Factorial Notation

Permulation- an ordering of objects in which ORDER MATTERS
ex. phone number, locker permulation, postal code, etc..

Combination- an ordering of objects in which ORDER DOESN'T MATTER
ex. card hands, pizza topping, etc..

Today, we learnt what these words are and how to solve a problem. There are a few ways so check out the notes. We did not do mental math today either.

Fundamental Counting Principle

Today we learned about Fundamental Counting Principles.
A.K.A F.C.P (&Factorial Notation)

"...if you can do event A in a ways, and event B in b ways, and event C in c ways, etc.etc.... is.....

#of ways to do A,B,C =axbxc...

We also did mental math today and were assigned some accelerated math to do as well. SOOOO our homework involves finishing our vector projects, exercise 4 from the vectors book, all of exercise 2 from the counting principle booklet we just got, and accelerated math. That's a lot of homework especially because i'm not going to be here tomorrow or friday.

vector project

Today i started the vector project. My idea is to have a "stage" and dancers on it, the choreography requires one dancer to move from the south east side of the stage to the north west side of the stage. I have to find five different ways to get there moving through the other dancers spots. This should be fun.

parallelogram method exercise 3

i worked on exercise 3 today and got lots of help so i understand it really well now. I feel confident enough now to go on to exercise 4 which is supposedly a lot harder. I haven't started working on the big project yet i still don't understand it to the fullest.

vectors

No mental math today we just went straight into our homework. Mr.maks asked us if we wanted him to show us any questions so he did question three which actually seemed very easy after he explained it. I think i like this unit. He showed us in question three that it didn't matter where the hurricane was just as long as it was going 45 degrees north west and the first one is 3cm and the second is 4 cm. 1cm=10kph. Also a resultant vector is the distance from the end of one point to the end of the other when the two are added together

Today is early dismissal. So everyone should have lots of time to do their homework which is all of exercise 1 and 2.

vectors

We are starting the Vectors unit. To solve these problems we can use Euklid or you can use the cosine laws and trigonometry rules. Euklid can be downloaded at home too.

VECTOR: anything with both magnitude and direction. How much? And which way?
SCALAR:representable by position on a scale or line; having only magnitude
MAGNITUDE:size; extent; dimensions

REMINDER: Bring graph paper, ruler, and protractor

There are three methods:
1. degree? direction? of direction?
2.start direction? degrees? which way direction?
3. measures <360 angles using N=0, and clockwise so bearing is 340

Exercise 1 and 2 is for homework in our booklets
