  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. 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 …

  4. 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, …

  5. infinity - Infinite averages - Mathematics Stack Exchange

    Apr 28, 2015 · You need to endow your infinite set with a measure such that the whole space has measure $1$ and then integrate (and hope that your function is measurable to begin with). For finite …

  7. real analysis - Why set of natural numbers is infinite, while each ...

    In his book Analysis Vol. 1, author Terence Tao argues that while each natural number is finite, the set of natural numbers is infinite (though has not defined what infinite means yet). Using Peano...

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

  10. 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 …
