, and the second will give you information that you will have to use the regression function or the "SinReg" function.
The first question referred to in the video is question 6 of the "Sinusoidal Data Exam Questions" booklet. It asks you to create a graph showing the depth of a tide over a time of 24 hours, as part "a". Part "b" asks for the period of the function, and it asks for what the period represents. Part "c", and the last part of this question asks for a time table showing when she has safe passage through the channel, knowing that her boat needs 1.3 meters of water to float.
Mr.Maks explains how to answer the question, and it's 3 parts in the video.
The second question he explains is question 11, which is about two Ferris wheels. It has three parts "a,b, and c"
Part "a" wants the max height of the first Ferris wheel. "b" wants to know how long it takes for the second Ferris wheel to complete one revolution. Part "c" says each ride costs $3.00, and both last about 5 minutes. Telling you this the question asks which ride you'd rather take, and why.
Mr.Maks didn't fully answer this question, that's is for tomorrow, maybe.
For the second approach for the first day of the exam, the first question he used for an example is question 17, which talks about a paddle-wheel. The question has three parts t it that asks:
"A" wants a graph to show the information.
"B" tells you to determine the equation for the sinusoidal curve.
And "c" asks for the length of time that the reflector is under the water, and it asks how you came to that answer.
(see video or look at the booklet to get the full question)

Today we talked about the exam and then we opened the June 06 exam and we looked at a question on page 14. We learned about net worth and he showed us a template previously made on excel that helps calculate the net worth of a person. Then mr. maks taught us about the 3 different types of assets. The three types are: Liquid, semi-liquid, and non-liquid. After we figured out Carmen's net worth we figured out her debt equity ratio. Apparently some people don't believe in the moon landing. Thats weird.

Study Schedule
Our blog projects are due TODAY!
We will get assignment marks for:
We are Encouraged to study for the Exam...By making a study schedule, and handing it in on Monday (this can also be a list).
There are 2 parts
1. An actual schedule that has dates and times (max 2h)
2. Block the content, what this means is are you going to organize your schedule by content, skill, study technique...IE: don't study stuff you know.
"Jump both feet right into the material you don't understand"
EX:"By this date i plan to have finished studying and understanding this unit
Exelerated Math is due by the 22nd.
.
We can also get old exams to practice on, just go ask Mr.Max for one!

Today, is May twenty eighth two thousand and nine. We are currently in block five, grade twelve applied math. Unfortunately, I need to leave at ten to three, and if anybody would like to add to my post feel free.. for I am sure to miss out on the wonderful mathematics that Mr Ryan Maksymchuk has taken the time to teach us. So sorry for the inconvienence.
I believe we are working on periodic functions.
We have been given a sample exam, with questions that similar to the ones we will see in a couple weeks.
Take the time to try some of these questions, it'll help prepare you.
on the video at the six minute mark... calculator instructions come out. so watch the video!
- 15 minute mark talks about how to take the dots from scatter plot data and change it into a function.SinReg, L1, L2, Y-1 (**how to get Y-1 Vars, Y-vars, wanting Y-1)
32 minute mark- tells you about how to graph it on Graphmatica

Test Day
Yesterday we jumped right into the test that everyone was dreading to write. Hopefully every one passed with flying colours.
Intro: Applications of Periodic Functions
Pre-Exam Tutoring - He will make available as much time as possible to help us after school and in the evenings. If we are going to come we should tell Max that we are coming so that we don't waste each others time.
We just got a copy of Jan 09 exam to study from. For exam we can use java applets, cheat sheet (formula sheet), excel, etc.
For periodic functions we can use either our calculator or Graphmatica. There is a video, so I won't go into detail this time. I may make little notes for you though.

* Listen at the 30min mark, eh.
