The nicotine portion of the project needs a re-do for everyone that handed it in. I have clarified the questions and willl be posting those soon. If you have an INC for this project, you have handed it in, but it needs work.
clarified questions

special Christmas News
I have marked the vector test and posted marks to EDLINE. As a special Christmas present, I am allowing a rewrite of this test. To qualify , students must achieve 100% on the quiz that I have created on EDLINE. It will appear on the calendar every day until Jan 4th and on the right under CONTENTS. You may take the quiz as many times as you want but you must get 100% before Jan 4th. You must also attend a lunch session to correct your test on Jan. 4th at 12:05. The rewrite will happen on Wednesday Jan 6th at 12:05. You MUST write it at that time. Some people have not opted for email messages so spread the word. Try to talk to at least 1 other person in the class.

Adding Vectors
Today is December 10, 2009. It is a chilly -22 Celsius tonight in Dauphin Manitoba. Earlier in the day we learnt how to add vectors, quite simply an easy task to accomplish. We learnt the "tip-to-tail" method and we had a brief discussion about parrelogram vectors. Attached is basically what happened in the class:
I cant copy an example of what we did on to here because it's not working for me, it is straight ridiculous. This is extremely rattling because i cant even add a picture either now. So im giving up on this blog and going to watch letterman. Do numbers 1-4 on page 318 for practice and Tommorow we learn Equilibrant vectors.

DEC 7 tut 7-1 vectors
yay the maths version of physics, fun class. anyways basic from what i remember from my time in physics is there is two kinds of vectors:
vector: has direction
scalar:has no direction
basically ; if the qestion says u are going 130km/h and does say anything about goes east west etc the it is a scalar
if the qestion say u are going 130 km/h at a direction heading west then it is a vector
so the line is the magnitude or the total distance, what ever the question is asking. the line must have an arrow head put on it or you will lose marks
NORTH SOUTH EAST WEST, north always is on the top unless told other wise.
there is also another meathod finding direction called bearing and north is 0, east is 090 south is 180, and west is 270. bearing is like a compass but it uses numbers instead of using names.
yay more physis terms
Displacement: how far in what direction; km miles etc
Velocity:how fast in what direction; km/h miles/h
force;how much force in what direction; N or called newtons
scale must a very important thing, should always always be cm = whatever it is
assignment is page 308 3ab, 4cf, 5

DEC 3 tut 6-4
again i missed another post lol, anyways to days we learned about the KOCH SNOWFLAKE yay. we learned a bit more today on how the fractorial thingy ma jiggy works. we worked on the snowflake and filled in tables on the perimeter & on the area.
the perimeter we found the sequences on the # of new sides and the lenght of them, then to find the total area you could have taken "new side x new length" to get the total length. another way to do it is take the "previous total perimeter x {length/side}" and you will find the next total perimeter.
mr bennet also have premade graphs showing us what they would look like when we plugged the values into excel and made a graph.
to find the total area it is the same principle put in the values and find the sequences, get the total area
we also did the Sierpinski Gasket which had the same principle.
i guess a key note is that perimeter graphs increase but area graphs level off over a period of time

DEC 2 class
on dec 2 we had an intro into fractals, it was a very productive class. first we learned the basic principle behind fractals. which is no matter how small it gets it still looks the same so a person could keep on zooming in the pic and it would still have the same look to it. but it also works in the opposite direction also. if you zoom out it will also have the same shape and look to it........
after cutting out a box style fractal we learned a little about the math. as a class we filled out a little chart that showed us how over time the perimiter increases but the area after a few time starts to make no difference in the total area of the fractal
Page number on the text with a little more info is: #276 or tut 6-3
hope it help

Sequences
Today we received a hand out and talked about sequences. We went over the whole sheet that consisted of two medium sized questions. The basic settings you should know for this unit and what Mr. Bennet would like to see on YOUR cheat sheet is shown below.
Window settings: (example)
Min: 01 =# of terms
Max: 50 = "
plot: 1 = ( Ignore )
plot step: 1
Xmin: 01 =same as above # of terms
Xmax: 50 = "
Xscl: 01 -----> ALWAYS 1
Ymin: =actual values in the sequence
Ymax: = "
An example of one of the questions that we did together in class is shown below.
2. Jasmine broke her collarbone in a bicycle accident. Her doctor's prescription contains the following information:
Each pill contains 240mg of medicine
Jasmine must take two pills every 12 hours. This represents one dose.
She must take all 32 Pills as prescribed.
A) If Her kidneys eliminate 60% of the medication from her body every 12 hour. How much of the medication is in Jasmine's system immediately after she takes the 6th dose?
Calcuator buttons: [2nd] [Y=]
min= 1
u(n)= u(n-1) *.40+480
u(nmin)= {240}
Calcuator buttons: [2nd][tblset][6]. [[2nd][graph]
6= 796.72
B) sketch a graph for 16 doses.
Calcuator buttons: [Graph] ( you may have to change your window settings)
C) At what level does the mediation stabilize?
(to find this answer open your graph and arrow down until your u(n) stays the same number as the one before it.)
14 doses=800 stabilization number
d) Assuming that Jasmine take all her medication. How many hours would it take for her kidneys to eliminate the medication after her last dose? ( when its below 1mg its considered eliminated)
to solve you take 8*12=46 hours
e)Jasmine visits a second doctor for a different opinion before she starts the medication he informs her that the stabilization must be between 1000mg and 1200mg to eliminate the pain. describe the schedule for taking the medication if the pill that Jasmine is prescribed contains 240mg of medication and her kidneys eliminate 60% of the medication every 12 hours.
( you would solve this question the same as you would solve the first part except change a few numbers)
The answer is it would take three pills.
We also received two questions for homework that we will go over together in class tomorrow.
