Comb. + Conics Test

First off, I apologize for not getting this post up sooner; the Sun computers were having some trouble with "Java enabled cookies" or something along those lines and I was consequently unable to log onto Blogspot.

At any rate, it should not matter as all that happened during my scribe day was the Comb. + Conics test, which I hope everyone performed well on.

Remember to get your Accelerated Math Objectives done on time (50 by next friday last time I checked).

C&P Test Tomorrow

Today's class was spent going over perm&comb questions before tommorrow's big test. (I can't figure out how to post the images from pdf onto Blogspot so if you want to see what Maksymchuk did just go to My Computer>Rsfiles on 'Svrss 2' (J:)>Coursework>Math>2nd Semester Pre-Calculus Grade 12 and then scroll down to find pc40april2308moreperms&combs.)

For more practice, feel free to do the math40s.com Permutations and Combinations exam (with solutions here).

Sincerely,

IB

Aloha, everyone. Today Mr. Max assigned Excercise #17, 1-12; and Excercise #18, 1-16. We get all of today's class to work on them and study for tomorrow's test.







He also told us that the test will be the same as the pre-test, but with different numbers. Since the whole pre-test idea seems to be liked by the whole class, we will continue to get pre-tests before each of our real bi-weekly tests.







One last thing-The latest due date for Accelerated Math is March 27th with 19 objectives.







Well good luck on the test tomorrow everyone!

Pi Day!!!

HAPPY PI DAY EVERYONE!!!

In case you weren't aware, it is also Albert Einstein's birthday. Also, a proper Pi Day celbration should not begin until it is 1:59:26 on March 14 (π = 3.1415926... = 3rd month, 14th day on 1:59:26).

Today's lecture was short as Mr. Maksymchuk decided that we should use the period to work on the pre-test and catch up with accelerated math. Employing the sum and difference identities that were taught to us yesterday, Maksymchuk showed us how to derive sleek-and-sexy numerical values for trigonmetric functions with"strange" angles, among other things:

Here he derived an equivalent expression for sec(θ-π/4):

Continuing with the sleek-and-sexy values:

And finally we were given our assignment:

Mr. Maksymchuk finished this around 12:30 p.m., giving us about 40 minutes to work on our pre-test and finish up our accelerated math.

Anyway, since this post was so short I think I will provide my fellow classmates with a puzzle they may or may not choose to figure out:

You have 9 balls - all of which are indistinguishable by sight - and a balance scale. Eight of the balls weigh exactly the same while the last one is either heavier or lighter than the other eight. This differential in weight is so small that you can not tell by holding the "odd" ball in your hand whether or not it weighs any differently than the other eight; that is, you will have to employ the balance scale to figure this out. What is the smallest amount of weighings that you can do to find the odd-ball-out? How did you carry these weighings out?

Feel free to post your solutions.

Math test day!!!

hey there, ...soo I was lucky enough to scribe on a test day....soo I don't really know what to say, but gonna try and find something interesting for you all to read...............



A Mathematician, a Biologist and a Physicist are sitting in a
street cafe watching people going in and coming out of the house on
the other side of the street.

First they see two people going into the house. Time passes.
After a while they notice three persons coming out of the house.

The Physicist: "The measurement wasn't accurate".

The Biologist's conclusion: "They have reproduced".

The Mathematician: "If now exactly 1 person enters the house then
it will be empty again."

(+2ppl-3ppl=-1 .....+1= 0 :D) ....just incase u were confused :P

The Exam

The setting is Ohio State University about six or seven years ago in a huge lecture hall (approximately

1000 students) for a Calculus final.

Apparently this particular calculus teacher wasn't very well liked. He was one of those guys who would stand at the front of the class and yell out how much time was remaining before the end of a test, a real charmer. Since he was so busy gallivanting around the room making sure that nobody cheated and that everyone was aware of how much time they had left before their failure on the test was complete, he had the
students stack the completed tests on the huge podium at the front of the room. This made for quite a mess, remember there were 1000 students in the class.

Anyway, during this particular final, one guy entered the test needing a decent grade to pass the class. His only problem with Calculus was that he did poorly when rushed, and this guy standing in the front of the room barking out how much time was left before the tests had to be handed in didn't help him at all. He figured he wanted to assure himself of a good grade, so he hardly flinched when the professor said "pencils down and submit your scantron sheets and work to piles at the front of the room".

Five minutes turned into ten, ten into twenty, twenty into forty ... almost an hour after the test was "officially over", our friend finally put down his pencil, gathered up his work, and headed to the front of the hall to submit his final. The whole time, the professor sat at the front of the room, strangely waiting for the student to complete his exam.

"What do you think you're doing?" the professor asked as the student stood in front of him about to put down his exam on one of the neatly stacked piles of exams (the professor had plenty of time to stack the mountain of papers while he waited) It was clear that the professor had waited only to give the student a hard time.

"Turning in my exam," retorted the student confidently. "I'm afraid I have some bad news for you," the professor gloated, "Your exam is an hour late. You've FAILED it and, consequently, I'll see you next term when you repeat my course."

The student smiled slyly and asked the professor "Do you know who I am?"

"What?" replied the professor gruffly, annoyed that the student showed no sign of emotion.

The student rephrased the question mockingly, "Do you know what my name is?"

"NO", snarled the professor.

The student looked the professor dead in the eyes and said slowly, "I didn't think so", as he lifted up one of the stacks half way, shoved his test neatly into the center of the stack, let the stack fall burying his test in the middle, turned around, and walked casually out of the huge lecture hall.

Have a great day everyone!
