Once again, it’s been days since I’ve gotten access to the blog. But I still manage to get things done. Conics—the in-depth look at the aspects of a cone. It sounds like I’m writing a feature article on it or something. I sort of enjoyed this unit, it had its moments. It was pretty reminiscent of the days when I was master paper folder in origami club. By the end of emphasizing each shape that evolved from a cone, I simply wondered, “what happened to just making cranes?” I also commend Mr. K for his innovative [yet deadly] ways of disarticulating a cone with a shward.
This may have been a short unit but I really have to admit that I learned a lot. I didn’t know that so many shapes could come from a cone, or two cones to be precise. A “hypercone”, just kidding… The proper term of course would be the double-napped cone that gives way to a hyperbola, a parabola on steroids. Sarcasm, my native tongue.
The class learned each of the formulas and also learned how to graph the formulas. Call me juvenile, but I still have trouble with the grade 12 version of the parabola. I think the 4p always throws me off. I also feel like using the other formula from grade 11 though. But using that idea again should be avoided since thinking would not be lateral. This is why practice makes perfect. I just need to do a little adapting. Otherwise, I’d think I’m ready for the test today. Just keep my hocus pocus my focus, look it’s a locus.

BOB: Conics
WOAAAHH!! I almost forgot to do my BOB again! Sorry this is really really late XD
Okay, this unit was one of my favorite units. I actually enjoyed graphing for this unit and I thought that the concepts were very simple. It was a good break from the Counting unit, which I didn't really like much. I also enjoyed doing all that folding during class, such easy homework! This unit was also full of laughs, we really couldn't seem to stay serious most of the time. As for the parts that I found the hardest for this unit, I would probably have to say that the hyperbola and ellipse were definitely the most difficult, although not by much. I got confused at first with how to find the foci and the asymptotes (hyperbola) but then it all made sense after some explaining. I also remember messing up graphing my vertical hyperbolas since I switched around the transverse and conjugate axis. All in all, tis was a good unit, now I got to get ready for school! Good luck on the test guys :P

BOB on Conics
Hi guys this is Richard and here is my bob on the unit of conics.
This unit was not as hard as the other units there were some parts that i got really easy like the ellipse. I probably found that this topic was easiest because i had to scribe for it or it is just the simpler out of the conic shapes. Another thing that was cool was that we got to do a lot of fun folding. That led to the geometry of the conic shapes.
There were also topics that i found difficult for example the parabola. I think that the main reason i don't understand it is because i was not present for that Pre cal class. I almost forgot that the graphing of the parabola is also hard. i also felt the same was that Francis felt on that Pre test. I was also puzzled by the transforming parabola question . Well that's just me ah ha

Conics Bob
Ahhh Conics. Too bad Mr.K didn't show us any more of his samurai skills with this metre-stick-katana.
To the point. I will admit, like every section in this course, I had troubles in one way or another. The origami was cool, as it went with the whole Japanese theme Mr.K was trying to capture (TOYOTA-HONDA-MITSUBISHI-MAZDA-YOKOHAMA-SONY-etc...) Like every other type of graphing, I don't like to graph. Granted it does give me a better look at whats happening and I can tell what's happening, but like everything else in life, just because you know how to do it doesn't mean you're supposed to like it. Like graphing.
I liked how parabolas, circles, ellipses and hyperbolas had their distinct way to tell each other apart without having to think hard but rather just look at what's switching to make it graph that way. But, that's probably about it. The math was pretty simple once I took the time to sit down and study it all, like I am tonight.
I didn't like word problems however, how they make it seem like it's supposed to be something it's not, but yeah, I know, I'm just over complicating it.
I will be deep in study for a while because well, exams are closing in surprisingly fast. OH and don't forget about your DEV projects.

