  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. What exactly is infinity? - Mathematics Stack Exchange

    Definition: Infinity refers to something without any limit, and is a concept relevant in a number of fields, predominantly mathematics and physics. The English word infinity derives from Latin infinitas, which …

  3. Types of infinity - Mathematics Stack Exchange

    Oct 28, 2015 · I understand that there are different types of infinity: one can (even intuitively) understand that the infinity of the reals is different from the infinity of the natural numbers. Or that the infi...

  4. Can I subtract infinity from infinity? - Mathematics Stack Exchange

    Apr 28, 2016 · Can this interpretation ("subtract one infinity from another infinite quantity, that is twice large as the previous infinity") help us with things like limn→∞(1 + x/n)n, lim n → ∞ (1 + x / n) n, or is …

  5. Why is $\\infty \\cdot 0$ not clearly equal to $0$?

    Mar 25, 2011 · You never get to the infinity by repeating this process. Limit means that you approach the infinity but never actually get to it because it's not a number and cannot be reached. The expression …

  6. One divided by Infinity? - Mathematics Stack Exchange

    Similarly, the reals and the complex numbers each exclude infinity, so arithmetic isn't defined for it. You can extend those sets to include infinity - but then you have to extend the definition of the arithmetic …

  7. definition - Is infinity a number? - Mathematics Stack Exchange

    For infinity, that doesn't work; under any reasonable interpretation, 1 + ∞ = 2 + ∞ 1 + ∞ = 2 + ∞, but 1 ≠ 2 1 ≠ 2. So while for some purposes it is useful to treat infinity as if it were a number, it is important to …

  8. limits - Infinity divided by infinity - Mathematics Stack Exchange

    Dec 25, 2017 · In the process of investigating a limit, we know that both the numerator and denominator are going to infinity.. but we dont know the behaviour of each dynamics.

  9. philosophy - How big is infinity? - Mathematics Stack Exchange

    Jun 17, 2014 · This "infinity" admits multiplication by real numbers, so that for example, the rate of change at 0 0 of the function that is 3.2 3.2 times this function, is just 3.2 3.2 times the "infinity" that …

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

    This resolves your problem because it shows that 1 ϵ 1 ϵ will be positive infinity or infinite infinity depending on the sign of the original infinitesimal, while division by zero is still undefined. This …
