On a Mac, to enter the Infinity ∞ symbol: Command + Control + Spacebar shortcut to open the Character Viewer. Search for “ Infinity “ and the Viewer should find the symbol you need. Despite the name Character Viewer, the Apple system tool will also insert characters into any program, including Office for.

The infinity symbol (${\displaystyle \mathrm{\infty }}$, ∞, 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:

${\displaystyle \sum _{n=0}^{\mathrm{\infty }}\frac{1}{2^n}=\underset{x\to \mathrm{\infty }}{lim}\frac{2^x-1}{2^{x-1}}=2,}$

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 space${\displaystyle T}$ to form its one-point compactification${\displaystyle T_{\mathrm{\infty }}}$.^[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: ${\displaystyle \mathrm{\infty }}$.^[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] Don't starve together: wurt deluxe chest download free.

This book is about the Math Builder (officially called as Equation Editor) tool in Microsoft Word and Outlook 2007 and higher. It also applies to Microsoft PowerPoint and Excel 2010 and higher. Note that this is a different tool than the legacy tool Equation Editor 3.0 (which is still available on 32-bit Office versions until the January 2018 update^[1]) and MathType.

Typesetting mathematics on a computer has always been a challenge. The mathematical community almost universally accepts a typesetting language called LaTeX. Math Builder is a much easier to use tool that has less functionality than LaTeX but more than typical document processing. Microsoft call this hybrid language the Office Math Markup Language, or OMML for short. It is an appropriate tool for:

• Typing any document whose focus is not itself mathematics.
• Typing a short math document quickly.
• A stepping stone between word processing (MS Word) and typesetting (LaTeX)

Note that Math Builder does not perform any mathematics; it is a tool for displaying it.

Pros and Cons[edit]

Pros:

• Math Builder is WYSIWYG: after typing an equation you see immediately what it looks like.
• It's easy to get started: it's already built in to Microsoft Word. Common symbols have point-and-click icons.
• It's easy to use: Common symbols have keyboard shortcuts so that a veteran user need not use a mouse at all.
• Nearly all symbols use the same commands as LaTeX.
• The format used is non-proprietary and given in Unicode Technical Note #28.
• It can be used in Outlook to easily write equations in emails; it renders as images to the recipent.

Cons:

• Some uncommon symbols are not listed in the menu and require knowing the keyboard shortcut. Typically this is the LaTeX code for the symbol.
• There are differences between Math Builder and LaTeX code: advanced functionality that requires more than just a symbol tend to follow the same flavor but have slightly different syntax. Math Builder code tends to be shorter than LaTeX code and disappears upon completion to the WYSIWYG output. Examples here are matrices, multiple aligned equations, and binomial coefficients.
• No LaTeX typesetting tools such as labels and references are implemented.
• No highly advanced LaTeX tools such as graphing, commutative diagrams, or geometric shapes are implemented. (Note:- Geometric shapes are otherwise available in the Insert ribbon)
• Students studying mathematics might not be motivated to learn LaTeX because they might be able to get by with Equation Builder in Word to satisfy the vast majority of their needs. However, when such a student reaches the limits, unlike LaTeX there is absolutely no recourse to expand the program to satisfy it.

Inserting an equation[edit]

Microsoft Word has two different typing environments: text and math. To obtain the math environment, click on 'Equation' on the 'Insert' ribbon on Windows or Word for Mac '16, or in 'Document Elements' on Word for Mac '11. The keyboard shortcut is 'alt'+ '='. For a Mac system, the shortcut is control + '='. Everything you type in this environment is considered math: all automatic formatting of text is disabled. To exit the math environment, click on any text outside the math environment. One easy way to do this is by pressing the right arrow key.

Common Mathematics[edit]

Fractions[edit]

There are multiple ways to display a fraction. The default is vertically aligned as illustrated below. Obtain this by typing the fraction and pressing space: 1/2

${\displaystyle \frac{1}{2}}$

Linear fraction (resp. skewed fraction) is obtained using ldiv (resp. sdiv) and pressing space (twice) or by typing 1 ldiv 2 (resp. 1 sdiv 2) and pressing space. While you can also do this by right-clicking on the equation and clicking Linear, this affects the whole equation and not just the fraction.

