Let me get this straight. 0.999... is really really really really really really really really really really really really really really really really really really really really close to 1 so we just say it equals 1 but it isn't ACTUALLY 1. right?

 >> Anonymous Tue Jul 24 00:39:54 2018 No.9889083 >>9889074No.> really really really really really really really really really really really really really really really really really really really really closeThis implies that you believe eventually the 9s end. The 9s don't end. It isn't "really close" to 1 -- the 9s don't end at some point leaving a space between the last 9 and 1.0. The 9s never end. It's equivalent to 1.

If they must be repeating, then the number doesn’t ever truly exist, and it is never complete. Yet 1 is complete, so the equality does not hold.
 >> Anonymous Tue Jul 24 02:01:55 2018 No.9889249 0.999... is a convergent infinite sum that converges to 1. While it's true that for any finite n, 9/10 + 9/100 + 9/1000 + ... + 9/10^n is strictly less than 1, the limit of the sum converges to 1.

 >> Anonymous Tue Jul 24 02:14:43 2018 No.9889276 >>9889264Because an asymptotic curve makes sense. 0.999... only makes sense as the limit of a sequence and that limit happens to be 1.
 >> Anonymous Tue Jul 24 02:19:26 2018 No.9889288 >>9889276I see no difference. The vertical asymptote is a limit just as 1 is. Either we say that 0.999... can never equal 1 and that an asymptote is never touched or we say the opposite for both. If a vertical asymptote is at x = 1, how can only one statement be true?
 >> Anonymous Tue Jul 24 02:19:28 2018 No.9889289 >>9889074The problem is that you're thinking of infinite decimal strings as the canonical form of the real numbers. We don't define real numbers as decimals, but using some construction like equivalence classes of Cauchy Sequence or Dedekind Cuts. It can them be shown from there that we can represent reals as infinite decimal strings (0.999... denoting the Cauchy sequence 0.9, 0.99, 0.999, etc for example). This representation is not unique.

Mathematicians “solved” this problem by saying 1/2 + 1/4 + 1/8 converges to 1 or however they wanna word it. The fact is this sum never equals 1, so you cannot, in fact, reach 1 with the above process. How can we still walk from one side of the room to another? Because there is no such thing as an infinitely small distance and even if there were, we humans can obviously not move at such a small distance.

Any smooth movement would consist of infinite moments, and any subset of that would contain infinite moments, ad infinitum. The finite cannot contain the infinite. And an infinitely small distance cannot actually exist, because if it did, and you could measure it, then there would be a smaller distance than that. So if you say that you moved through an infinite amount of distances, how large were those distances? They can’t be infinitely small, but if they were any bigger, then you would have moved an infinite distance.

If I cut an apple in two, it is not one apple cut in two, but now two halves of an apple. There is a fundamental unit for space and time, and all objects are composed of large amounts of these units. A larger apple is said to be one apple, although it’s parts are greater in number than the smaller apple. Anything that can be divided was composed of multiple parts to begin with.

So a number like 1/10^1000 only exists to portray a relationship between two quantities, but it is not a true quantity itself. So if I were to answer your question about what is the smallest fraction, then I would have to know the greatest amount of units that exist in the universe. I believe that number is finite, but no matter, I can conceive that the number is greater. But I can not conceive of an infinite number, so there is no limit to that greatest number, but it can’t be infinite. Only 0 is infinite.

Starting from the first point where the curve meets the line, we can trace the curve backwards, and the gap between it and the asymptote will ever increase until we reach y = 0. We could do this in a finite amount of time, which contradicts the nature of an asymptotic curve. Also, for the graph 1/ 1-x, you’re admitting that the graph can yield a point at x = 1, so we can divide by 0, which is impossible.

You can’t say that it contains an infinite amount of 9’s, only that there is no limit to how many 9’s you can add. At no point will the 9’s ever equal 1. You cannot conceive an infinite process as something that becomes actual; it is never-ending, never complete. A circle cannot have an infinite radius, or it would no longer be a circle. A finite distance can not contain infinite intervals, or it would no longer be finite. If we conceive 0.999.. in the most natural way possible, that is, fractions, then we would realize that as we increase the numerator, we also increase the denominator. At no point does the numerator ever become equal to the denominator. Infinity is a broken concept that is completely misused and causes contradictions and paradoxes. There is no use for this thinking. We can use methods of exhaustion without ever conceiving of a quantity that is infinite.

There exists a city, such that, for every 10^n amount of people, there is a 10^(n-1) amount of people who have brown hair, and 1 person with red hair. As n is unbounded, the amount of people with brown hair is approximated by 0.999...If there are 10 people, then one will have red hair. If there are 100, then 1 will have red hair. No matter what the population is, there will always be one person with red hair.

 >> Anonymous Tue Jul 24 13:23:54 2018 No.9890162 >>9890134The next number after 1 is 2. The number after 0 is 1. All “numbers” between 0 and 1 are relationships between a part and a whole. So the smallest fraction after 1 is simply dependent on the denominator, since the numerator is always 1. But there is no limit to how large the number can be, so there is no limit to how small the fraction can be. Since there will always be a 1 in the numerator, the part never equals 0. Similarly, with 0.999... there will always be a difference of 1 between the numerator and the denominator. Write out the differences as you increase n: 1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1......How does this ever magically become 0?But all this is only true abstractly. It has not been proven that there exist an infinite amount of units in the universe, so there could be a limit to how small a single unit could be to the total amount of units in reality.

