Today is another work class! There is only nine days until the exam, not including today, but including the weekend. There is only seven SCHOOL days until the exam, yikes! Make good use of your time guys, if you did make a study schedule, follow up with it! It'll help tons with time management. Make sure you cover all the topics, and ask questions when you need! Whether is be asked at Mr. Maks, or one of your peers, anyone will help. I'd also suggest you use that coil bound book we checked out from the resource centre at the beginning of the year. I've found it super helpful throughout the semester. Happy studies!!

Just think, THIS is what we can look forward to!!

You CAN teach an old dog new tricks!!

DID YOU KNOW THAT?!

If you add the numbers of the numerator and the sum is divisible by three, and then you and the numbers of the denominator and the sum is divisible by three, the fraction can be reduced! For example...



2+7 = 9
1+7+2+8 = 18

9 and 18 are both divisible by three, therefore, this fraction can be reduced.

=

NOW YOU KNOW!!!

But in case you still don't get it, it's okay because...

Conics, Again!

Today we are talking about hyperbolas specifically, as compared to yesterday's class when ellipse's were discussed.

Here are the note slides from the class!





I don't know about you guys, I actually find this Conics unit to be one of the simpler units we have done thus far in this class. I like it because it is strictly formula based and pretty much just plugging in numbers.

I found this site to be fairly useful as well, check it out if you have the chance!
Hyperbolas

The assignment today is Exercise 38, questions 1-10

Probability!

Today we did probability in class. Personally, I don't understand much of this at all, hopefully these notes help out!










The assignment is Exercise 28: #1-9 for new stuff, and #13-17 as review.

P.s. 5! is 5 factorial, not FIVE!!!!

... Housing?

Today we started off class with a discussion about technologies and how it's been affecting our lives. A few questions were posed... is it taking over true social interactions? Will we ever resort back to our roots and leave technology behind? Personally, I really couldn't tell you what will happen. I would hope, though, that we would find a healthy balance between both. I think technology has it's place in society, and that it is a good thing that we have had so much improvement in the last little while. I feel it's kind of like dark chocolate or red wine... it's good for you in moderation, but with over use, things could get out of hand...

Back to Math!

We started on Natural Logs and Equation Solving today. Here are the slides...

Wait... turns out, we ended just looking at houses and how ridiculously priced they are. Interest rates right now are actually crazy low, so if you have the money, buy a house! But none the less, even WITH the low interest rates, mortgages still seem to suck a whole lot. I'm not sure if I'm looking forward to that section of my life...

We looked at some intense house prices today. Scared me a wee bit actually. A half decent house in a city is a ridiculous amount of money, and even prices here in the valley are on an incline. So everyone, invest your money wisely, because if you wind up purchasing a house (or an apartment such as the 1.5 million dollar one in BC), you're going to need the cash.

Here's a couple options... you choose.

Ew! Red Meat!!

Well, today in class was an open day. We all worked on exercises or accelerated math that had been assigned. We're trying to prepare that I heard Mr. Maks call the "Man-maker" test today. I wonder if I pass if I will start to grow chest hair? Anyways, this article I found very interesting, especially since I'm not a huge fan of red meat at all. I stay away from it as much as possible. People always think I'm silly, and tease me and what not, but you know what? Now I have a valid excuse... "I'm silly? Really? Because I'm going to be living longer than you, you carnivore!" Haha. Totally kidding, but I do find this article very intriguing, check it out!!

Red Meat Consumption linked to Cancer, Cardiovascular Disease

Monday, April 13th, 2009

Dr. Richard Beliveau

Once considered a delicacy reserved for special occasions, red meat has become a regular part of our diets -- and not always to our benefit.

Those who eat more red meat have a modestly increased risk of death from all causes, cancer or heart disease, according a recent study by the U.S. National Cancer Institute.

The survey -- the largest done to date on the impact of red meat on health -- looked at more than half a million people aged 50 to 71 over a 10-year period. The results were released in the March 23 edition of the Archives of Internal Medicine.

For years it has been known people who consume large quantities of red meat have an increased risk of contracting certain diseases, particularly colon cancer. This is caused by three main factors:

1) Grilled meat that has been charred on a barbecue contains carcinogens that can cause the genetic mutation of cells in the colon, which can develop into tumours.

2) Red meat is an important source heme iron, a type of iron linked to the myoglobin in muscle tissue. In high doses, as is the case with frequent meat eaters, this type of iron can irritate the colon's mucous membrane and cause abnormal cell growth which can lead to cancer.

3) Frequent red meat eaters often have a poor diet of fruits and vegetables, food items that play a crucial role in protecting the body from cancer.

In the study, researchers scrutinized the eating habits of more than 545,000 people beginning in 1995.

The participants completed a food frequency questionnaire to estimate their intake of various meats and were then followed until 2005.

During that period, 47,976 men and 23,276 women died.