BOB on Conics
This unit was quite short, but I'm not celebrating. Personally, I need a bit more time with this unit, only because I don't think we went far enough with transformations that can happen with each conic shape. On the pre-test I saw that one question where the graph of a hyperbola was stretched 4 units, and moved down 1 unit, I was sitting there staring at the page for like 5 minutes, forgot all about those transformations. Plus, I don't think I can remember all those equations such as the equation of a circle, ellipse, hyperbola and the new parabola equation. Hopefully we'll get a formula sheet, or some other type of aid. On top of that, I don't fully understand the total anatomy of all these conic shapes, such as the major, minor, semi-major, semi-minor, conjugate, and transverse axis', and some, I suppose. I still don't exactly know about graphing these guys either. Other than that, I really enjoyed folding the paper, being interactive in a class is always a plus.
Good luck on the test everyone.
Until next time,

Bobbing on Shwards and Things
So, the infamous conic sections unit was completed late last week, and this would be a bob for said unit.
Where to begin? the good? the bad? the ugly? Lets start with the ugly
THE UGLY *dun dun dun*
-GRAPHS! Yes I'm terrible with graphs but I am getting better at them, thanks to a certain "perspective." More on that later though.
The Bad
Not to much here this time, thankfully.
-One of the most difficult parts of this unit is how most of the equations, have another equation which is nearly identical. This made memorizing/remembering which was which difficult at times.
-Going from standard to general form, and remembering which is which was often a pain.
The Good
-Short unit
-Easily understood by used of "visual" tricks (what I meant in the ugly section. By thinking of what the graph of some equation looks like, the question is often made much easier.
-Overall the concepts in this unit, and the difficultly level of the questions was not very demanding.
So yeah, there is it, my small and not very impressive bob post. :P Now I'm back to studying haha.
Ciao!

BOB For Conics
This was a short unit that I was hardly there for because of the music trip to Moosejaw, which was fun, buut now it's time to get back to school and all that piled up work that I have to catch up on. Whooo.
Missing classes for a long period of time has never been a good thing, especially if it's your weakest, and most especially if it's pre-calculus. But some things can't be helped, I think. Well, either way I get in trouble soo..
The concepts were all there for me. Probably the hardest part of this unit was breaking down the question and figuring out which numbers I could use to make an equation. Of course graphing was hard (when is it not hard), but after you have that image, it makes everything so much easier. Everything could've probably been more straight forward if I was actually there (I'm not much of a self-learner when it comes to math) and that's just my fault I guess. Honestly, I'm not looking forward to this test, but I don't know, I think I've done what I can. Hope for the best I guess.
Hahah, as if I'm the very last one to BOB (I think so anyways), but better late than never. Good luck everyone.

BOB: Conics
Time to Bob! (:
I'm quite happy that this unit was pretty short but I'm not going lie because truth be told, I did have some trouble in a few areas. The most trouble I had in this unit was graphing the parabola and I have no idea why I find that difficult compared to the others. The circle, ellipse and the hyperbola were probably the easiest because it was sort of similar to each other. I suppose I had trouble with the parabola because the formula seemed much different compared to others because it included 4p. Hopefully, with a bit more practice I'll feel much more comfortable graphing them. (:
The best part of the unit was folding the paper and visualizing the geometry in each conic section. I would probably have a harder time understanding the whole unit if Mr. K just explained each conic section without folding the paper. Though it took a lot of time and made me quite frustrated beacause the paper wouldn't fold the way I wanted it to, it helped me a lot to understand the anatomy of each conic.
Overall, this unit was pretty straight forward and hopefully I'll do better on the test on Thursday than the pretest we had today. *cross fingers and toes* Goodluck to everyone! Ciao! (:
PS. school's almost over! yay!!

BOB for CONICS
Here is my BOB for the unit Conic Sections.
What more can I say than .. "I've missed too many classes" ..
Although I've missed probably more than half the classes for this unit, it really seems like a fun unit. It seems like a unit that involves lots of algebra and equation handling. Anyways I'm hoping to participate in this last couple of days in this math class. Good luck to everyone! Especially me. I've read the blog, but it might not be enough. Hope I can keep up.
- This is Elven, cheers.

