Radians and Degrees

Good for the test tomorrow

I just thought this would be a great reminder to post before the test tomorrow
How the graphs look when dealing with the different Y equaled to X

Y=X squared The graph will be a parabola
Y=X The graph will be a line
Y= lXl The graph will be a V shape (But pay attention less than or greater than zero)
Y= the root of X The graph will look like a turn signal
Y=X cubed The graph will be one very curvy shape (both negative and positive)
Y=1/X The graph will have a two shapes that look like the letter C's that they were crushed on the X axis. One is negative while the other is positive.

Problems with podcasts.

I think these could be problems everyone is having, so I'll just ask them here. I can't open FLTTE p.3 podcast, it says the files are in the wrong format. Also is there a way to check which critique forms I've sent in? Also some of the files sent to us did not have their group name, so I had to guess which group had made it, is there a way to fix that?

Friday, February 12, 2010 scribe post. Jordan

Today in class Jojo spent most of the time preparing us for our section P test on Tuesday. we started off getting into groups to discuss the chapter and go over what we did not understand for about 15 mins. We wrote questions and circled the problems that we did not get correct. After that we, as a class, asked and went over all the questions that we did not understand. Jojo focused on section P.4 #49 which was f(x)=x^2-4 for x is greater than 0.

He also went over all of the parent functions that we will need to know for the test. which are... y=x^2 ,y=x, y=|x|,y=√x, y=x^3, y=1/3. thats about it. guys study study study. enjoy the snow and remember to label your axis!!

next scribe is Mon

Housekeeping...

Classes,

We have not had a scribe post in the last few days because one of our scribes never posted nor bothered to name a new scribe.  There will be consequences for everyone, if someone doesn't step up and become the scribe tomorrow.

I have not posted the podcasts or the critique forms yet, due to technical difficulties of many of the groups.  I will have something posted as soon as I sort things out for everyone.  Tomorrow we will use class time to review some of the concepts you have been working on for homework.  I will also return your homework assignments for you to review over the weekend!

See you tomorrow,

Teacher

Types of Symmetry Leading to Groups

http://www.learner.org/courses/mathilluminated/units/6/textbook/02.php

I found this website on symmetry today and I thought that others in our class may appreciate it. I’ve looked it over and it all seems to be pretty legit, also it comes from a credible source: learner.org.

This site does a nice job of explaining symmetry, giving us examples of symmetry, and relating it back to topics which we have already learned such as equilateral triangles and circles. Maybe it’ll help since you will have a better point of reference for understanding the new material.
