6 hours ago - The infinity symbol (∞) is a mathematical symbol representing the concept of infinity. This symbol is also called a lemniscate, after the lemniscate curves of a similar shape studied in algebraic geometry, or "lazy eight", in the terminology of livestock branding.

Does the Infinity Symbol (∞) have any meaning on its own?
Infinity (like most symbols in math) has many different meanings, depending on context. If you look up the definition of "limit at infinity" or "limit is equal to infinity" in a real-analysis textbook, you'll usually see that it is treated differently from 'regular' limits, since that ∞ isn't actually a real-number. For example, you might see something like the following as the definition of a limit: The notation L = lim f(x) as x goes to c means that for any ε, there exists a δ such that for all u where |u - x| < δ, |f(u) - L| < ε. This definition gives meaning to things like "1 = lim sin(x) / x as x goes to 0". However, it doesn't give meaning to the notion "0 = lim 1/x as x goes to ∞", nor "∞ = lim 1/x2 as x goes to 0", since conditions like |f(u) - ∞| < ε or |∞ - x| < δ are not well-defined. Instead, you'll also see some additional definitions: The notation ∞ = lim f(x) as x goes to c means that for any N, there exists a δ such that for all u where |u - x| < δ, f(u) > N. The notation L = lim f(x) as x goes to ∞ means that for any ε, there exist a N such that for all u where u > N, |f(u) - L| < ε Sometimes these multiple definitions can be unified using, for example, the extended real numbers . This saves some writing by generalizing the |a - b| < c notion of "distance" to also work on ±∞. However, this is basically just a notational convenience -- you have to be wary of using the extended-real-numbers, because most of the properties that you take for granted of real numbers don't necessarily apply to the extended reals. For example, if you have real numbers obeying x = y + c, you also know that x - c = y. However, if any of these can be "±∞", the first equation doesn't necessarily make the second one true (For example, ∞ = 1 + ∞ is true when those symbols indicate operations on extended real numbers, but ∞ - ∞ = 1 is not true). Infinity has many other uses in mathematics, beyond limits, but it's where you'll probably come across it first. More involved uses of infinities have to distinguish between different kinds of infinities (such as with cardinalities and ordinalities) -- but that's a topic for another day. More on reddit.com

The infinity symbol in math represents the concept of infinity. For example, the symbol is used in the notation of a limit to denote that the variable grows arbitrarily large, rather than literally meaning an infinite value.

Infinity Symbol ∞
The infinity symbol (∞) represents a line that never ends. The common sign for infinity, ∞, was first time used by Wallis in the mid 1650s. He also introduced 1/∞ for an infinitesimal which is so small that it can’t be measured.

For instance, in the 1700s the infinity symbol began appearing on the Tarot card known as the Juggler or the Magus.

r/learnmath on Reddit: Does the Infinity Symbol (∞) have any meaning on its own?
March 15, 2020 -
Sometimes when we write limits, we say that the limit = ∞. Does that symbol have any sort of meaning on its own, just like 1 and 2 have their own meanings, and so we say that the limit is whatever that symbol represents? Or is the ∞ symbol nonsensical outside of the context of limits like that (because we define the meaning of the expression as a whole?) If its something like the former, does that mean we can substitute the limit expression into areas of math where ∞ is used, just like we can substitute normal limits into arithmetic and treat them as the numbers they equal?
It would be weird to me to use the equal sign if we don't actually mean "equal" (like we do in 1 + 1 = 2).

No symbol has any meaning "on its own." The symbols '1' and '2' have defined meanings. They only seem God-given because you were taught them at an early age.
