Question from Divyansh: Is infinite a number? If yes why as i think that numbers are used for counting but infinite is undeterminable? |
Hi,
If you are thinking about the infinity we sometimes see in calculus denoted $\infty$ then it is not a number. This is an idealized point placed at the positive end of the number line. There is a similar point, $-\infty$ at the negative end. These are handy points that help in explaining some concepts in calculus ut they are not numbers.
