NO IT ****ING IS NOT GARARARAR GREEBL GREEBL.THERE ARE SO MANY PROBLEMS IN TODAYS WORLD THAT WE CAN'T SOLVE BECAUSE OUR SYSTEM OF NUMBERS IS BULL****.
IT WORKS IN THE SHORT RUN BUT WHEN WE START HAVING HUGE FORMULAS THAT TAKE DIFFERENT EQUATIONS WORKED OUT THROUGH MANIPULATING NUMBERS LIKE PI AND STICK THEM ALL TOGETHER IT'S SCREEEWED.
PI SHOULD BE A DEFINITIVE VALUE. BUT IT'S NOT BECAUSE OUR NUMBER SYSTEM SAYS *Girlish prancy voice* Ohhhh you can't make pi an exact value because the numbers go on forever *End of girlish prancy voice*
YOU CAN PROVE THINGS THAT AREN'T TRUE (IN THE MINDS OF PEOPLE THAT THINK IT'S TRUE).
EVERYONE WAS SURE THAT THE WORLD WAS FLAT AS MUCH AS THEY WERE SURE 1+1=2 AND THAT WAS THEREFORE SAID TO BE TRUTH, BUT THEN CHRISTOPHER COLUMBUS PROVED THAT IT IS ROUND AND EVERYONE'S *OPINION* WAS CHANGED.
LAW IS ALSO SOMETHING THOUGHT UP BY HUMANITY BUT JUST BECAUSE IT'S SOMETHING THAT A LOT OF PEOPLE SAY IS TRUE DOESN'T ACTUALLY MAKE IT TRUE.
P.S. Numba system 'aint perfect Grin
our math system is messed up but who would change it?
QuoteYOU CAN PROVE THINGS THAT AREN'T TRUE (IN THE MINDS OF PEOPLE THAT THINK IT'S TRUE).NO YOU CANT. NAME A SINGLE EXAMPLE.
Look at religion. Look at anything that is deemed as the truth, there always will be inconsistencies.
Without rounding up, 0.99~ is equal to one. You see, all integer numbers can be written in two ways, lets take 1 for example:1.00000~0.9999~Em, remember how to turn numbers with infinite periodic decimals into fractions? Code: [Select]0.444444~ = 4/90.323232~ = 32/99Well, do that with 0.9999~Code: [Select]0.9999999~ = 9/9 = 1No need to know and understand the idea of limit, just read the explanation above.
0.444444~ = 4/90.323232~ = 32/99
0.9999999~ = 9/9 = 1
Pi is an irrational number yes, but because of humans way of arranging values like pi into what we know as our number system, it makes them undefinable. It goes on forever. If we had a different number system where we could just say BAM x=pi (That fits in with everything else) then we could make calculations perfect.At the moment we are just going by an inaccurate set of digits that go on forever and therefore we are never going to acheive perfect maths. The same with the .999 = 1 thing. If the number system humans thought up would have been considered more before saying it's perfect then we wouldn't have these problems.
The reason all of our maths is screwed is because the stupid guy that invented our number system made it like it is today, which causes problems with things like .999 and infinity.
This is all leading back to what I said already, if at the beginning when they first thought up the concept of a number system they thought about it a lot more than what they obviously didn't, then we wouldn't have friggin problems like these.
No that's just exploiting the algebraic system to prove something that isn't actually true, there are many other things you can 'prove' using it too, but they aren't accurate. THE NUMBER SYSTEM IS ****ED get a new one earth.
But it's .99999999999, not 1. So techinically, It's .9999999999, not 1, because you didn't say it was 1.
0.333… = 1⁄3is still rounding. Just go with fractions people.
I know people didn't invent pi, I didn't say that. It's the way our number system sets it out like that, which is the cause of humans making the number system like that in the first place.EDIT: Ugh .. ok so like instead of using 1 and 2 and 3 etc. we could have something completely different, not even necessarily in consecutive order. Hmm ... it's a hard concept to grasp because it's almost unimaginable, seeing as it's nothing we've never seen or used. But it would be really weird anywho. Ugh, I can't even be bothered to think about this now... Tongue
There could even be more intelligent beings out there that have 'perfect maths'. Hate saying that cause I know you're going to moan, but they could come here and prove our ideas of maths and science to be bull****.
Why don't we use binary? Be alot simpler imo.
Pi IS defineable. It's most certainly a defined number. A number that is NOT defined is something like 1/0. Just because something can't be expressed as a fraction doesn't mean it's not defined. Also, pi is not this way because of "humans way of arranging values like pi into what we know as our number system," it's that way because that's the way the universe works. People didn't INVENT pi. Pi was DISCOVERED to be the ratio of a circle's circumference to its diameter (or its area to the square of its radius).On topic, the definition of the "..." notation used for 0.999... seems not to be understood. The definition of 0.999... is the limit of the sequence {sum(9/(10^i)) for i from 1 to n} for all natural numbers n. This basically is a precise way of defining the sequence {0.9, 0.99, 0.999, ...}. Every number in that sequence is a real number (a rational number, no less). The limit of this sequence, I'm pretty sure, we can all agree, is 1. Therefore 0.999... = 1.

However, if we do this, then every time you want to say something like "I have one apple," that "one" would be a repeating decimal. Every time you used the number one in calculations, it would be a repeating decimal. All integers as we use them would have to be irrational (I'm fairly certain) in order for pi to be a rational number, by a different definition of numbers.I'll have more on this after I get done studying how we define the real number system based on the rational number system this week in Abstract Algebra.
It's exploiting the system of algebra, if by "exploiting," you mean "using." Show me the inaccuracy in the logic that makes it "exploiting the algebraic system to prove something that isn't actually true." Show me something false you can prove using valid algebra, and I will be inclined to concede to your point.
Wow, that's annoying and weird that when you edited your post, it bumped it below mine, in which I REPLIED to your post. Strange forums
But on to the point, if you're saying that we could use some kind of token number to represent pi, then I have nothing to say but that we already have.
You're basically stating (as far as I can tell) that every number should have a finite decimal representation, or in other words, every real number should be rational. You're claiming that there IS a way to do this. My first response is: Prove it. The burden of proof rests on you, my friend, because the real number system as it is now seems perfectly well defined to me and all the brilliant mathematicians in the world.
My second response is one you won't understand. You are claiming that there does exist a bijection between the rational numbers and the real numbers, a statement which can be and has been proven to be false, by extension of Cantor's proof that there is no bijection from the natural numbers to the interval (0,1), a proof I can duplicate if need be
They are things like 0 = 1, 1 = 2 and some others that I can't remember, say 4 = 12 (That one I don't know how to do, because I just made it up, but it's just an example).
I can't prove it, and I don't intend on trying to, it's just too insanely difficult. It can be accomplished, but not by me, probably by the next Einstein.

.99999999--> will continually get closer to 1, but never reach it. draw a graph of y=1/x to see a visual example.
