2003-03-23 [akhirah]: i guess i shud learn more math, since thats not my strong part..

2003-08-27 [Tal Anduril]: Anything you could tell me about differentiation or integration would be great

2003-09-18 [Silversong]: trig is alot of fun.....I could play tutor for your class if you want.....I don't know everything but I can help whenever I know whats going on!! Smiles!! ~Silversong~

2003-11-04 [thrantos]: Statistics class... I'm so not doing well. :(

2003-12-07 [Urizen]: AHHH I HATE CALCULUS!!! I"M RIGHT IN THE MIDDLE OF THIS ONE problem and i totally forgot how to find the area under a curve on a graph.... evils... i hate it. stupid brain farts

2003-12-12 [Nairda]: integration

2004-04-10 [lyna]: Geometry.....evil evil circles with their arcs and chords....any hint or tricks i can use on a test that you can share?

2004-04-17 [shotokan_gal]: Ohh maths... never even knew this place was here. If you want help with it, I'd be happy to occasionally, being rather good at it. But is it a full time job? Hmm... times an issue

2004-05-16 [i am jack's box]: I am pretty good at geometry, if you have any questions, email me. I prefer you have a scannner so i can solve them out and teach from there

2004-05-20 [Tári Nénharma]: I'm sorry, but my goal in life is to be a math professor. I've taken four calculus courses which could aid our older Elftown constituents, and I have real-life tutoring experience. Contact me if you'd like to see a calculus course (or if the professor wants help or a sub or something). I'm 18. :D

2004-05-21 [mayonayz]: Geometry would be nice to learn...

2004-05-22 [shotokan_gal]: hmm do any of the *owners* of this page actually keep a watch on it anymore? doesn't seem like it really

2004-06-01 [i am jack's box]: need help in geo?

2004-06-17 [LonelyTylenol]: I noticed that nobody seems to be replying to anything... Hey, Tari, I'll learn math from you... Wait, I can do that anytime... (She's my sister)

2004-06-28 [Tári Nénharma]: everyone!! announcement: math is back up. It's wonderful. Check the student list and make sure you're on it!

2004-06-30 [shotokan_gal]: If you're short on teachers... well, what is it you need to teach? And I'll tell you whether I could help or not...

2004-07-12 [Tári Nénharma]: If anyone has a question about what any of the classes are, message me at my house.

2004-07-15 [Amanar]: same here. Math rules!

2004-08-20 [shotokan_gal]: Outta curiousity, has there been any new interest in the classes lately? Haven't been keeping as close a watch as I suppose I should've done.

2004-08-21 [The Crazy Chicken From Family Guy]: im a new math teacher

2004-08-21 [The Crazy Chicken From Family Guy]: i dont know which class ill teach

2004-08-21 [shotokan_gal]: *raises eyebrow* hmm?

2004-09-10 [Tári Nénharma]: hmm?

2004-09-10 [shotokan_gal]: It was at the dragon hunter dude... but nevermind, he seems to have scarpered.

2004-09-12 [Sunrose]: Teachers please visit ETA Departmental Staff and check up your status! The professor is asked to keep in check of own teachers, so make sure they also report to you: if they don't you have the power yourself to fire your teachers, change their status and hire replacement ([font] can't do everything, so please help him out!) ^^

2004-09-14 [flaed]: If anyone cares to help me with a math/physics problem, feel free to hop on over to the trigonometry department ^_^

2004-09-20 [Firenze]: Does anyone know how to do standard deviation?

2004-09-20 [shotokan_gal]: Depends what sort you mean... theres several. But in short, yes

2004-09-20 [Firenze]: All of it as they have brought in a new way of doing it which is more complicated, I think.

2004-09-20 [shotokan_gal]: New way huh? Well theres various formulas for it if thats what you mean. Would be nice if you were a little more specific. By the way, are you an a-level maths student?

2004-09-20 [Firenze]: AS

2004-09-20 [shotokan_gal]: Oh yeah... as, a-level. What I meant. S1 then I take it? Think I've still got my old notes around somewhere...

2004-09-20 [shotokan_gal]: And yeah a lot of stuff gets more complicated after gcses. Those are too easy really (know you probably don't feel like that now, but you probably will by the end of the year!)

2004-09-20 [Firenze]: Yeah I am doing S1, the notes my maths teacher weren't that clear and she expects us to do 20 questions by tommorrow and we only got the questions today.

