They are relative to each other, in a fixed manner. That's the whole basis of mathematics as a system that works the same today as it does tomorrow.
If a number of some amount changes for whatever purpose, it is represented with different notation.
Remember .33... has an infinite amount of digits in representing what it does, which happens to be a FINITE number/amount.
Every single finite number can be represented in the decimal system with an infinite amount of digits. That does not change the fact that the actual amount is and remains finite. Some finite numbers cannot be represented with a finite number of digits.Last edited by Duckenheimer; 02-01-2009 at 08:34 PM.

I know it is a number of infinitely repeating digits that represents the amount.
The AMOUNT of something actually being represented, on the other hand, is FINITE, like I proved.
What I said:
"People are getting confused because they are thinking the amount being represented is actually infinite"
What you said:
"That's because it it."
No it isn't. The digits used are infinite. The amount being represented isn't, like I just proved. Strong failure on reading comprehension indeed.
STRONG denial in this thread. Fascinating psychologically though.Interested in investing in militarizing poultry? Based in our Southernmost continent, no local taxes, no laws to worry about, guaranteed return! PM for further details

My professor wrote a great book on Real Analysis that also deals with multivariable/complex analysis: http://www.math.binghamton.edu/denni...f07/EleAna.pdf

"That's because it it."
It seems like you are saying "that's because it is" (I assume you meant "is"), ie. saying the amount being represented is actually infinite.
I do not understand how my reading is at fault here, because you seem to be disagreeing, and I cannot comprehend reading this in a way in which you are agreeing with my statement. Care to clarify?Last edited by Duckenheimer; 02-01-2009 at 08:46 PM.

NP. After you finish that, take a look at Walter Rudin's Principles of Mathematical Analysis. It's an entry-level grad / advanced undergrad text covering nearly everything you need to know about late Analysis. Next step would be Functional Analysis (also by Rudin) which is the holy grail of Analysis books. Haven't touched it yet, but I'm planning on it shortly.

hai guys I just bought a 1 pound pie for me and 2 of my buds. I want to divide it exactly equally between the three of us with my new found computer-aided laser guide pie cutter to cut perfectly accurately, atomic weight scale to make sure that the slices are equal, and electron microscope to make sure no crumbs are lost. However, I have recently been informed by Klippymitch and Pad that regardless of how hard I try, it is impossible to divide the pie into thirds, because there is no such thing in the real world as 1/3 of 1! What am I supposed to do?!

It's kind of like life. Our lives don't really change until those moments where we were pushed, and that's where we grow the most and our life becomes more rich. If you don't push your body beyond what it's comfortable with, nothing changes."

The point is that you cannot divide the pizza into precisely three EQUAL parts. Even if you have to take the decimal 50 trillion places out, it will eventually become a finite number. We're not talking about math, we're talking about physics. The laws of the universe do not allow us to divide any object as precisely as you can in a math formula.
You are defending the ".99 repeating" is equal to 1 equation on the basis of a mathematical fact. We're not talking about math...your defense for the equation cannot be, "It is fact because it is fact," once we're no longer having a mathematical discussion. The laws of math do not apply outside the world of math. It is no different than any other language. A window is a "window"...but in Italy, it's a "finestra." The "laws" change. The fact that Math is universally accepted by all cultures, as opposed to written/spoken languages, does not mean that it applies to all of the universe.
Theoretical math allows us to be more precise than we can ever hope to be in practice. Even with technology exponentially improving, we can never hope to achieve an infinite measurement in the world."My only enemy is time." - Charlie Chaplin

Again, you are distinguishing between ".99 repeating" and any other repeating number. Is ".33 repeating" not infinite? How about ".44 repeating"? You are making an exception for ".99 repeating" based soley on a mathematical proof that does not apply to anything other than math.
Read that last sentence again...because it's tough to imagine a world without math. Math is everywhere. What you must understand is that math is not inherent to the universe, it was applied to the universe."My only enemy is time." - Charlie Chaplin