The researchers found that people who consumed more red meat, about the equivalent of a quarter-pound (115 g) per day, had a 22% greater risk of dying prematurely from cancer and a 27% greater risk of death related to a heart ailment compared to those who ate less than a quarter-pound of red meat per week.

The correlation between red meat and cardiovascular disease seemed more prominent amongst women, with frequent meat eaters having a 50% greater risk of dying from a heart-related problem compared to women who rarely ate meat. Interestingly, these negative effects were not observed with white meat such as poultry and fish; those who ate these types of meat actually had a reduced risk (15-20%) of dying from cancer or cardiovascular disease.

It's important to keep in mind these observations do not mean red meat should be completely cut out of diets.

The delicious taste of these meats has been used for millenniums to add taste to soups and gravies as well as to dishes such as couscous, stews and different types of Asian stir-fries. It would be a shame to have to give it up completely.

Still, the recommendations of the World Cancer Research Fund are to reduce our intake of red meat to 500 g per week and to add other sources of protein such as fish and legumes to diversify our diets and improve our health.

Welcome Back!

In today's lesson we learned more about logs! WHOOP!! Hope everyone had a great spring break, if you're like me it feels like it went too fast. Just think of it this way, there's only... 52 days left of classes (and counting)! Take that as you may, but I'm pumped. That means 52 days until a two MONTH spring break, aka summer holidays.

ANYhow... this is the notes from today's class...















And the video...




The test is now post-poned until next Wednesday, April the 15th. And we can still rewrite the test that we all did poorly on earlier. Perhaps next week? Let me know, if you have any suggestions, please comment on this post! I'll be checking!!

Mr. Maks strongly suggested that we remember to look and learn from our workbook as well! The R.J. Mickelson one. I know that I love it. I wasn't using it, and I was doing poorly on my tests. I read through the units we had covered, tried a couple of their example questions, and I got FIFTY PERCENT HIGHER on my next test! Now, obviously I had a lot of "learning room" you could say to get that big of an improvement.... but the moral of the story is, if you take the time to read the stuff, it will benefit you!

Happy Readings!











The assignment for this evening is Exercise 22 questions 1-14. And if you do your questions like Peter, I'm not sure Mr. Maks will be too impressed. Good luck!

TRIG CHEAT SHEET!

Wow! As I was preparing for tomorrow's test, I found this amazing 'cheat sheet.' Really it's just a bunch of formulas, but only for trig. I still find it amazing because it includes virtually everything! I'd check it out if I were you! Print yourself a copy, I know I will.

Trigonometry 'Cheat Sheet'

Transformations

Hey Guys! Today we learned about Transformations, a new unit! It's all about functions and what not. Here are the notes! I'll hopefully be adding more info tonight when I have a minute. Until then, this is just the plain and simple version; cut and dry persay.

Here's a ridiculous math joke to entertain yourself with...

Q: What do you get if you divide the circumference of a jack-o-lantern by its diameter?
A: Pumpkin Pi!

Hope you enjoyed it as much as I did (which was quite a lot).

The homework is Exercise 7 questions 1-18. Good luck!

Trigonometric Ratios

If you ever come across a question like this, don't worry about the technology! It could make things much more complicated than necessary, unless you're good at changing about a million decimal places into whole pi units. ;) Refer to your unit circle, it will present things in a much neater manner.

See, this right here is what I'm talking about. 30 degrees is equal to .5235987756 OR pi over six.

How do they relate? Well, they're equal to the same thing, 1/2.

If you are wondering why we stopped at just these four numbers, recall that we had a statement before saying... Zero is less than/equal to thata which is less than or equal to two pi. (Sorry I have to put it into words, I couldn't find how to use symbols on here!).


This has the same idea as the above example, remember to stay within the limits of the equation given.

I'm going to be completely honest with you guys, this slide didn't make much sense to me. I don't understand what on the graphmatica graph applies to what/which things he wrote. If anyone else understands, it would be great if you left a comment explaining it for us (or me at least)!

This slide basically explains that if a function is inverse, it will like like a "mirror image," persay on the vertical line y=x. It's a great test to see if the answer you came up with is correct.




The range is restricted to only quadrants one and four because of the equation we must follow (-90 degrees is less than/equal to "y" which is less than or equal to +90 degrees).

At this point, I'd say it's almost vital to have your unit circle close to memorized, or at least to be able to visualize it when doing problems such as these. The link posted below leads you to a site in which you can slowly learn/memorize the circle. It kind of works by process of elimination. You can even quiz yourself afterwords. I hope it helps you!

Remember the Unit Circle

Here is one small tid bit of information for you... Many of you may of heard my excitement in class about the "pretty calculator"; I really am quite excited for it. I tried a few functions with it too, and it runs fairly smoothly! Hope it's of use to you.

Enjoy watching basketball tomorrow!