2004-09-20 [shotokan_gal]: Lovely... well, you've got a textbook right? Don't know which sylllabus you're on, but the ones I did were rather good for examples which were pretty much carbon copies of the questions in the exercises. Anyway, these all standard deviation questions? Post one and we'll see what we can do with it...

2004-09-20 [shotokan_gal]: and I really ought to find me old notes... won't be a minute

2004-09-20 [Firenze]: Okie Doke!

2004-09-20 [Firenze]: I know how to find the mean of the question, but I don't know how to do the rest, so I will send the questions in a message ok.

2004-09-20 [shotokan_gal]: Rightio...

2004-09-20 [Firenze]: sent it

2004-09-20 [shotokan_gal]: Right, well, this stuffs a little hard to write out in type... so gimme a minute. You've got the standard deviation formula though I assume?

2004-09-20 [Firenze]: Yeah I have that

2004-09-20 [shotokan_gal]: Which one is it you're using? If you can write it out in words... (I'll know what you mean)

2004-09-20 [Firenze]: Square root Sxx/n-1

2004-09-20 [shotokan_gal]: Sxx... is that the sum of (x - m)^2? m being the mean... which did you get 2.36 for?

2004-09-20 [Firenze]: yeah I got that, I think *Checks Notes*

2004-09-20 [Firenze]: i got that, its the root square mean deviation i don't get

2004-09-20 [Firenze]: don't worry about it my mate who is in the same maths group as has just phoned me I will ask him, thanks for your help, by the way what subjects are you studying or have you studied?

2004-09-20 [shotokan_gal]: Well, I'm writing out the working of the standard deviation on a wiki page at the moment which I'll direct you to in a sec... but whats this root square mean deviation thing? Just the sd?

2004-09-20 [Firenze]: I will send you through the equation

2004-09-20 [Firenze]: square root Sxx/n = sqaure root 1/n Side ways m(x-xwith a hat on)squared

2004-09-20 [Firenze]: Confusing I know

2004-09-20 [shotokan_gal]: lol thats ok... the 'side ways m' I think you'll find is sigma. which means the sum of

2004-09-20 [shotokan_gal]: x with a hat on would be x bar... the mean

2004-09-20 [shotokan_gal]: so really the only difference between the two formulas is ones over n - 1 and ones over n right?

2004-09-20 [Firenze]: yep

2004-09-20 [shotokan_gal]: I think the real problem you're having is the notation. I've done it in the form of a sort of table there.

2004-09-20 [shotokan_gal]: (hope the answers are right)

2004-09-20 [Firenze]: The answers are correct from what I can tell, I think your write about the notations, thanks for your help you have really cleared up how it works, thanks a million ^_^, you're a wiz at maths ^_^, thanks again, now hopefully I can get on with my Chemistry homework as well.

2004-09-20 [shotokan_gal]: Did you follow the steps ok? I didn't really write much description. But its been no problem, glad to help, and hope it did help you get it.

2004-09-20 [shotokan_gal]: Hehe... and I should be good at maths really. I'm doing a degree in it after all ;)

2004-09-20 [Firenze]: the steps are easier to understand compared to the ones given by my maths teacher

2004-09-20 [shotokan_gal]: Well thats good, I tend to always do this sorta question in tables. The only problem you'll find after a while is it takes so damned long! (especially the more data there is). Anyway, feel free to come back should you need anything explaining and we'll do our best here to sort it out. (damn, I sounded so much like an advert there!)

2004-09-20 [Firenze]: Ok, by the way if you are studying chemistry and having a hard time send me a message ^_^

2004-09-20 [Mohazy]: nice job [shotokan_gal]

2004-09-20 [shotokan_gal]: Hehe... ok, will do

2004-09-20 [shotokan_gal]: Thanks [Mohazy] :) Nice to do some teaching at last

2004-09-20 [Firenze]: ^_^

2004-09-20 [Mohazy]: yep a college without students is so boring,[Firenze] gave us some stuff to do,by the way u can always check the final answer using the calculator, i mean the standard deviation

2004-09-20 [Firenze]: Well I'm always glad to help, and you will probaly have a load more questions asked later on in the year

2004-09-20 [Mohazy]: good,we are ready for questions really

2004-09-20 [Firenze]: *smiles* no offence but I hate maths but I need it for the course I want to take in university

2004-09-20 [Mohazy]: well maths is much more fun when u study applied maths not theoritical maths, maths is so important in my study (automatic control)

2004-09-20 [Firenze]: Cool, well at the moment I am studying English Lit, Maths, Biology and Chemistry(The most amazing subject ever, lol), so I am studying these subjects so I can study forensic pathology

2004-09-20 [shotokan_gal]: Well now thats a matter of opinion :p I prefer pure maths by far. Dropped mechanics after my first year, and now the stats modules after my second.

