  1. What is infinity divided by infinity? - Mathematics Stack Exchange

    Aug 11, 2012 · I know that $\\infty/\\infty$ is not generally defined. However, if we have 2 equal infinities divided by each other, would it be 1? if we have an infinity divided by another half-as-big infinity, for

  2. 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

  3. 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.

  4. 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 …

  5. linear algebra - Basis for an infinite dimensional vector space ...

    Feb 20, 2024 · Usually, on infinite-dimensional vector spaces you want to add more structure (a scalar product for instance) and use more flexible and usable notions of basis (Hilbert basis for instance, …

  6. Can a set be infinite and bounded? - Mathematics Stack Exchange

    Aug 7, 2014 · 'every infinite and bounded part of $\mathbb {R^n}$ admit at least one accumulation point' because for me a set is either bounded so finite or infinite so unbounded. I don't really understand …

  7. probability - How to solve dice problem using infinite series and ...

    Nov 17, 2024 · How to solve dice problem using infinite series and combinations? Ask Question Asked 1 year, 2 months ago Modified 1 year, 2 months ago

  8. linear algebra - Proof that two bases of a vector space have the same ...

    16 Once you have the necessary facts about infinite sets, the argument is very much like that used in the finite-dimensional case.

  9. abstract algebra - Examples of infinite groups such that all their ...

    Nov 28, 2018 · I am in need of examples of infinite groups such that all their respective elements are of finite order.

  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 …
