This is my test question:
Solve for x: ln6+ln(x−2)=−2
(Express your answer correct to 3 decimal places.)

Here is the method I used to get the answer:

ln[6(x-6)]=-2
ln(6x-12)=-2
(e^-2)=6x-12
6x=(e^-2)+12
x=(e^-2)+12/6
x=2.022 556
x=2.023

Homework Ban!

In this class we were asked to read this article: http://tiny.cc/homeworkban it was about kids having too much homework. I can see some kids having a lot to do, but their solution to the problem is to not have anymore. I personally feel that this is not the best way to deal with the problem. To get better at anything you must practice it, yes there are people with natural talent but that can only take you so far. It's much like a sport, the players who have little talent can quickly become better than the naturally talented players by just working harder and with more practice. So I would say don't cut out all the homework, but don't take it as marks. There will be kids that take it all and do it all, and kids who do little to none. You will see how they progress and do on tests as a reflection of how much they do and their natural ability.

Probability!

Today we started probability. This is one of my favorite units! I can't wait to get this started. I really like it because it has always been very straight forward for me. You may think I'm joking, I'm not really. This will be a fun unit. Lets keep making outfits as well, just so Bobbie bear can go on vacation!

Excel Fun!

Today you told me to not fool around on my computer, it was also one of the days I really paid attention. You also reminded me to do my math, I will get on that just for you. I'm also very sorry I haven't posted in a while, I will keep on top of all this. Those were my Remembrance day resolutions.

Work Period

Today was a work period, I went over everything and I feel pretty confident about this test. My only problem maybe would be with graphing but I will just keep looking at that one. I also took a second or two today to look at the world cup qualifiers, France (my team) just has to beat Ireland twice they should be fine. Just thought I would let everyone reading know that.

Double Angle Identities

We learned about double angle identities today. They are the same as sum and difference really just an alternate formula. The only real problem with these I can think of is getting the question in the proper form. Other than that I really have no problems with it!

Alpha and Beta Formulas

We went over the alpha and beta formulas today, I found that they really help solving sine and cosine values. The only problem would be remember the signs.
