You can't have summed an infinite amount of numbers, however, for that implies an end occurred, and an end defines it as finite.Infinity is legitamately the dumbest shit ever conceived, and worse yet it has no practical usage in any virtue of engineering.

You want to say $0.\bar{3} = \frac{1}{3}$ because you believe the bar means "infinite threes", even though it is well established that there is no such thing as an infinite amount of something because infinity is not a number. The bar over the three doesnt mean infinite. It means there is a pattern of ongoing repetition. 1/3 > 0.31/3 > 0.331/3 > 0.333You can continue extending more threes into the decimal in a repeating, ongoing pattern, and 1/3 will always be greater than that decimal value.

You can count to gdajllllop on the numberline. It comes after any number you count to but then stop on.

You can only say there are "infinitely countable" 9's, or you could just as easily say there are "a lot" of 9's, both phrases mean the same vague, brainlet bullshit of lazy concatenation and inadequate description.

You can only compare how many 9's there actually may be if you assume to count them, and if you assume to count them there must always be a real number amount of 9's as counting to infinity is not an achievable action. 0.999... is only truthfully as good as 0.(1000 9's) or 0.(1 million 9's), or, just as vague as you like to be you could claim 0.(an arbitrarily large real number amount of 9's)

No, I don't believe it can, butB) Can you refer to the concept of having an infinitely long running process in one location, like a wheel that keeps spinning forever, and also refer to a separate finitely long process in another location, like a different wheel that spins for 1 minute and then stops? Yes, I believe you can.And this is pretty much how an idea like ω + 1 is handled in the systems that use that sort of idea. You treat it like having two collections or two objects.

 >> Anonymous Sat Feb 24 17:23:40 2018 No.9541809 How would a limit be formalized on a computer?Computers contain only finite data, but a computation can either be finite or infinite. While computations of a limit are infinite, it will never provide a useful result. Limits can be approximated by taking an intermediate result after an arbitrary amount of computation, but the process does not preserve the concept of a limit.From my own meditation, a limit is a function that takes two arguments, a starting point, and an inductive process, and computes an object that represents a number. The starting point may come in handy for computing limits for induction on rational numbers, or more complicated data types.For example, let $S$ be the successor function on natural numbers that takes a number and returns its successor, then $limit(0,S)=+\infty$, as would $limit(S(0), S)=+\infty$, and so on and so forth. Note that this limit is only represented symbolically by $+\infty$, its actual representation would be some sort of data structure.Define a sequence $s$ to be any function that takes one natural number as its arguments. One can also define an inductive process computing the next element of $s$ from the previously defined inductive process $S$ and $s$ itself.$limit(s(0), inductive\_process(S,s))=lim_{n\rightarrow +\infty} s(n)$Similarly, limits of a function $f$ can be defined by composing $f$ with a sequences converging to $x_0$ to define a new sequence converging to $f(x_0)$.If anyone has relevant literature, I would be more than happy to take reading recommendations.

If you assume there is nothing inside a black hole then why do you think a black hole could exist?There is obviously a substantial amount of something in a black hole else it would evaporate instantly, and just cause you cant interact with what is inside doesn't mean it isn't there. If you want to assume "..." means infinite, and that an infinite value can exist to have been knowably counted as such, you're dumb - but if you want to then extend that to no value can come after an infinite amount, you're super dumb. If you never travel to the south pole, that must mean it doesn't exist by your logic, and that there could be nothing beyond the south pole if you continued walking on the same path as you approached it.

No. It's because the process of division is defined by a multiplication of the inverse, i.e. a/b = a*b^(-1), where b^(-1) is the number such that b*b^(-1) = 1. In the axiomatic definition of an inverse in any field, it's given that 0 does not possess an inverse (unless we're talking about the degenerate singleton field over the set {0}, in which case 0=1). But in the field of real numbers (R,+,•), 0 is an element of the reals and does not possess an inverse, so n*0^(-1) is not defined.

I could take each type, enumerate the number of them in the room, add all these together, and get the total number of animals. You just picked a category with many subtypes to obscure things. Counting the total number of animals is no different when there are 0 of certain types than if I had 2 of each type marching side by side. either way I can count them by taking the number of each type and adding them.

Some would say that every natural number has a successor, but you can't have a set of all the natural numbers. Other's may say that you can express arbitrarily large numbers symbolically, but their "existence" is not a binary quality that suddenly stops after a greatest number.
 >> Anonymous Sun Feb 25 00:59:50 2018 No.9542686 >>9542520Vector is reasonably well defined in simple words. google it if you think i somehow used it incorrectly. The direction is "more and more" or "unending". If you want to describe a property of the repeating 3's in 1/3 decimal as "infinite", you are saying that the 3's never stop. If the 3's never stop, there is no reason to believe there will ever be a sufficient enough amount of 3's to finitely equate "1/3", so 1/3 must always be greater than 0.333... You can then obey normal finiteness in assuming that an arbitrary invocation of the number $0.\bar{3}$ can only have an arbatrarily large real number amount of countable 3's towards either providing a decimal accuracy requirement and therefore a definite end to the 3's, like an 8 digit calculator may only show 0.(seven 3's), or you can presume with arbitrary decimal accuracy that a repeating decimal lacks a definite element of accuracy whereby 1/3 need not necessarily be greater than 0.333..., but it must only approximate to 0.333... without actually equaling 0.333... as $\frac{1}{3} \approx 0.\bar{3}$, providing the understanding that there exists a margin of error. This further accomodates how $\frac{1}{3} × 3 = 1$ but $0.\bar{3} × 3 = 0.\bar{9}$, as the decimal values have lost an exactness element in translation. It also accomdates that because there exists no infinite number amount, a set must also be bounded by an arbatrarily large real number amount, which taken literally or even figuratively to describe the group of individual digits in a repeating decimal, provides that arithmetic performed on a set will also abide by finiteness, which ultimately disproves obviously flawed garbage nonsense like riemann zeta and ramanujan which otherwise required disingenuous "shifting" on "infinite sets" which cannot be similarly applied to finite sets. It also provides better analogies to zeno's paradoxes to make certain an infinite sum of 1/2^n cannot really reach 1.