Bob for Conics
*Sigh* What a nice time to have a long weekend. Now I can bob early.
Anyways, this unit was really fun! Not to mention it was also short and simple. What really helped make me understand this unit more was the folding exercises with the ellipse, parabola, and hyperbola. Yes it really did help I'm not just making my bob extra fluffy this time XD. Folding was great for homework assignments too! I usually have trouble with anything that deals with graphing but not in this case. I found it really simple and *coughs* I enjoyed doing them. But what I'm worried about is mixing up all the standard formulas for the ellipse and hyperbolas because they're so similar. Other than that there wasn't anything that troubled me surprisingly and I'm really confident with this unit! Hopefully I'll still feel the same way about this unit after we get through word problems.

BOB Version 6: Conics
Haha I like Ben's creativity... Unfortunately, time isn't a luxury for me.
Anyways, this unit was nice and short, even though the unit had an emphasis on graphing. Once I was able to visualize the graph in my mind's eye--the expression that Mr.K likes using--graphing the graph made things a lot easier, including the origami portions of the unit as well.
Along with remembering the terms, remembering the equations of the circle, ellipse, parabola, and hyperbola is a bit of a doozy, but mathematics is the science of patterns, and contrasting and comparing the formulas between the horizontal and vertical orientations really helped.
I really liked the shward fiasco, the horrible dubbing by DJ K, and his whole samurai act. We may have been fooling around excessively during that class--like what Benz says--but that's what gives this unit its uniqueness. (And maybe there's going to be more unique classes like that when we enter AP Calculus.)
There were some questions left unanswered though, like how golf is evidence that aliens visited our planet Earth and how the focus of the circle is infinity, but if time really isn't a luxury for us, then I guess it's understandable, seeing that THE PROVINCIAL EXAM IS ONLY 14 SCHOOL DAYS AWAY.
If I were to rate this unit, I would give it 5 stars, for being nice, short, unique, and fun.
P.S. Vote ZEPH for V.P.

Conically BOBING
The Conics Unit was pretty simple. The thing that really helped me in this unit was actually visualizing the geometry of each conic section. I started to see how each formula was related to the sections. Overall I'm doing fine so far in the unit. Just like what happened during the quiz. The circles and ellipses were easier to work with than the parabolas. I guess it was because that the
circle formula didn't change at all and that the ellipse formula
was very similar to the circle formula. The parabola
formula was a bit of a change. The a became 4p
and there are 2 binomials now. But it is like
what they all say, "Practice makes
perfect!" The Hyperbola
is still pretty new to
me but what I
noticed
was
that it
used a lot
of our older
analytic geometry
skills to graph the section.
It used the linear graphing skills
as well as many others. Now for my
thoughts about the class. I'm sorry if I am
being a bit mean but I would like it if we stayed
on task a bit more. It just seems like we were fooling
around quite a bit excessively, especially during the second
period. We would get a lot more done if we stayed on task. I don't
mind if we do have a little fun. But it would be great if we toned it down
just a tad. That's all I really have to say. I'm looking forward to the DEVs and
the exam. I'm not really nervous about it at all. As you can see I'm having some fun with my BOB. I am also looking forward to the word problems with conic sections as well as the test that is coming up. So until next time good luck on the test and YAY Calculus is going to work out. Calculus class of the future. Bye and TABBERNACK

