Rene Decartes

Rene Decartes was lying in his room at the age of six when he noticed a fly above him. He realized that by using the indentations of his wooden ceiling, he could describe the location of the fly to his mother, (who was downstairs), without ever having to ask her to look at the fly. This method of describing things locations became known as the Cartesian Plane and is still used today as one of math's most fundamental ideas.

Computer Graphing Tool

Hey Guys,
Do you hate plotting points and drawing lines with a pencil? Is it a long boring process for you?
Well...
As I am continuing on my quest to find ways to doing certain tasks more effectively through technology, I stumbled upon a free graphing program that allows you to plot points. This program does not require you to have a degree in Nerdology; so you can do it. It does, however, require a bit of poking around the program. I have a good grasp on the foundations of this program, so if you have any questions pop me an e-mail.

All the best.

Scribe Post- Feb 4 (Cullen)

Hey everyone.

Today we only had a short class period because of the guest speaker. We started off class with a daily quiz on plotting lines. after we took the quiz, Jojo set the rest of the time aside to go over the last few nights of homework and any challenging problems.

For example, we went over problem 27 from our homework. it as a parabola, and we needed to find the domain and range. the problem was y= x(squared)-20. we know from plotting the parabola that the domain (the values of x)= (infinite, infinite). and since we know that the parabola will not go below the y-intersextion (which is -20) the range= [-20, infinite).

after we went over problems class was over. so YEAH!!! :D

tomorrow's scribe is christian.

Podcast Guidelines, Notes, & Ideas

FIRST PODCAST!
Lessons:  P2  -All, P3  -Omit (do not do) p. 24-26, P4  -Omit p. 32-33 
How to learn the information:
Read the lesson
Do practice problems -show all steps (homework- check on pbworks or back of the book)
Write out specific questions and submit (anonymously) to pb works question bank!
Ask questions in class
Watch videos
Listen to classmates podcasts or other public podcasts

How to create a great podcast:
Understand the information
Create Script first
Be creative in collecting slides (online or take photos)
Put it in garage band and make it fresh!


Be informative, be specific, give examples, be creative, have fun!

Scribe Post-Functions-Camila-February 3

HELLO,

Today the class focused on a few different things:

First we talked about the coordinate system and slope. Here are a few key points:

-If a curve has a slope then it's a straight line.

-Slope defines a straight line.

-Slope= rise/run.

-In any straight line the rise/run (slope) of any two points will have the same ratio

Then we concentrated on equations for a graph :

Slope intercept form: y=mx=b

Point slope: y-y+m(x1+x2)

Standard Form(the one we will be using): Ax+Bx=C

We then talked about how to find the x and y intercepts using the standard equation.

-To find the x-intercept substitute a zero for the y intercept

-To find the y-intercept substitute a zero for the x intercept

Here is an example problem

Find the x-intercept:

3x+5y=15

3x+5(0)=15

3x=15

3/3x=15/3

x=5 The x intercept is x. You can apply the same concept for finding the y-intercept

Scribe Post, Trigonometry, 2010!

Hey Everyone,

I hope everyone has started the term with a smooth transition so far! This term will be a very exciting term, concerning and regarding to our math class! We

will be focusing on a new math subject, Trigonometry. Trigonometry, stated from Wikipedia, " is a branch of mathematics that studies triangles, particularly right triangles. Trigonometry deals with relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those

relationships, as well as describing angles in general and the motion of wavessuch as sound and light waves." This new subject in class will involve making sure you have your supplies everyday at school. Supplies that you will need everyday include: a ruler, calculator, Trig. book, and your notebook, which includes your written homework assignments, and in class notes.

Although our previous scribe reminded us as a class with what we needed, its always nice to have another reminder. From what Jojo has stated, these new few weeks, will be a review for a lot of us. We will be looking at material that we have previous learned from previous years and even last term. However, just because it will be a review for most of us, doesn't mean "slacking off" and not taking the class serious is acceptable. Daily Quizzes will still be given out, homework will still be checked regularly and your assignments regarding the blog are still very important.

Now today in class, we all went to the computer lab and learned about a new way of presenting math lessons, POD-CAST'S.

In the lab we all got the opportunity to try out the program and make a few practice runs with even, fake scripts. Now pod-cast's are made from a program on Apple product computers. The program is called "GarageBand". We all learned that this program allows you to create voice overs, add pictures, videos, and even cool sound effects to your own personalized pod-cast. Jojo stated earlier that we will all have an opportunity to present a pod cast are more details are to follow. I think we all found this newly advanced technological program and exciting and interesting addition to our class. Can't wait to see what people come up with!

Today in class we had our 1st. Daily Quiz for the term! One important reason why doing your homework and reading and taking notes from your math notebook and the math book is because, may times, the daily quizzes are from homework and information from the book. For example the Daily Quiz today included two formulas from last nights homework and they are easily found in the math book.

Daily Quiz # 1. - Give the two formulas stated, "The Distance Formula and Midpoint Formula."

On Page 4 of our books, the Distance Formula is given:

On Page 5 of our books, the Midpoint Formula is given:

Today Jojo gave students who were unable to see the homework from last night on the page, because of technical interference, he let those students have another night to complete the homework.

Don't forget to do tonight's homework, (Pg. 11, 54-64 even, 66-72, even.)

I proudly announce the new scribe to wonderful and beautiful, Camila!

Have a great evening and I hope this post was helpful! Lets have a great term!