Septillionth is enough decimal accuracy to describe even once in a universal lifetime events such as that if every millisecond since the big bang were randomly assigned a number where the number assigned wasn't taken out of the pool of remaining numbers, there is less than $\frac{1}{1,000,000,000,000,000,000,000,000}$ probabilty any millsecond would have received the same random number as another millisecond. Real upper bound? No reason to assume its necessary. Practical global upper bound? Septillion, maybe? Practical local upper bound? Most any digital media you've ever seen has gotten far enough with only 15 decimals of accuracy. Most cryptography has gotten far enough with only 256 digits. "Arbatrarily large" is well below the classical misinterpretation of infinity, yet even "arbatrarily large" is significantly larger than any yet utilized precision requirement. The classical "value" of infinity is honestly so fucking big that it could never matter, when most precision can be solved or described with only 15 significant digits.

Scalars are often taken to be real numbers, but there are also vector spaces with scalar multiplication by complex numbers, rational numbers, or generally any field. The operations of vector addition and scalar multiplication must satisfy certain requirements, called axioms, listed below.>Euclidean vectors are an example of a vector space. They represent physical quantities such as forces: any two forces (of the same type) can be added to yield a third, and the multiplication of a force vector by a real multiplier is another force vector. In the same vein, but in a more geometric sense, vectors representing displacements in the plane or in three-dimensional space also form vector spaces. Vectors in vector spaces do not necessarily have to be arrow-like objects as they appear in the mentioned examples: vectors are regarded as abstract mathematical objects with particular properties, which in some cases can be visualized as arrows.>Vector spaces are the subject of linear algebra and are well characterized by their dimension, which, roughly speaking, specifies the number of independent directions in the space. Infinite-dimensional vector spaces arise naturally in mathematical analysis, as function spaces, whose vectors are functions. These vector spaces are generally endowed with additional structure, which may be a topology, allowing the consideration of issues of proximity and continuity. Among these topologies, those that are defined by a norm or inner product are more commonly used, as having a notion of distance between two vectors. This is particularly the case of Banach spaces and Hilbert spaces, which are fundamental in mathematical analysis.

The modern, more abstract treatment, first formulated by Giuseppe Peano in 1888, encompasses more general objects than Euclidean space, but much of the theory can be seen as an extension of classical geometric ideas like lines, planes and their higher-dimensional analogs.>Today, vector spaces are applied throughout mathematics, science and engineering. They are the appropriate linear-algebraic notion to deal with systems of linear equations. They offer a framework for Fourier expansion, which is employed in image compression routines, and they provide an environment that can be used for solution techniques for partial differential equations. Furthermore, vector spaces furnish an abstract, coordinate-free way of dealing with geometrical and physical objects such as tensors. This in turn allows the examination of local properties of manifolds by linearization techniques. Vector spaces may be generalized in several ways, leading to more advanced notions in geometry and abstract algebra.

For there is found a greater and a less degree of goodness, truth, nobility, and the like. But more or less are terms spoken of various things as they approach in diverse ways toward something that is the greatest, just as in the case of hotter (more hot) that approaches nearer the greatest heat. In the hierarchy of complexity one might find a worm lower down, a dog higher, and a human higher than that. There exists therefore something that is the truest, most complex, best, and most noble, and in consequence, the greatest being. For what are the greatest truths are the greatest beings, as is said in the Metaphysics Bk. II. 2. What moreover is the greatest in its way, in another way is the cause of all things of its own kind (or genus); thus fire, which is the greatest heat, is the cause of all heat, as is said in the same book (cf. Plato and Aristotle). Therefore there exists something that is the limit of the existence of all reals and of the goodness and of every perfection whatsoever—and this we call Infinity.

Do you understand?Your concept of the number "0.333..." lacks meaning and implies beyond it's means. The repetition in a repeating decimal doesn't mean an infinite value amount has been counted explicitly because an infinite value cannot be counted; it only means that there are more repetitions. You are not invoking any sensible finiteness and therefore not invoking any real sense of accuracy by simply providing the number $0.\bar{3}$, so you cannot hope to extract finite answers from equations involving it. You ask what number could exist between 0.333... and 1/3, and the clear and obvious answer is a number 0.333... with one more 3, in the very least. I ask you what number could exist between 0.9 and 1, and you answer 0.9 with one more 9, in the very least.Do you understand?What you mean to say when you say 1/3 = 0.333... is really $\frac{1}{3} = 0.\bar{3}_{\frac{1}{3}}$ taken arbitrarily, or $\frac{1}{3} = 0.\bar{3}_{r.(n-1)}$ taken finitely, where n is your decimal accuracy requirement inclusive of a rounding buffer.The former allows you to properly use arithmetic in $0.\bar{3}_{\frac{1}{3}} × 3 = 0.\bar{9}_{\frac{3}{3}} = 0.\bar{9}_{1}$ where the whole 1 carries over and properly sums 1.0 in totality.