MY PREMEDITATED COMBINATORIC BOB
Cominatoric BOB— sounds like a transformer or a robot or something. IRON MAN! eheheh Look at us and our shameless plugs, advertising movies. I am a sublinminal message. Anyhow, I know this is almost really late, but I couldn’t BOB previously because I don’t have internet access anymore. It’s a long story. So I wrote this on Microsoft Word and I’m going to paste it on. I have to admit, this was a fun unit. We learned about “counting” how could that not be fun? But straight to the point. These are only some of the things I learned this unit:
- There IS a difference between PICK and CHOOSE
- A combination lock is not really supposed to be a combination lock, but rather a permutation lock because the order of which the numbers are inputted matter.
- 49 nCr 6 is the actual number of different combinations that can be entered in 6/49 lottery which totals up to 13 983 816. What an investment that is…especially for those depending on it. Sorry for the sarcasm, but I just had to say.
- A circle was once again to be proven as such a special case as we subtracted 1 so that it is the REFERENCE point and then chose a number.
- Pascal’s Triangle [STOLEN] contained many different patterns and sequences, especially sequences significant to quadratic functions and whatever they’re called if there are more than just four…They deal with binomials so to say.
- Poker is a game of chance! [not factorial, but I mean it. Don’t gamble. Count cards and play Blackjack. It works…Winner Winner Chicken Dinner]
On the other hand, we all have our troubles, and these were some of mine:
- I still sometimes have a hard time knowing whether or not the problem deals with factorials or not. Because it could be using exponents like the one question in the pre-test with the number of questions vs. the number of answers. (4^20)(5^10) or something… with four being the possible number of answers to the twentieth because there are 20 questions classified this way and five to the tenth.
- Remembering how to calculate the chances of getting each type of poker hand when you’re considering what suit it is, how many there are, etc…
- When to normally multiply and not use factorials, I think it was also something Mr. K mentioned also.
I know this BOB was a little paint-by-numbers but I think I reached the objective of why we do these BOB’s. I didn’t actually entertain much, but that doesn’t matter because I did actually REFLECT today and I hope I’m ready for the test today. I’m going to slash it with my conic shward. You have to love subtitles and dubbing.

BOB Version 5: Combinatorics
I didn't like this unit. This unit wasn't very orderly like logarithms where there was sort of like a "process" to answer a question. Studying this unit felt studying like something that's abstract, but nonetheless, this is math. Although there wasn't any graphing to do...
I was a bit slow in this unit at first (and yeah I'll admit I struggled a bit), but I managed to learn the basics of permutations and combinations. The poker combinations took a while to wrap my head around, so I may still not be comfortable doing those types of questions, although being scribe for the class on the poker combination class really helped.
On the other hand, learning about phi, the Fibonacci sequence, and Pascal's triangle was... is eye-opening a good word?
Well, I hope I do at least satisfactory on the test today. Good luck.

Bob(ing for Combinatorics...instead of apples)
Haha I just realized I make up my bob titles as I decide to write the bob itself. Thus the title is basically just a direct brain to keyboard link of the first thing that pops into my head :]
Anyways to the point, the unit combinatorics (also known as counting, for those who missed that little piece of unit defining info.)
For starters I'd like to say that I thoroughly enjoyed this unit, a first for any of our units to date. Now that isn't to say that Mr.K didn't teach the other units adequately, I just had to really work at those ones to even get semi decent at them. This unit on the other hand, came kinda easy to me (some of it anyways) and thus, I enjoyed it!
Some of the things I liked about the unit were...
- The practicality of it. This unit gave me alot of knowledge that I can *gasp* actually use in REAL LIFE!!!!11!111!!!11!1!
- The fact that it wasn't really concept, or practice, or anything extensive, but seemed to have just the right amount of everything in it (unlike some other units *cough*logarithmsandUNFUNexponents*cough*)
- All the clever little things we learned along the way, that were totally unrelated to the unit itself. (We should have more of these)
- All the clever little things we learned along the way, that were actually related to the unit itself (and these also)
- The whole unit? Almost
On the other hand (or the second option here, which would be 1 choose 1, because I already went over the first topic.)
I didn't so much enjoy
- The formulas. Overall I found them bulky, and annoying, and hindering to my understanding of the unit as a whole. They just made everything more complicated I think.
- The algebra involving the whatever choose something else, and or the whatever pick something else. The whole factorial deal kinda gets me sometimes (errors with my algebra cause of the ! in the middle of it. Makes no sense I know.)
-The fact I left this bob till so late (I was horseback riding for my sisters birthday party. There goes half my day D:)
So ja, overall this unit gets 8 out of 10 justus league points, not 10, because I didn't much enjoy some of the algebra involved in it but meh, its pre-cal, OBVIOUSLY theres going to be algebra, so I'll just get over it then.
I think thats everything, so I'm going to study for awhile, then sleep, then hopefully mega super power up overshield bxrrxyy final boss strongside ogre 2 wavedash fox shine infinite aleph not pwnzor the test tomorrow. I wish you all the same amount of goodness on your tests :]
Goodnight! and Ciao!
Justus - out, and studying now.
Edit: ohmg! I just remembered I'm missing like a bajillion delicious box links. I'm super sorry guys I forgot all about that thing until I scrolled down and saw it D: I promise to go and find a bunch of super kewl links tomorrow, like lots of them, cause I owe you guys -_-; Hopefully you can find it in your textbooks (or TI-83's) to forgive me. :]
Okay, now I'm really gone :p

