<0> lol
<1> I must have made that "color screen" thing up
<1> Damn my useless memory!
<0> so...
<0> theres got to be a way to exploit these simple rules
<1> What the heck is a "powerbook"?
<1> ...besides the Apple product...
<0> apple's laptop
<0> other than that i have no clue
<0> unless apple has made a new name for a laptop
<2> maybe they use a separate name to denote that, for a long time
<2> it was merely similar to having a laptop
<1> haha
<2> in the same way that having colecovision was similar to having atari
<3> so, is there an ascii number for the "exists in" symbol?
<1> Wake-up call, College Board: A graphing calculator IS A HANDHELD COMPUTER, YOU DOLTS!
<0> haha
<4> Why does it matter if a calculator uses paper tape?
<2> noise.
<2> they don't want loud things.
<0> thats already given rule tho
<5> they should let peopletake palm pilots or ipaqs in
<0> the no noise rule should take out the paperfed machine
<1> Printer noise, and a printed record that you could sneak out
<1> ...not that it'd do you or anyone else any good
<3> sheez ... what's the best way to type up equations?
<0> heh... sooo no qwerty keypads... does that mean you can use an alternate key layout such as DVORAK ? heh heh
<1> hahahahaha
<1> No, the proctor would simply invoke the ludicrously vague fifth rule, and declare it a "handheld computer"
<0> but i guess that would be considers (typewriter-like)
<4> Yeah, how is a qwerty keyboard different than ABC or Dvorak?
<2> you shouldn't need a calculator on the SATs
<1> That's a good point
<2> in fact, the only cl*** that should have calculators is the AP stats cl***, where you can argue that doing the painful computations is useful
<0> what about ap calc ?
<2> there shouldn't be an ap calc
<0> i'm taking that this year :X
<1> haha
<4> I know I guy who put a TI-89 inside of an 84 case so he could use it on the SAT
<2> all it does is painfully underprepare students
<0> O_O??
<0> HiLander what do you mean
<2> as i appallingly graded the first homework of the semester, i was starkly reminded of that fact.
<2> ap calc teaches students how to memorize rules
<2> i don't know why they need to destroy math
<2> just have them take the bio exam
<0> ack
<0> i hated biology
<1> "Nongraphing scientific calculators, powerbooks and portable/handheld computers, pocket organizers, electronic writing pads or pen-input/stylus-driven devices (e.g., Palm, PDAs, Casio Cl***Pad 300), devices with QWERTY keyboards (e.g., TI-92 Plus, Voyage 200), and cell phone calculators are not permitted for use on the AP Calculus Exams."
<2> anyway, it tricks students into thinking they've learned calculus
<1> I think the rule against "nongraphing scientific calculators" is hilarious
<1> You can use no calculator, or you can use a graphing calculator
<6> You can bring desktop computers to the AP exams, I see.
<0> ehm... i haven't seen many good calculators that didn't graph
<1> hahaha
<0> LOL!
<7> Hmm, wonder why that is? /me loves his 30xa solar
<4> I love my TI-89
<0> hmmm on the ap exam.. it really appears that its not against rules to have a desktop
<0> and theres no "no plugging in stuff" rule
<1> HP had a couple of pretty nice nongraphing calculators that could do a lot of the nongraphical things that most graphing calculators do, e.g. numeric solving
<7> Its getting old though, and they don't make the solar version anymore... so Im going to have to get a 36.. yuck.
<7> enginuitor: My 86 can do symbolic solving
<7> er, wait... 89s can too.
<0> bsmntbombdood so are ti-89's not allowed for the SAT ?
<7> as far as I know they are allowed, just not qwerty
<4> ChrOnX: I can't remember if it's the SAT or the ACT they aren't allowed on
<7> And its more of a english restriction, not a math one
<1> My TI-30XA solar developed several dead keys after a few months, so I had to get a TI-36X Solar
<0> hmm.. i would completely put a ti-89 standard in a ti-83+ case
<0> if i had to
<1> The 36X is a pretty good calculator, aside from being butt-ugly
<7> enginuitor: My 30xa solar is still running strong. Its the old style, none of htis new fancy rounded crap. But, they don't make 30xa solars anymore, just battery versions... pisses me off.
