Wow thanks for the input (lol... comp sci jokes are sad ) but yah, I havent fully gotten parseing strings and such... but I'll work on it. The thing is, when you get a user to enter say a string, isn't it broken up at every space? I know theres some kind of cin.getline or something like that in c++ that can handle spaces... What would that be? (is it cin.getline() ?)

How do I go about finding out how much bandwith my connection has? I always have sites (usually streaming media sites) that ask how fast my connection is (in kbits). I have no clue and would like to find out. preferably if there is a site that does this (accurately), that'd be great! side note - didn't know where exactly this fits in so I put it in comp sci

I believe all minors attending public schooling should have mandatory immunity shots. despite this I was never vaccinated in grade 9 for turberculosis (I think that's what it was). Only 'cause I forgot to hand in my form lol.

hello all I was wondering if anyone knows of some interesting programs involved with evolution. I have one on my computer called Avida although they seem to stop work on it awhile ago. Any others that people know of, please post! btw the avida link is here

well I'm pretty sure in equations like w = fdcosx it's given that its dot multiply... or at least that'd make sense

hey all! I currently use GraphCalc v4.0.1 It supports 3D graphing, and is a pretty interesting program, however I was wondering if there are any graphing programs that support relational graphs? I find having to create graphs as functions only a bit restrictive. an example is z^2 = x^2 + y^2 (a sphere) I can't make one with my current graphing calc because it doesnt do non-function graphing. If anyone knows of a graphing calculator that can do what I'm proposing, please post a link. BTW - It'd have to be a free one too lol Thanks in Advance!

more generally and more complicated lol

yah lol that was it

meh, I think they should do it, however since the humanzee is not fully human he wouldn't be subject to fully human rights. So they'd be creating a second class citizen. This is what I think needs to be decided as ethical or unethical but as to what my opinion is... I wanna see a humanzee! lol, It'd be amazing if it could speak (or at least communicate far beyond ordinary chimpanzee's using sign language). It could be our first conversation with another creature that is intelligent enough for speech, their outlook on life would be so radically different from ours, it'd be amazing I think. btw, was spaceman banned 'cause of the flaming war? lol

When people think of the 'classical' singularity they probably think of (or at least I think of) spacetime looking like this: Thats an image of the graph [math]z(y,x) = \frac{10}{x^2 + y^2}[/math]. Sorta reminds me of that halloween episode of the simpsons where homer found that portal to another dimension behind his bookcase and it turned him 3D lol. I think he dropped a bowling ball and it made a black hole (???) lol. Anyways, most people don't think of singularities as some mathematical stupidity in a theory, more think of it as an actual thing.

first, I thought that two vectors multiplied give a scalar value. And whats with this 'dot product', I heard my friend who's in advanced physics saying how regular multiplication and dot multiplication is totally different...

heh, now imagine the surface area of the metal sheet is increasing at some rate, and you have to find out how fast the sides of the squares are increasing (given that they're always cut to get maximum volume). damn related rates lol.

ha holy crap, whats with all the greek letters :-s lol, but yah, derivatives are pretty easy when you get what they mean. When you first learn them you have to use the limit definition to get them (which is a pain), eventually though you learn the shortcut: [math] f(x) = ax^n[/math] [math] f'(x) = (a*n)x^{n-1}[/math] So say you want the derivative of 2x^3. Times the multiplier (2) by 3, take away one from the power and voila! 6x^2 is your derivative. It'd take half a page of work to do it using the limit definition

Unless the matter your speaking about is anti-matter, there would be no photons (or in this case anti-photons) to be emitted as "dark light". Darkness is just the absense of photons being relfected to your eye from that direction. So as 5614 said, it'd just be a shadow lol.

ok ok, now if I knew that [math]d = \sqrt{c^2 + h^2 + a^2}[/math] I would've been able to do the problem... why does d = that? like I said in the original post, I knew that when the helicopter hovered at 0 that [math]d = \sqrt{c^2 + a^2}[/math], I did not know that that was because h^2 is included and since its 0 it's absent...

Thread #38, didn't direct quote it had to re-edit it later and put in quotes from what keano said

I hate how people feel that wikipedia is not a trust-worthy source of information...

I think that (one of) the main arguments of the not-equal-to-oners (lol) is that infinity is not a number. Well, in a physical universe you can't have infinite of anything, it just doesn't work. However, like Tom Mattson said, mathematics is not dependent on the physical universe it's just a tool. But besides that, if .999... does not equal one because it can't progress infinitley then its not a number at all, equal to one, or equal to anything for that matter.

Right now in calculus we're doing related rates, specifically to do with triangles and the useage of Pythagorean Theorem. The problem goes like this: A police helicopter is flying north at 60km/h at a constant altitude of 1 km. On the highway below, a car is travelling east at 45 km/h. When the chopper passes over the highway, the car is 2 km west of the point directly below it. At this moment, how fast is the distance between the car and the chopper changing? Is this distance increasing or decreasing? Explain. Now the answer they give in the back is 40.25 km/h and they say it's decreasing. I figured this out so far with c being the distance the car travels down the highway, h being the distance the helicopter travels along its northerly path and d is the distance between the two and t as time: [math]\frac{dc}{dt} = 45 \mbox{ km/h}[/math] [math]\frac{dh}{dt} = 60 \mbox{ km/h}[/math] What I need to find out is [math]\frac{dd}{dt}[/math]. To get a better feel of what I was doing I drew a diagram in my note book (which I recreated in paint brush and is attached to this thread). I was thinking that [math]d = \sqrt{c^2 + a^2}[/math] (a is the altitude which is the constant of 1 km) but that only works when the helicopter is hovering over the point where the cars path and the helicopters path intersect. If anyone could help me out with this it'd be appreciated. BTW it apparently took my Calc teacher 12 hours to get this lol.

well when I joined an online game called SFGC, I made my first username Canada, then I eventually decided to have a real name (lol) so I changed it to ArmyOfTheSquirrels. When that got old I merged them into Canada[AotS]. Used that name for pretty much every online thing I do now. Or at least something[AotS] lol. (BTW, couldn't use the square brackets here lol)

That "Ugly Plastic Lizard" is godzilla, he could kick spaceghost ass any day lol (it is godzilla, right? lol)

the creationist, they have their stakes and matches ready at all times

I found the coolest calculator on this site: http://www.stardestroyer.net/Empire/Science/Relativity.html If I was travelling at 299,999,999 m/s my relativistic mass would be 820,579 kg (usually 70) and I'd be getting older .000082 as fast as people on earth. try it out lol

lol so confusing... some kind of diagram would be helpful
