  1. Uncountable vs Countable Infinity - Mathematics Stack Exchange

    My friend and I were discussing infinity and stuff about it and ran into some disagreements regarding countable and uncountable infinity. As far as I understand, the list of all natural numbers is

  2. Basis for infinite dimensional vector space definition

    Feb 4, 2023 · In some of these infinite-dimensional vector spaces, when they're normed, there may be Schauder Bases , where we have infinite sums, which require a notion of convergence.

  3. I have learned that 1/0 is infinity, why isn't it minus infinity?

    An infinite number? Kind of, because I can keep going around infinitely. However, I never actually give away that sweet. This is why people say that 1 / 0 "tends to" infinity - we can't really use infinity as a …

  7. Why does an infinite limit not exist? - Mathematics Stack Exchange

    Mar 25, 2023 · The term "infinite limit" is actually an oxymoron, like "jumbo shrimp" or "unbiased opinion". True limits are finite. However, it is okay to write down "lim f (x) = infinity" or "lim g (x) = …

  8. Riemann sum on infinite interval - Mathematics Stack Exchange

    Aug 12, 2015 · It is well known that in the case of a finite interval $[0,1]$ with a partition of equal size $1/n$, we have: $$\\lim_{n\\rightarrow \\infty} \\frac{1}{n}\\sum_{k=0 ...

  9. Infinite Series $\\sum 1/(n(n+1))$ - Mathematics Stack Exchange

    May 10, 2021 · Write out a few terms of the series. You should see a pattern! But first consider the finite series: $$\sum\limits_ {n=1}^ {m}\left (\frac {1} {n}-\frac {1} {n+1 ...

  10. How was Zeno's paradox solved using the limits of infinite series?

    +1 that's a great answer. Especially for the last point: I agree that Zeno's paradox is basically an example of how there can be infinitely many intervals in a finite period of time. I didn't know that there …
