The Mathematical Symbol "Reversed Tilde Equals (⋍)"

The "Reversed Tilde Equals" Symbol (⋍)

The ⋍ symbol, known as the "Reversed Tilde Equals", is used within the realm of mathematics to denote a particular kind of equivalence or similarity. Unlike the regular "Reversed Tilde" symbol, this one has an equals sign superimposed on the reversed tilde, adding a layer of emphasis or specificity to the relation it describes.

Usage of ⋍

Just like the ∽ symbol, the Reversed Tilde Equals is employed to highlight relations resembling standard equality. However, the addition of the equals sign generally implies a stronger or more defined form of similarity or equivalence.

Example 1: Strong Similarity

Given the context, when using the expression \( A ⋍ B \), it implies that A and B are not only similar but also share additional properties or characteristics that make their relationship even more intertwined or equivalent in a particular sense.

Significance in Different Mathematical Fields

The ⋍ symbol finds its place in several mathematical domains:

  • Algebra: In algebraic structures or relations, the Reversed Tilde Equals can be used to describe a heightened form of equivalence, which might consider more attributes than the regular ∽ symbol.
  • Topology: Within topological studies, the symbol can sometimes represent a stronger form of homeomorphic or topological equivalences.
  • General Mathematics: In broader contexts, ⋍ can serve to denote a more rigorous or defined form of similarity, especially when the difference between ∽ and actual equality needs a more distinct representation.

In summary, the ⋍ symbol provides a nuanced way for mathematicians to express specific kinds of relationships, particularly when there's a need to distinguish between general similarity and a more refined or rigorous form of similarity or equivalence.

How To Insert the ⋍ Symbol

(Method 1) Copy and paste the symbol.

The easiest way to get the ⋍ symbol is to copy and paste it into your document.

Bear in mind that this is a UTF-8 encoded character. It must be encoded as UTF-8 at all stages (copying, replacing, editing, pasting), otherwise it will render as random characters or the dreaded �.

(Method 2) Use the "Alt Code."

If you have a keyboard with a numeric pad, you can use this method. Simply hold down the Alt key and type 8909. When you lift the Alt key, the symbol appears. ("Num Lock" must be on.)

(Method 3) Use the HTML Decimal Code (for webpages).

HTML TextOutput
<b>My symbol: &#8909;</b>My symbol: ⋍

(Method 4) Use the HTML Entity Code (for webpages).

HTML TextOutput
<b>My symbol: &bsime;</b>My symbol: ⋍

(Method 5) Use the CSS Code (for webpages).

CSS and HTML TextOutput
<style>
span:after {
content: "\22CD";}
</style>
<span>My symbol:</span> 		My symbol: ⋍

(Method 6) Use the HTML Hex Code (for webpages and HTML canvas).

HTML TextOutput
<b>My symbol: &#x22CD;</b>My symbol: ⋍
On the assumption that you already have your canvas and the context set up, use the Hex code in the format 0x22CD to place the ⋍ symbol on your canvas. For example:
JavaScript Text
const x = "0x"+"E9"
ctx.fillText(String.fromCodePoint(x), 5, 5);
Output

⋍

(Method 7) Use the Unicode (for various, e.g. Microsoft Office, JavaScript, Perl).

The Unicode for ⋍ is U+22CD. The important part is the hexadecimal number after the U+, which is used in various formats. For example, in Microsoft Office applications (e.g. Word, PowerPoint), do the following:
TypeOutput
22CD
[Hold down Alt]
[Press x]		⋍
(The 22CD turns into ⋍. Note that you can omit any leading zeros.)
In JavaScript, the syntax is \uXXXX. So, our example would be \u22CD. (Note that the format is 4 hexadecimal characters.)
JavaScript TextOutput
let str = "\u22CD"
document.write("My symbol: " + str)		My symbol: ⋍
