B0B

heyyah! this been a combination of hard stuff and fun stuff. The probability that I gonna failed this test is 70% but if I study....it would be 40% anyways my muddiest part is choose formula although I understand it more every time I apply this to solve the probability.well...may we have a nice day tom.

hello...this unit is not that hard although I don't really like graphing. Some key points did truly helps me in finding the right numbers to plug-in to the variable in which I've been able to make my own equation. I'm just worried about the test cuz I might forgot something like getting the focii which is my muddiest point...anyways..that's all...good luck to us...

BoB

I underestimate combinatorics, It's hard! My muddiest point are permutation,choose and cards...it's very hard to choose which one has to be the way to get the answer...

I really have to squeeze my mind....

I also have to use my widest imagination and put it on the sack and save it for tomorrow...pweh....
good luck everyone.....have fun(NO!)

combinatories and functional notation

Eow this is rosselle. I'm sorry for the late, late, late scribe....anyways...i'll start it with the afternoon class. Mr. K gives us the review for the test and he group us into 6 so here is it:


Domain:(2,infinity)
Range:(-infinity, infinity)
y-int: none
x-int: 7/3
aymp:2


domain:(-infinity,infinity)
range:(-infinity,1)
aymp:1
y-int:3/4
x-int:2

*ln is like a log. This is change of base law.

* We can't expand ln(x-1) and ln(x+3)any further since ln are not distributive!


*First I expand the lnx and lny using the product law and by quotient law, I divide lnz.

The class start with Mr. k's social commentaries. He talks about smoking and numbers from the lottery, I don't really get it cause I'm not listening... well anyways we are face with a new lesson and this is what we talked about for the mornin' class...




*There are 2 ways for n to be tossed. For every n1 and n2, there are 2 ways that q1 and q2 to be tossed and so that would be 4.
And for every q, there are 2 ways that d1 and d2 to be tossed and so that would be 8.
Now multiply all the numbers :2x2x2=8

*The difference between the Combinatories and Modeling is that combinatories shows how many ways that can be done and arrange items, the following examples show how to use it.

*There are 3 ways to wear the P1, P2, P3 then there are P1 x P2 x P3 ways to do three things.




*There are 5 people that can be seated in this straight line.
*we used up one number, so we have 4 people to be seated.
*3 people are remaining
*2people remaining
*1person remaining

Sorry for the inconvenience in reading my scribe...i know it's blurry....now i can sleep...next scribe is michelle.....thank u thank u...ajah ajah...

Log-a-rithms BoB

First of all, every time that Mr. k says that the logarithm is an exponent it makes me really confused, but honestly I beginning to like it, it's hard and complicated but it's fun especially the laws. Because I've been able to manipulate the logs to make it more simple. But I'm a little confused about solving for x and all that stuff. I don't know where to start but I've been working on it. I don't get the exponential modeling, I really need to work on that stuff......oh men... i forgot... I don't like "ln"......wish me luck.....

Honestly, it's hard for me to create an equation, for example create a cosine equation, create a sine equation because I don't know what the exact number should be use to get the correct answer. I get confused easly, but I know how to place them and to identify them. Another thing that bothers me is graphing. I know what to do but when the time comes that you have to graph it, I get totally lost!BOOM! Good thing i love to draw.. anyways....Transformation and inverse function is tricky.. but I found the lesson interesting and that keeps me on going.

This is rosselle by the way.. I used Jordan's account because i forgot mine...

hi!Unfortunatley Mr. K is absent for today so we're just asked to answer exercise 4.... that's all... and be ready for a mental math tomorrow....c yah ^-^