2004-09-20 [Firenze]: we're doing pure maths and stats

2004-09-20 [Mohazy]: my opinion is that,for example when solving a system of differential equations u will enjoy it more when u know the varable (x) for example represents a current of voltage in a control circuit for example

2004-09-20 [Firenze]: i hate physics so don't get me started on it

2004-09-20 [shotokan_gal]: Woo! I like her ;) Just overcomplicates things in my honest opinion. Give me pure algebra any day.

2004-09-20 [Firenze]: yep, and I mean it I am terrible at physics and hated the subject more than RE. I would rather sit and do simutaneous equations all day rather than physics (evil subject!!!)

2004-09-20 [Mohazy]: haha, its just opinions as u said dear

2004-09-20 [Firenze]: yeah ok ^_^

2004-09-20 [shotokan_gal]: Yep. But its two to one so :p

2004-09-20 [Firenze]: ^_^

2004-09-20 [Mohazy]: haha i can ask my whole university join Elftown

2004-09-20 [Mohazy]: it would be 2 to 2800 lol

2004-12-12 [Tári Nénharma]: Pure Math is my favorite too (ha!). Thank you for the official banner, [Sunrose]! And [Firenze], don't forget to actually sign up for the class!

2004-12-12 [Tári Nénharma]: ... hmm, I just noticed that I haven't been watching this wikipage! Well, from now on I will receive notices when the comments are updated, and so I can keep up! Silly me!

2004-12-12 [Firenze]: I have dropped maths at 6th form so I no longer need any help until next year maybe ^_^

2005-03-21 [bluefarie]: hey, what catagory would proofs fall under...?

2005-03-21 [shotokan_gal]: Under whatever it is the proof of. Do you need some help?

2005-03-21 [bluefarie]: *logically equivalent*  i will in the future....b/c right now we're doing the easy 1s....but, i know the harder 1s r coming up.....

2005-03-21 [shotokan_gal]: Fair enough. You can always post questions in the comment box, since we don't really have enough students to have many classes running right now.

2005-03-21 [bluefarie]: ok...i put my name in the elementary logic.....

2005-03-21 [shotokan_gal]: Teachers - I took the liberty of adding a little edit to the page up top. Seeing as we don't have many classes but in case those come seeking immediate help.

2005-03-21 [Mohazy]: nice u r first student i guess in my class

2005-03-21 [shotokan_gal]: Ah, I was just about to direct them in your er, direction ;)

2005-03-21 [Mohazy]: i was starting to feel bored from empty classes

2005-03-21 [bluefarie]: its ok...im here now...yay! *ouch...damn headache..*

2005-03-21 [Mohazy]: cool, so what u r studying about elementary logic? or i mean what u would love to know

2005-04-21 [Estantia]: ooh! I had an idea...

2005-04-21 [shotokan_gal]: Yes? Don't keep us in suspense ;)

2005-04-24 [Estantia]: had is the word... i forgot it... i think... wait... message to Tari needed...

2005-04-25 [Estantia]: would vectors be a good idea?

2005-04-26 [Tári Nénharma]: yes, and we can have a sub-tutorial for vector operations without having a whole vector class

2005-04-27 [Estantia]: that's good... as i said, you'll have to do the really advanced vector stuff though.

2005-05-01 [elfgirlk]: im a newbie. can sumone help me i need help wiv pre-calculus plz

2005-05-01 [Estantia]: of course, what do you need help with?

2005-06-12 [Dil*]: If your classroom is messy, please fix it with classroom template - [ elftown academy crew ]

2005-07-22 [Estantia]: is it messy? this is neat compared to some.

2005-07-22 [shotokan_gal]: I think that was probably just posted on all the department web-pages, as well as probably refering to the actual classes rather than this page :)

2005-07-22 [Estantia]: true, but someone's actually taken the time to write it so...

2005-07-22 [shotokan_gal]: To give uniformity to the classes? *shrugs*

2005-07-22 [Estantia]: true, but some subjects don't work if you have it like that, take metaphysics for example, lessons just don't work.

2005-07-22 [shotokan_gal]: Well, I wouldn't know personally. I'll take your word on that.

2005-07-22 [Estantia]: good idea... basically the debating subjects.

2005-09-14 [elfgirlk]: pre calculus pleeeeasseee?

2005-09-14 [shotokan_gal]: What exactly do you want help with? Post a query and we'll answer.

