To insert the lambda, sigma and theta lettersin a Word document, you have different ways:
Copy and paste, or find out how to type infinity symbol ∞ directly from your keyboard whether you're on Windows, Mac, or Linux. You can put ∞ in Facebook, Instagram or Youtube. Mathematical infinity text sign. Alt codes and more. How to Use Symbols. First select the symbol then you can drag&drop or just copy&paste it anywhere you like. Alt-Codes can be typed on Microsoft Operating Systems: First make sure that numlock is on, Then press and hold the ALT key, While keeping ALT key pressed type the code for the symbol that you want and release the ALT key.
I. Using the Symbol font:
This method is very useful when you need to insert symbols rarely andit works only for Latin or Greek letters.
Anytime, when you type the text in the Word document, you can switch to the Symbolfont and use the corresponding Latin letters to enter Greek letters:
1. Click Ctrl+Shift+Q to switch your currentfont to the Symbol font.

2. Use symbols like normal font (e.g. in Symbolfont keyboard button 'a' equals Greek letter 'α', keyboard button 'b'equals Greece letter 'β', ..., 'l' ->'λ', ..., 'w' -> 'ω', etc.):
Note: This method works for inserting only one letter. Thus, if you want toinsert several symbols, you need to repeat these steps for each insertion.
After entering one letter using the Symbol font, the next character is entered usingthe previous font.
![Find Find](https://www.microsoft.com/en-us/microsoft-365/blog/wp-content/uploads/sites/2/migrated-images/48/8168.MathAutoCorrect.png)
If you click Ctrl+Shift+Q twice, Word does not switch to the previous font, and theSymbol font doesn't stop to work after the first entered symbol. Thus, you will needto change the current font and style later.
II. Using the Equation:
This way is perfect if you don't need to care about the format and compatibilitywith previous versions of Microsoft Office (a recommended approach for physicalscience and mathematics, which require a lot of math in the text with consistentfonts for all equations and symbols):
1. In the paragraph where you want to insert thesymbol, click Alt+= to insert the equitation block:
2. In the equitation block without any additionalefforts, you can enter any letter that you need just by typing+Name of the letter:
Note: You can create a shorter name, see the point III.2.
III. Using auto-replace:
When you work with many documents and often need to paste one specialsymbol, you may not want to insert an equation each time. Microsoft Word offers ahelpful feature named AutoCorrect. The AutoCorrect options in MicrosoftWord propose two different ways to quickly add any special character, such as alambda, sigma or theta letter from the Greek alphabet, or evenlarge pieces of text:
- Using the Math AutoCorrect options,
- Using the Replace text as you type function of the AutoCorrectoptions.
III.1. Using AutoCorrect for Math:
Using this method, you can benefit the Math AutoCorrect options without inserting anequation. To turn on or turn off the AutoCorrect of the Math symbols, do thefollowing:
1. On the File tab, click Options:
2. In the Word Options dialog box, on theProofing tab, click the AutoCorrect Options... button:
3. In the AutoCorrect dialog box, on theMath AutoCorrect tab, select the Use Math AutoCorrect rules outside of the math regionsoption:
After clicking OK, you can use any of the listed Names of symbols andMicrosoft Word will replace them to the appropriate symbols:
Note: If you don't need the last replacement, click Ctrl+Z to cancel it.

III.2. Using Replace text:
Using this method, you can come up with some sequence to use for replacing it to theLatin or Greek letter. For example, to replace some Greek letter with not short names,it is possible to use:
To define the new, short names to some Greek letters, do the following:
1. Insert the symbol for which you want to definethe short name, using the Symbol font and select it.
2. On the File tab, click Options.
3. In the Word Options dialog box, on theProofing tab, click the AutoCorrect Options... button.
4. In the AutoCorrect dialog box, on theAutoCorrect tab:
- Ensure that the Replace text as you type option is selected,
- The selected symbol has been inserted in the With field. If you use theFormatted text, select this radio button:
- In the Replace field, type the sequence that should be replaced to thesymbol,
- If such sequence doesn't used yet, click Add.
IV. Using a shortcut key:
Microsoft Word provides a way to define the shortcut key for the most often usedfunctions. Thus, you can assign a shortcut for inserting the lambda,sigma or theta letter:
1. On the Insert tab, in the Symbols group,click the Symbol button:
![Infinity Infinity](https://static.vecteezy.com/system/resources/previews/000/412/649/non_2x/love-word-in-the-sign-of-infinity-vector-calligraphy-and-lettering-eps10.jpg)
Note: If you use the character very often, you will find it in the Symboldropdown list:
2. Click More Symbols....
3. On the Symbol dialog box:
- To insert the lambda, sigma or thetafrom the current font (if exist), from theSubset dropdown list, select the Greek and Coptic:
- To insert the lambda, sigma or thetafrom the Symbol font, from theFont dropdown list, choose the Symbol font:
4. Choose the symbol and click the Shortcut Key...button to open the Customize Keyboard dialog box:
5. In the Press new shortcut key field, type the keycombination that you want to use for the symbol or character (e.g., for symbol λused Alt+L) and click Assign.
Note: Be careful, you can reassign the assigned already shortcuts in Word. Besure, that after Current assign to: there are no active Word functions. In any case,you can reassign any existing function in Word to a different key.

