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 -__-'