Now that isn't to say that Mr.K didn't teach the other units adequately, I just had to really work at those ones to even get semi decent at them. This unit on the other hand, came kinda easy to me (some of it anyways) and thus, I enjoyed it!
Some of the things I liked about the unit were...
- The practicality of it. This unit gave me alot of knowledge that I can *gasp* actually use in REAL LIFE!!!!11!111!!!11!1!
- The fact that it wasn't really concept, or practice, or anything extensive, but seemed to have just the right amount of everything in it (unlike some other units *cough*logarithmsandUNFUNexponents*cough*)
- All the clever little things we learned along the way, that were totally unrelated to the unit itself. (We should have more of these)
- All the clever little things we learned along the way, that were actually related to the unit itself (and these also)
- The whole unit? Almost
On the other hand (or the second option here, which would be 1 choose 1, because I already went over the first topic.)
I didn't so much enjoy
- The formulas. Overall I found them bulky, and annoying, and hindering to my understanding of the unit as a whole. They just made everything more complicated I think.
- The algebra involving the whatever choose something else, and or the whatever pick something else. The whole factorial deal kinda gets me sometimes (errors with my algebra cause of the ! in the middle of it. Makes no sense I know.)
-The fact I left this bob till so late (I was horseback riding for my sisters birthday party. There goes half my day D:)
So ja, overall this unit gets 8 out of 10 justus league points, not 10, because I didn't much enjoy some of the algebra involved in it but meh, its pre-cal, OBVIOUSLY theres going to be algebra, so I'll just get over it then.
I think thats everything, so I'm going to study for awhile, then sleep, then hopefully mega super power up overshield bxrrxyy final boss strongside ogre 2 wavedash fox shine infinite aleph not pwnzor the test tomorrow. I wish you all the same amount of goodness on your tests :]
Goodnight! and Ciao!
Justus - out, and studying now.
Edit: ohmg! I just remembered I'm missing like a bajillion delicious box links. I'm super sorry guys I forgot all about that thing until I scrolled down and saw it D: I promise to go and find a bunch of super kewl links tomorrow, like lots of them, cause I owe you guys -_-; Hopefully you can find it in your textbooks (or TI-83's) to forgive me. :]
Okay, now I'm really gone :p
BOB FOR COMBINATORICS
This unit was very, very confusing. From beginning to end, it didn't seem to let up. Well of course that depends on me as well. I basically missed a quarter of the lessons which really hurt what I could be capable of learning. My brain literally feels empty. I mean we might have not gone through a lot of workshops or work thoroughly with this unit. Or perhaps I wasn't just here, and haven't been doing my homework.
I wouldn't say that it is hard to catch on. For me though, having to miss many classes and was not catching up, had even more trouble. It was slow for me to come up with solutions and ideas to solve problems.
I found the poker combinations fairly easy though.
Overall this unit for me was a failure. I shouldn't let this slip away again. I've got homework to do!
Cheers!

