jan. 9 2009's class..
On today's class we started the discussion talking about intercepts. We kinda went back to our last year's topic. Then Mr. K gave us a few graph that we could solve. The examples are on the slides. We started the workshop it went great. At first we don't really get it but when me and my group started talking about it I knew it wasn't that bad. Yaseen was pretty tired explaining what he did because he did it like three times. The most confusing part of the discussion was solving the pattern then you need to sketch it in the graph then define if its a function. Jess and Yaseen had a little debate about the equation. They were talking about what is the answer in the equation. It is confusing at first and but the longer we talked about it was ok. We kinda started the making a library or something. But it was something about library. We solved a few number pattern. It was easy. But I'm expecting that it would be hard the moment we came to the point where we should study harder or bigger numbers. Mr. K also told us to study for the exam.
And our assignment is ex. 58..
the next scribe will be AKEEM??

I'm not sure if Ana will be able to blog so in case she's cant, I will do it for the Friday's class.
On Friday, we only got through three slides. But aside from that, the class ended up pretty better than the other dry days; like what Captain Oh Captain had said.
In the beginning of the class, we had a hard time before getting to actual math because of the Blogging thing. Apparently, no one has blogged for the last few weeks meaning us students are actually losing easy marks just by not blogging.
Anyway, we also talked about groups. when Mr. K puts us into groups, he's telling us to work with each member of the group on solving the questions/equations. Or in other cases, sharing how we got to our answer because we cant learn just by watching someone else do it. Mr. K used basketball for example. If we just watched a basketball player shooting hoops, would we actually be able to do it? Of course not. Unless you do have the ability to have that kind of power. But anyway, the point is that we actually have to try it ourselves to get better at it. Mr. K also used a video game example. Most of us had played video games right? Well why don't we treat pre-cal and any other subject like a video game? When we play for the first time, do we actually get to 1st place? No. But it's not like we gave up that easily; WE KEPT TRYING.
Well I'll be talking about the work now. Today was pretty much just a review. As you can see on the slide below, there was this question that said " What is the domain and range of each relation?". For a) D : [ 0, 6] , R : [ 0, 6] The 6 was figured out because the center of the circle was 3. So it's like giving us a radius right there. 3 multiplied by 2 is equal to 6. And the 0 was figured out because it touched the x and y axis. Or well, from my point of view, I think that's how it worked. for b) , c) , and d) are still a little scrambled in my head so I apologize for not being able to explain it.
By the end of the class, we learned about Intercepts. Like when we want to find a y-intercept, we have to LET X = 0. And vice versa for the x-intercept.
HOMEWORK : EXERCISE 57.
NEXT SCRIBE : ANA??
PS: I hope I dont get in trouble by scribing -__-'
