Homonym: \infty (Eternity)
The symbol "\infty" represents the concept of infinity, which refers to something that is limitless or unbounded. In mathematics, it is often used to describe quantities that grow without bound, such as the value of a function as it approaches a certain point or the size of a set that has no end, like the set of natural numbers 1, 2, 3, ....
Infinity is not a number in the traditional sense; rather, it is an idea that helps mathematicians and scientists understand and work with very large or very small values. It appears in various fields, including calculus, where it is used to describe limits, and in set theory, where it helps categorize different sizes of infinite sets, such as real numbers and integers.
