Logarithms

1. logb AB = logb A + logb B
2. logb A/B = logb A – logb B
3. logb A^n = n logb A
4. logb 1 = 0 therefore logb 1/A = -logb A
5. logb b ^n = n
6. b^ logbA = A
7. logb A = log A / log b
8. logt b = 1 / logb t

lnx = loge x

Properties of a log graph
x int: (1,0)
V.A. x = 0
increasing if b>1 // decreasing if 0 < b < 1
Domain: {x e R | x /=/ 0}
Range: {x e R}

Richter Scale:
M = log10 ( I / Io )
Sound:
L= 10 log10 ( I / Io )
Chemistry:
pH = -log [H +]

So I have a math test tomorrow, and I'm so not ready x.x I would get off the comp and stuff, but I don't think that will help me much…
Anyways, I'm going to run through the review and hope I pass tomorrow !

I just saw the weather and it's like 32 degrees Celsius on Tuesday WITHOUT humidex, which means it'll be like, what, 47 degrees WITH humidex? OMG I'm going to die…

Course Selection!

So it’s that time of year when we have to choose what courses we want for next year. And it’s seriously giving me stress. In the HMST program (hate hate hate hate hate) we have to take chem and physics, math and advanced functions, and tech, plus the mandatory English, leaving us with only 2 electives. I’m thinking yearbook, and accounting, or maybe tech? Sigh… I am the most indecisive person on earth… the thing is, the courses we take next year, dictate what we can take next year. In other words (because of the program) people in HMST have hardly any choice to take math and science, since they’ll be like the only thing we have prerequisites for. Saddest part is: I know what I want to take for grade twelve, but unless I fail the set courses this year, I already have the prerequisites set. Sigh… again…

So today, the Olympic event consisted of Ski Jumping (love watching that), Curling (it’s slow, but intense), and I’m not sure what’s on now… I was watching the Ski Jumping, where someone jumped like 144m and no one was able to top it, and then Curling, I watched the game between Great Britain and the USA. I think Great Britain was winning when I left (those games take so long, and I can’t sit for that long, without like tapping my foot off so I had to leave…)
Currently, USA has obtained 21 medals, Germany has gotten 14, Norway has racked up 10, and Canada’s got 8. (Woot! We won Men’s Skeleton~ Yay Jon Montgomery!)

Where is this ‘break’ you speak of?

Teachers talk about long weekends, winter ‘breaks’, march ‘break’, etc, etc. And yet, there is never an actual break from work. Over a four day weekend, there were tests to study for, and presentations to prepare. Over Winter Break, there was a science project, history ISP, math ISP, and careers ISP. Either my definition of ‘break’ is different from the school’s, or the teachers’ or the TDSB just like breaking rules. I thought it was illegal to give more than 2 hours of homework to students, per subject, per night. And yet here I am, staring at about 2+ hours of Biology homework. And I thought teachers weren’t allowed to give homework, projects, etc during breaks or on holiday weekends. So unfair….

The snowboarding event seemed to be doing okay, last time I checked (which was about an hour ago…). Canada was in third in the second run, though it’s hard to hold a place unless you’re first. Even then it’s hard.
Currently, the US hold 8 medals, Germany 6, France 6, and Canada has 4. At least we’re fourth. Hopefully, we get something for snowboarding. It seemed like the lady in third was doing pretty well, though the Switz competitor was REALLY fast, having a time of only 24.45, I believe. That’s crazy! Everyone else kept wiping out on the course… A lady from Australia took a huge, and painful looking wipeout on her second run… while a Japanese woman didn’t fair much better… I think the Canadian course is a little slippery…

In English, we wrote a journal entry from the perspective of one of the characters. I chose Ralph… which I kind of regret, since the people doing Piggy or Simon would have their journals a little shorter than I will….

Bio presentations was…. okay… forgot to do the ‘hook’ at the beginning, though… C’est la vie, what’s done is done. Then tech presentations seemed to go over well, after my stupidity, and a moments panic…

See, I’d say I hate Mondays, but it’s Tuesday, so that really wouldn’t work.

Currently: Doing my bio homework….

Reading: Er… I need to find a book… preferably one from the library… it’s free.