2005-10-21 [Tári Nénharma]: I guess I'm inactive, huh? Maybe I'll come back on. And maybe I'll concentrate on my own studies? I'm in such a whir (see mood).

2005-10-21 [shotokan_gal]: Ohhh excitement. I assume they just go through the list occasionally to weed out the members who haven't been online a while.

2005-10-21 [Estantia]: yes i guess, I still haven't made a class... *groaned*

2005-10-23 [shotokan_gal]: I'm still meaning to make some for probability. Though geometry, I really don't have time for that, or know what level would be appropriate.

2005-10-23 [Estantia]: i was going to do vectors until someone took it.

2005-10-23 [shotokan_gal]: Someone took it? Didn't even think there was a vectors class. I say, if you want to write a class, go for it :P at least then people can check them out when they visit rather than just see a load of empty classrooms.

2005-10-26 [Tári Nénharma]: Agreed!

2005-10-26 [Estantia]: yup, ok, all i have to do is find a program that lets me draw vectorson square paper...

2005-10-26 [Mohazy]: mm try matlab, but it will kinda need lots of manual work on the graph paper

2005-10-26 [Estantia]: don't have that, I'll try figure it out in photoshop...

2005-10-26 [That Fuzz]: Hey, um, just out of curiosity... why do the wikis have spaces in the names?

2005-10-26 [Estantia]: because?

2005-10-26 [shotokan_gal]: Well, math (without space) was the old department before [Tári Nénharma] put this one together, and I don't think it was deleted straight away in case the old teachers actually came back online, or something.

2005-10-26 [Estantia]: i see...

2005-10-26 [That Fuzz]: ...Wait, what? I didn't understand what you just said.    You're... hiding from the old teachers?

2005-10-27 [Estantia]: no, because they couldn't use the old wiki and change it drastically in case the old teachers came back and got annoyed that their entire department had vanished without being able to move lessons I think...

2005-10-27 [That Fuzz]: I... see? o_O

2005-10-27 [shotokan_gal]: [Tári Nénharma] took over before the older teachers were properly retired. So that wiki page (if you look at the previous version of it) was left up for a while in case it was still needed. Now it isn't, but we may aswell keep it like this since everything's set up. Make sense yet?

2005-10-27 [Estantia]: yup.

2005-10-27 [That Fuzz]: Fair enough. :D

2005-12-21 [That Fuzz]: If [Tári Nénharma] is no longer the math professor, who do I talk to to become a teacher?

2005-12-21 [Sunrose]: You can apply at Academy Applications :)

2006-04-28 [shotokan_gal]: Erm, have you been approved? :/

2006-04-28 [Sunrose]: Either he didn't apply or it was denied...

2006-04-28 [Estantia]: I don't even know what I'd want to teach...

2006-05-03 [Tári Nénharma]: Congratulations to [Ashita], our new math professor!

2006-05-04 [Mohazy]: i dont think i will be able to continue being a teacher here, i will start teaching in university in 5 months time and i will be studying for my masters at the same time, how can i quit? or i just have to be unactive?

2006-05-04 [shotokan_gal]: Erm, I'm not sure he/she actually applied, or was accepted tari :P

2006-05-04 [Sunrose]: She didn't :P // [Mohazy]: well..if you wish to be removed then I can arrange that. Of course being inactive will get you removed eventually as well.. . Shame though you can't stay here, though very understandable :)

2006-05-04 [Mohazy]: well i think i can continue here for those 5 months(especilly not so many applied for my classes ;) ) , after those 5 months i will see

2007-04-27 [Estantia]: I can teach integration and differentiation, though some of the more complex differential equations either I haven't been taught or need to go over again.

2008-05-23 [Imperator]: [Estantia], might you still be available to create a new math classroom? This department really needs some more help.

2008-07-25 [Flisky]: I'm a history major, but I'm also a math minor if I can help out here. I'll put in an application...

2008-07-25 [Estantia]: the main issue is what I'd teach more than anything, what would you need me to do?

2008-07-26 [Imperator]: Anything! Taking over Algebra would be a great help too.

2008-07-26 [Estantia]: Doing the basic things? I think I could manage that. But most of the students are asking for that help years ago, they'll have passed it by now...

2008-07-26 [Imperator]: I don't think there are any students actually getting schooled anywhere in the Academy. All you would need to do is clean it up and add onto the previously existing information. I noticed that the old algebra lessons were put on a seperate page and new ones were made by the new teacher (who is now retired) so maybe you could combine the best of both or something.