<0> haha
<1> Damn Apple users, deciding everything had to be shiny and curved
<7> Well, and the covers are less effective
<4> I might have to get a different calc when I take the SATs
<4> :(
<1> Yeah, the "pop-top" cover is silly
<1> Actually, mine has been dropped and/or thrown so many times that I don't bother with the lid any more
<1> One of the things I like about the HP 50g is that, instead of a weird slide-on cover, HP provides a nice leatherette pouch
<1> Not sure if it's all that good in terms of protecting the calculator, but it *is* pretty :-)
<2> man, what happens if someone shows up and wants to talk math?
<1> I think it depends on the time of day
<2> you're gonna want to limit that as much as possible if you want to survive in here.
<1> Hmm... the AP Calculus calculator guidelines specifically list the HP 50 as being able to "take a derivative numerically"
<1> ...but I'm not sure whether that means there's actually a one-step means of doing it
<1> There's a "slope" function in the graph screen, but that doesn't do me a lot of good
<1> I wish I didn't have to waste my time on this :-|
<8> Hello.
<9> greetings.
<10> you're kidding, right?
<8> Who was the person that said something along the lines of math is accurate only when it doesn't describe the real world?
<8> Or maybe the word was exact
<10> so it's exact only when it describes nothing.
<10> anything else is part of the real world.
<8> I guess you haven't heard the quote before.
<10> although one could argue the world was created from nothing, in which case...
<2> that sounds like the sort of thing einstein or hardy would say
<10> who said "Men are slaves, women are bosses and children are epsilons."?
<2> i don't think erdos said them all at once
<2> but they were part of his lexicon
<10> heh ok :)
<8> Ah, I've found it. It was Einstein. Thanks.
<1> HAHAHA
<1> There's a document that claims it will tell me how to take a "numerical derivative" on an HP graphing calculator, but it costs $3.50
<8> lol
<10> too bad you can't charge for someone trying to think for you
<10> "If you want to advertise, please pay me."
<8> So many school people would owe me money if that were the case.
<1> According to Google, "numerical differentiation" and "hp-50g" don't occur on any one page in its database
<1> occur together, that is
<1> User function time
<1> HAHAHA
<1> Took the "al" off of "numerical"
<1> 33 results
<1> Never mind
<1> Could someone explain the symantic differences between "numeric" and "numerical"?
<1> semantic*
<6> Numerical has an l in it.
<11> hello
<6> If you like adding ls to words, use numerical.
<8> Hi, loconut.
<8> Olathe: but what about the a?
<1> Ah-HA!
<11> greetings dacicus
<8> numerical - l = numerica
<1> You have to enter it as d/dx f(x) | x=n
<6> Dacicus : That's silent.
<6> Nobody likes to add as to words.
<1> ...so *that's* what that little vertical line is doing on the keyboard :-D
<8> You'd think they could use a comma, but, no.
<1> Turns out HP has a 7-page document on the subject of taking a numeric derivative on the HP-50G
<1> I'm not sure why I didn't find it in my *first* hour of searching
<8> :o
<8> 7 pages?
<8> For something that should be simple?
<11> I have a sample size of 32- the average of which is 34086.25 and the std. dev is 193.67.. That 34086.25 is my maximum value- if say I wanted to compute a fraction of it- eg 1500/344086 or 1500/344087- to what decimal place is my data accurate?
<1> Dacicus: One page is the title page
<8> loconut: hundreds
<1> Dacicus: Then they have a number of step-by-step examples
<1> Seems like that would have been a good thing to put in the *user's manual*
<11> thats what i thought because 193.67/34086.25 = 0.005
<11> which meant to me that it was inaccurate at the 1000s
<11> but I'm not a math guy
<1> Not necessarily all 7 pages' worth of examples, but at least a note about it, since high school math cl***es call for such an operation so often
<11> dacicus- so do I floor, ceil or truncate past the hundreds?
<8> loconut: Well, I was answering based on my analytic chemistry info
<8> I'm not sure if that's what you would use in a math clas