Two More Left

I have…about three more hours until my history exam. And I just don’t feel like studying. Basically, I’ve hardly studied at all. Either I’m too lazy, or my friend RD is wearing on me, and I’m beginning to lose all initiative in school. The saddest part is, RD gets 90s without doing homework, trying on tests, or listening in class, while I get 60s for paying attention, taking careful and neat notes, and studying like hell. Who wins? He does. ALWAYS.

So, with my epic distractions come my friends. I’m talking to them, and there’s stuff about anime, youtube videos, and french. But no history or science cramming. Just random ‘Look this is funny!’ kind of videos.

Here’s one of them:

See that’s both entertaining and mildly disturbing.

Two more exams to go. Two! Today and tomorrow, and then the torture is over… until June. So, when I get back tomorrow, everyone will get to hear my rant about school! Yay! And then I’ll crawl into my little corner and read all the books I had taken out from the library, and shove all history and science facts out of my head. Though I’ll probably need those next year… Who knows what might happen.

*Cries* I may make it into Gr 11 Honours Math Science and Tech. Which is the program I’m in now, but I might actually pass through. That’s good on one side, because then I can stay at NV. On the other hand though, it’s SO MUCH WORK. The courses you need to take next year is: Gr 12 Chemistry, Gr 11 Functions, Gr 12 Functions and Relations, Gr 11 Physics, and some Gr 12 tech course. Fun! So much math….*sad*

Historic thoughts for the day:
Hitler did not change history. HE MADE IT. You can’t change something that was never created.
Triple Alliance-Germany, Italy, Austria-Hungary
Triple Entente-France, Britain, Russia
History is dumb, because the Triple Entente are the allies, and yet they aren’t the Triple Alliance. (sigh)

Currently: Getting epically distracted

Lalalala~~

So history is boring me to death and science isn’t any better. Only two more! I tell myself that, but that doesn’t make me feel any better. Especially with this freaking cold….

Math fact for the day:
Alikiya+studying=epic boredom. See, with just that, I should get an A in math~
If only….

So I should really get back to studying, though I probably won’t. I’d either get distracted, or I’ll just sit there, staring at the review sheets and think ‘Why can’t monkeys fly?’ I swear, I can be Einstein! Starting… Never… It’s odd though. I can memorize music lyrics faster than anything, but when it comes down to scientific or historical facts, it just flies over my head to be forgotten. I can remember the stupidest of things, and when it comes down to school, everything slips away as easily as water. Sigh. My common sense is somewhere up there, and yet my math skills are about rock bottom.

I think I’ll just be a hobo when I grow up. Aim low. Shoot high!

Currently: Testing my friend in history. That’s the closest I’ll get to hardcore studying

That is what happens when I’m bored… hehehe~~

Good luck with exams!

It Is FINISHED!

Math. Is. Done. No more. GONE! Yay!! *does a funny dance*
So happy~

I missed a question at the end of the exam. I just blank. It was the last question though. I think my mind just decided to stop to take a breather. Overall, though, I think I did well *crosses fingers* But we’ll see by Feb 3rd.

For my history exam, I am going into it with an 85. My lack of minutes for my presentation made it drop by five… so hopefully exams bring it back up~~ As for science, I’ve got an 83 going into the exam. I need to get that up. I’m determined to get a high(er) average.

But for now, I think I’ll just relax for a while~ I’ve worked my butt off for the math exam. Tomorrow, or tonight, I shall begin doing so for my history and science exam!

Currently: listening to music, while writing.

Cram Time

Tomorrow is my math exam, which I have repeated about 382498237 times this month. Sorry for that by the way…

It’s cram time. But not too much, or you’ll forget everything.

I think I’m ready. I hope I’m ready. This year, I will not flip out of my chair (you don’t want to know) during the exam! (I’ve already done that in science this year….) I try to defy gravity way to often. I should seriously stop….

^^ I saw some of my old friends on my way back home. Oh how I missed them. We stood outside in the cold for and hour talking about school, life, gravity testing, etc. That was a fun hour~ Totally lightened my mood. And then I remembered, math. Then I though: “Dang, should have ask my friends for help.”

I’m so bright!

Currently: Cramming…
