Mother BOB

First of all I would just like to say Happy Mothers Day to all the people who are like a mother to someone. The world needs to be nurtured by someone.

Anyway this is the END of the CONICS section.
It felt like the unit went by fast. I enjoyed the paper folding.

The unit consisted of parabolas, circles, hyperbolas and ellipses; which was pretty straight forward to understand.
The only thing is some of the problems towards the end were a little more difficult, other than that OK.

MR. Siwwy, good post.

GOOD luck you guys on our test later on.

The Scribe That Almost Wasn't

Hey guys this is Mel and I'm so deeply sorry that this is late. This is what I get for being such a novice with computers and trying to make the scribe look fancy. I learned my lesson K.I.S.S. and people will still learn as long as all the material is there.


MONDAY, after Mr. K was finished preparing the days lesson we got right to work.



He hit us with a question:



a) How many ways can the ways GEOMETRY be arranged so that vowels and consonants alternate?First we give 8 available spaces labeled cvcvcvcv because the vowels an consonants alternate.

YES, in this case Y is a vowel !!!!!!!!!!!!!!!!!!!!!!!!!!!



There are four vowels and consonants so in the first space there are 4 available consonants, in the second there are 3 in the third there are 2 and in the last space there is only 1 consonant available so therefore is labeled one. Same pattern applies to the vowels.



In the above illustration there are two sets because you could either start with a vowel or start with a consonant.





Then you mulitply:

Note: you add 576 two times because there are two sets.







b) How many ways is y the last letter?



Quest. 2

How many ways can student council choose a subcommittee of 5 people from the entire council which consist of 11 people?


Comination: An arrangement of objects where order does not matter.


Given a set of n objects, how many different groupls of n objects can be chosen were order doesn't matter.

For example:



How many different tickets can be sold in the 6/49?

(Basically just plug in the numbers)

To punch this in your calculator

Press the MATH button

Choose the PRB

Choose the third choice which is n choose r

In other words, you much better off just saving your money!!!!!!!

I'm still in the learning process for these blogs, as you can tell I'm not that great, but i hope i covered everything. Until my next duty this is got MELk out.

Playing with Trigonometry

The end of a unit has come again.
One of the significant things I need to point out in this unit was I really really needed to practice.
YOU CAN'T MEMORIZE THE SOLUTIONS, but just derive them. I think another downfall of mine is when you try to remember all the solutions in a short amount of time and then you mix them up when your put under pressure. Ha ha yes, I shall be a prime example of that.

The sine dance, I admit that the dance doesn't really help (sorry for all your effort Mr. K) but the rhythm has definitely stuck in my head.

Am I ready for this test? Well, just a little more practice and it might be all right.

Good luck to all of you....practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice practice
that makes it perfect....

Until the next BOB.

Pi it's history, it's present, it's the future, it's in my belly!

Pie was the yearning in our stomachs as we all walked into class pondering what kind of pie the others have brought.

For my blog I will give a couple of facts about pi. I was going to discribe the assignment, but thankfully Mr. K was 3.14 steps ahead of me. (ha ha)

->This is my graph about about how good all the pies were this morning. As you can see by the data they were all CRAZY GOOD PIEs (x-axis) and as a result TASTE BUDS WERE OUT OF THIS WORLD (y-axis). In other words I'm just trying to say that today was great. Even though I didn't taste all the pies, I could tell by all the groaning that everyone was satisfied! The red is a power curve and as it's value goes up, the size of my belly also goes up!!! hehe

First of all I would like to say HAPPY BIRTHDAY TO ALBERT EINSTEIN!!

Pi Day and Pi Approximation Day are two unofficial holidays. They are held to celebrate Pi (π) a mathematical constant. Pi day is celebrated on March 14 (3.14) (Sometimes it is celebrated on March 14 at 1:59:26 p.m. actually known as the pi minute because pi is rounded out to seven decimal places.) Pi Approximation Day may be observed on any of several dates, most often July 22 (22/7). I actually tried to read about the result that the rational number 22⁄7 is greater than π, but I sort have a few holes I need to fill. (Hey Mr. K, if your reading this could you explain that?)

As everyone was chomping on pie, Mr. K was explaining our assignments.

From what I understand is that for the photo assignment we need to take a picture of something that occurs NATURALLY in nature. (Not something we made up.) This picture needs to be about trigonometry.

Developing expert voices, I believe is an assignment that we have to be true to ourselves to accomplish. We need to realize our strengths and set the bar up higher and jump higher to get over that bar; we need to challenge ourselves. We need to push ourselves out of our comfort zones so we can really learn and discover what math is means to us. (I guess)

Other dates for us math people to celebrate!

March 14: A common approximation for Pi (3.14)
February 27: The Earth is estimated to have traveled 1 radian of its orbit since the New Year
July 22: 22/7 in the majority of date formats, an ancient approximation of pi
November 10: The 314th day of the year (in leap years, November 9)
December 21, 1:13 p.m.: The 355th day of the year (in leap years, December 20), celebrated at 1:13 for the Chinese approximation 355/113

That is the end of my first SCRIBE ever!!! I hope I was up to our class standards.

BOB the BUILDER

I believe that everything that we learn in life is taught in chapters, and sooner or later we need to take all those chapters and make a conclusion. This is what the unit TRANSFORMATIONS felt like. It felt like I needed to go back try to remember how to graph and do questions regarding transformation.

Again "stretches before translations" stuck in my head.
DABC made an appearance in our unit again. I learned that:

D- Shifts graph LEFT to RIGHT
A- STRETCH OR COMPRESSION on Y coordinate
B- STRETCH OR COMPRESSION on X coordinate
C- *WATCH THE SIGN* shifts graph LEFT OR RIGHT

I was happy when I finally understood the difference between a inverse functions and reciprocal functions. I just need to remember that it is an INVERSE is when you switch the x and y coordinates. Reciprocal functions however comes with the invariant point (always -1 and 1), then the roots (for the asymptotes) then the biggering and the smallering.

As for the odd and even functions I get that the odd functions are symmetrical over the origin, and even functions are symmetrical over the y-axis. The only thing that's making me feel a little restless is the equation part of it. (like how when and where you subsitute things)

Other than that this unit was OK. Not great, not bad just mediocre.
Good luck on the test!!



The picture below is me pushing the rock, Mr. K behind me helping and behind him is the class. This just goes to show, no one person can defeat the mountain alone. Thanks guys.

BOBin' for apples?

This is the first time I've been in a math class were I had to blog before a test. I think this method is unique because instead of reflecting on how much you've done over the semester your doing it in regular intervals. By doing it this way as a student, we see how much we grew, and the problems we need to solve for the next unit.

Something that made me happy about this unit, circular functions, was that when math gets tough, make it simple. Let me explain, if you can count 1, 2, 3, and sometimes 4 then you can certainly learn about the unit circle. That was such a relief. heww. Sometimes I still can't over the fact that I get math (and sometimes I even enjoy it).

Something that I would like to do is study with people that I don't really know from class. I find that it's true, that when I study with people (in my math class) that I don't know, there's a less chance that I will get off topic and start talking about the 'latest news'.

To my precal 40s class, good luck to you all!