Although an infinite set is illogical and inconceivable, even then, every natural number could form a relation with every other natural in the set, which would be just as large as the list of numbers themselves. All rational numbers with the numerator 1 would already be equal to the set of natural numbers, and we haven’t used 2 as a numerator, so it is clear that the set of rationals will always be greater.

Why play with this cute notation of infinity when it makes no intuitive sense and has no application? It is true when we say that the limit of (10^n - 1) / (10^n -1) equals 1 but that doesn’t mean it will ever equal 1. It is unbound in its numerator and denominator values but bound in its fractional value, that is, the relationship will never equal 1. Magically transforming the number into an “infinite” one does not make the problem go away, and is hardly intuitive.

But their arguments can be easily pulled apart so they aren't really convincing the masses. A limit is not an equality of a function over any amount of iterations, while convergence/divergence are also feasibly invalidated by the disingenuous attempt to exclaim that convergence is useful towards finding a value, yet divergence invokes negatory nullifying claims that a value tending towards infinity can't be explicitly useful; where the irony lays on the fact convergence is just the literal same process as divergence except with a real number limit. Ultimately, even withstanding faith in convergence, its retarded to say $\sum_{n=1}^{\infty} \frac{9}{10^n} = 1$ in lieu of the more honest and accurate statement that $\sum_{n=1}^{\infty} \frac{9}{10^n} = 0.\bar{9}$A limit can be a real number, and if you're trying to say the limit can't be 0.999..., you're just admitting that 0.999... is not a real number.mathematicians are actually conditioned to be retarded through their bastardized curriculum they call an education, and I do not envy them.

So there is no inherent easily understood intent derived from $\sum_{n=1}^{\infty} \frac{9}{10^n}$ in how it is supposed to equal 1. Its just repeating 9's. Overlines and ellipses do not mean the entirety of an infinite process has been concatenated, cause that would aim to treat infinity like a real, finite number. The symbology only exclaims a repeated pattern exists, with absolutely no indication for how many significant digits are required for an equation. Like how $\pi$ means "pi", but not "3.14159" or any fixed amount of digits.Just as we can say 3.14159 is a good approximation for pi, we can also say thay 0.99999 is a good approximation for 0.999..., and just as any greater extension of digits in pi does not arbitrarily increment previous digits (3.14, 3.141, 3.1415, 3.14159, ...), so does any greater extension of digits in 0.999... not arbitrarily increment previous digits (0.9, 0.99, 0.999, 0.9999, ...).Therefore 0.999... is a unique identity for a unique number that is not 1, but this number is not intelligenty crafted outside of $\sum_{n=1}^{\infty} \frac{9}{10^n}$

You could just as easily say that the sum 10^n converges to an arbitrarily large real finite number in some n amount of iterations. To diverge and converge are the same mechanical process. Converging to 1 on 9/10^n is no more or less meaningful than diverging to infinity with 10^n, and there are infinitely many ways to either converge to 1 (or ANY given number) and also diverge to infinity.x/(x+1)^n converges to 1 for infinitely many integer x's, and x^n diverges to infinity for infinitely many integer x's too.You change the numberline when you have a limit. If 1 is the limit, that 1 then becomes the equivalent of infinity on an unresricted numberline. You will have as many divisions above 0 you want, but you will never increment to 1 on this limited numberline, no more than you could increment to infinity on an unrestricted numberline.Convergence and divergence are the same exact identical method and your brainwashing runs deep if you think I'm lying to you or don't know what I'm talking about.
 >> Anonymous Thu Jul 26 02:54:59 2018 No.9893775 >>9893742Convergence and Divergence are via the function of a limit. They are the same process, but with a different parameter. If the limit is any real number, its considered convergence. If the limit is infinity, its considered divergence. This is the problem though, since converging on infinity is explicitly just as meaningful as diverging to infinity based on the definition of infinity itself. Its not a bad thing to "diverge" to infinity, else it would be a bad thing to "converge" to any real number. Its not a good thing to "converge" to any real number, else it would be a good thing to "diverge" to infinity. The ultimate value of the parent function monitoring convergence and divergence relies heavily and explicitly on infinity being well defined, which it isn't, but even if it were, means the function itself is not necessary or beneficial towards acquiring any further truthful answer. Instead of revealing unknown information in an equation, it instead only acts to transform the equation into an alternate rendering yet fundamentally leaving the equation unchanged. Its not really a valid maths thing. Wir können auf Deutsch sprechen, aber dies ändern die Problem nicht. Es ist nür übersetzung und nie änderung. Die Problem kommt von ob sie kennst Deutsch, just as your problem comes from if you think you can trip anyone up with unnecessary and unhelpful math terminology that doesn't aim to solve a problem any better than it was already solved more simply before.

Deal with it.A number like [0.000...1] shouldn't bother anyone unless they misunderstand the applications of math or the meaning behind the symbology of 'repeating'. Any irrational decimal will be used up to a finite, real point. [0.999...] doesn't mean "infinite nines"; it means "as many real nines as you need". Doing any math with this value will always come to a finite point.So the ellipses in [0.000...1] doesn't mean something to come after the infinite. It means there are as many real 0's as needed, followed by a 1.Infinity is not well defined. Infinity is not meant to be used. At best, it is not considered an actual number, and at worst it pretends to be "the greatest number, greater than all other", which in that very definition makes it finite because it is a ceiling that can't be surpassed, much as there is a finite distance between your floor and the ceiling above. Infinity is nonsense.