BOB For Combinatorics
well this is my bob for Combinatorics. When we started this unit i thought that counting should be a piece of pi ah ah get it (pi 3.14 ) anyways this unit was a lot harder then i thought it would be. well it wasn't harder then logs but it was still a little confusing.
One of the things that confused me was the circle table questions. another was that zero is definitely a problem. And the one that really caught me of guard was that if it is bracelet it is a whole new ball game.
and now that my xbox is broken because it has got the red rings of death. i guess i will study now

When I heard counting I thought, "Weeell, how hard could that be?" It turns out, pretty hard. It didn't take me long to realize that counting, was like probability, and I don't like probability. =/ Just like I didn't enjoy this unit.
It was probably the wording or word problems that got me. I also didn't like how sometimes you had to experiment until you got it right, kind of like Trig Identities.. except less fun. It took me a while to understand 'pick' and 'choose'. Well, not really understand, understand, but it took me a while to see how to apply it, I guess. There were a lot of stuff in this unit that made me go, 'what?' at first. It's just, a whole bunch of numbers everywhere. Especially with the binomial theorem idea. But after I noticed the pattern, it wasn't too bad, though I still had to concentrate so as not to lose track of what I'm doing. There was that one question we did in class where I wasn't really paying attention and I ended up missing b^1 so the whole thing ended up being wrong. So yes, I have to pay attention.
I didn't like this unit, honestly. I'm happy and sad at the same time that the test is tomorrow. It's like, "Yes! The test is tomorrow! IT'S OVER!" and then at the same time it's like, "OH NO! The test is tomorrow!" Youu know? Hahah, I agree with Kristina, I miss logs too.

ComBOBinatorics
Combinatorics. I found this unit quite easy at the beginning. It was one of the units I felt very comfortable doing, 'cause more or less, it's just combinations and permutations. After that, it got a bit harder, with the whole poker hands and what not.
Basically you just had to focus on what was being said.
The Pick and Choose was easy enough to grasp, but then after that you throw in restrictions and all that which created a bit of a turmoil for some people, including me at times. At first, the table question stumped us all, and then we understood it after we got the whole reference part down because you know, a circle doesn't end =P
Then after that, bracelets threw us off because we thought "oh, it's just like the table." But it wasn't. Bummer huh.
I mostly had trouble with the poker hands, with all the choosing and restrictions =/
Overall, this was a good unit for me. Nothing tricky, I just have to observe it closely. Look for the clues, and you'll know what to do more or less.

BOB on Combinatorics
During the first class, I was quite excited because I was pretty anxious to learn how to use simple equations and numbers to figure out the chances of a certain subject, such as how many ways can 3 people sit in 4 ways. I thought that was pretty cool. At first it was really simple with the factorials, I got my head around that quite quick, my head lassoed those factorial no problem. Then we fondled with permutations and permutations that include 0's. Those were slightly more challenging but nevertheless, I eventually came to understand those as well.
Now circular permutations were just plain frightening. Then Mr. K explained it, and I was still confused which made me even more scared. Then he gave us an equation: (n-1)!, that was easy enough to memorize, and I wasn't so worried anymore. Same with bracelets, the only difference being that you can flip them, so just divide the equations by 2: (n-1)!/2.
Pascal's triangle, seemed to be difficult at first, but I started to notice simple little patterns, then learn more challenging patterns, like the Fibonacci sequence, and the hockey stick sequence, that I probably would have never discovered. Phi was pretty cool, learned a bit of photography that class. It was interesting to know that "Phi" was attractive, and how the ancient Greek's knew about Phi and how they built an entire temple with objects that were related to Phi. The binomial theorem was challenging and I don't understand everything about it, but I should do just fine.
The last thing were the Poker hands. That class, I really felt like playing poker, but then my head started to spin, with all these different equations put together like a puzzle with so many rules put into play, I didn't really get it. I hope I won't flunk this test, like I flunk in actual poker. Good Luck on the test everyone.