The infinity symbol (∞{displaystyle infty }, ∞, or in unicode ∞) is a mathematical symbol representing the concept of infinity. In algebraic geometry, the figure is called a lemniscate.
History[edit]
The shape of a sideways figure eight has a long pedigree; for instance, it appears in the cross of Saint Boniface, wrapped around the bars of a Latin cross.[1] However, John Wallis is credited with introducing the infinity symbol with its mathematical meaning in 1655, in his De sectionibus conicis.[1][2][3][4][5] Wallis did not explain his choice of this symbol, but it has been conjectured to be a variant form of a Roman numeral for 1,000 (originally CIƆ, also CƆ,[6] which was sometimes used to mean 'many'), or a variant of the Greek letter ω (omega)—the last letter in the Greek alphabet.[7]
Leonhard Euler used an open variant of the symbol[8] in order to denote 'absolutus infinitus'. Euler freely performed various operations on infinity, such as taking its logarithm. This symbol is not used anymore, and is not encoded as a separate character in Unicode.
Usage[edit]
In mathematics, the infinity symbol is used more often to represent a potential infinity,[1] rather than an actually infinite quantity as included in the extended real numbers, the ordinal numbers and the cardinal numbers (which use other notations).[9] For instance, in mathematical expressions with summations and limits such as the one below:
- ∑n=0∞12n=limx→∞2x−12x−1=2,{displaystyle sum _{n=0}^{infty }{frac {1}{2^{n}}}=lim _{xto infty }{frac {2^{x}-1}{2^{x-1}}}=2,}
the infinity sign is conventionally interpreted as meaning that the variable grows arbitrarily large towards infinity—rather than actually taking an infinite value.
The infinity symbol may also be used to represent a point at infinity, especially when there is only one such point under consideration. This usage includes, in particular, the infinite point of a projective line,[10][11] and the point added to a topological spaceT{displaystyle T} to form its one-point compactificationT∞{displaystyle T_{infty }}.[12]
In areas other than mathematics, the infinity symbol may take on other related meanings. For instance, it has been used in bookbinding to indicate that a book is printed on acid-free paper and will therefore be long-lasting.[13]
Modern symbolism[edit]
In modern mysticism, the infinity symbol has become identified with a variation of the ouroboros, an ancient image of a snake eating its own tail that has also come to symbolize the infinite, and the ouroboros is sometimes drawn in figure-eight form to reflect this identification—rather than in its more traditional circular form.[14]
In the works of Vladimir Nabokov, including The Gift and Pale Fire, the figure-eight shape is used symbolically to refer to the Möbius strip and the infinite, as is the case in these books' descriptions of the shapes of bicycle tire tracks and of the outlines of half-remembered people. The poem after which Pale Fire is entitled explicitly refers to 'the miracle of the lemniscate'.[15]
Graphic design[edit]
The well-known shape and meaning of the infinity symbol have made it a common typographic element of graphic design. For instance, the Métis flag, used by the Canadian Métis people since the early 19th century, is based around this symbol.[16] A rainbow-coloured infinity symbol is also used by the neurodiversity movement.[17] In modern commerce, corporate logos featuring this symbol have been used by, among others, the 2022 FIFA World Cup.[18]
Encoding[edit]
The symbol is encoded in Unicode at U+221E∞INFINITY (HTML ∞
·∞
) [19]and in LaTeX as infty
: ∞{displaystyle infty }.[20]
The Unicode set of symbols also includes several variant forms of the infinity symbol, that are less frequently available in fonts: U+29DC⧜INCOMPLETE INFINITY (HTML ⧜
·⧜
· ISOtech entity ⧜
), U+29DD⧝TIE OVER INFINITY (HTML ⧝
·⧝
) and U+29DE⧞INFINITY NEGATED WITH VERTICAL BAR (HTML ⧞
·⧞
) in block Miscellaneous Mathematical Symbols-B.[21]