${\displaystyle v/p}$

Parenthesis, brackets, and braces[edit]

Grouping symbols will automatically size to the appropriate size. These symbols include '(), {}, [], '. For instance, the expression below can be obtained with (1/2(x+1)):

${\displaystyle \left(\frac{1}{2}(x+1)\right)}$

Be careful to press space after the '2' to render the fraction, otherwise Word might put 'x+1' in the denominator. Also press space after typing every closing parenthesis ')', which will adjust both the opening and closing parentheses size to fit the group's contents. Because the 1/2 fraction is is quite tall, the outer parentheses need to be adjusted to enclose the fraction appropriately. To be exact, the key presses required to reproduce the equation above are (1/2space(x+1)space)space.

Exponents and subscripts[edit]

Exponents can be obtained by using '^' and subscripts by '_'. The monomial below can be obtained by typing x_2^5 or x^5_2 and pressing space.

${\displaystyle x_2^5}$

Symbols: ${\displaystyle \ne ,\le ,\subseteq ,\vee ,\to ,\Rightarrow }$ etc[edit]

These are all common symbols. The easiest thing to do would be to find a LaTeX reference sheet. A few of those symbols are shown here:

Greek, Script, and Fraktur letters[edit]

The math environment implements 3 fronts in addition to the default.

• Greek letters can be obtained by typing a ' followed by the name of symbol. Capitalizing it creates a capital letter. delta Delta produces ${\displaystyle \delta \mathrm{\Delta }}$
• Script letters can be obtained by typing ' followed by 'script' followed by the letter. scriptd scriptD produces ${\displaystyle \mathcal{d}\mathcal{D}}$
• Fraktur letters can be obtained by typing ' followed by 'fraktur' followed by the letter. Fraktur does not have capitals. frakturd prodouces ${\displaystyle \mathfrak{d}}$

Blackboard Bold letters[edit]

Blackboard bold letters can be obtained by typing ' followed by 'double' followed by the letter. doubled doubleD produces ${\displaystyle \mathbb{d}\mathbb{D}}$

Mathematical Physics[edit]

Vectors[edit]

A vector is often denoted by an overhead right arrow, which can be obtained by following a letter variable with 'vec': ${\displaystyle \overrightarrow{A}}$. Unit vectors (e.g. ${\displaystyle \hat{x}}$) are denoted by a hat (circumflex), which can be obtained by following a letter variable with 'hat'. The gradient (also known as del or nabla) operator ${\displaystyle \mathrm{\nabla }}$ may be displayed using 'nabla'.

Newtonian Dot Notation[edit]

Dot notation for time derivatives (e.g. ${\displaystyle \dot{r},\ddot{r}}$)can be obtained by following a letter variable with 'dot' for a first derivative and 'ddot' for a second derivative.

Vector Products[edit]

The dot product (inner product) can be displayed using the centered dot symbol 'cdot' e.g. the divergence ${\displaystyle \mathrm{\nabla }\cdot A}$. The cross product can be displayed using 'times' e.g. the curl ${\displaystyle \mathrm{\nabla }\times A}$.

Matrices[edit]

Matrices are obtained with the 'matrix' symbol. Use parentheses to start and end the matrix. Use '@' to separate rows, and '&' to separate columns. The matrix below can be created by typing [matrix(1&2&3@4&5&6)].

Multiple Aligned Equations[edit]

Aligning equations can be obtained with the 'eqarray' symbol. Use parentheses to start and end the matrix. Use '@' to separate equations. Use '&' to specify alignment and whitespace. The first '&' and then every other occurrence is alignment. The second and then every other occurrence is white space. The equations below can be obtained by typing the following text:

(The math environment here seems to be adding excess space between the alignments that doesn't occur in Word)

Radicals[edit]

Radicals are obtained using the 'sqrt' symbol, followed by the index, then '&', then the radicand.

For example: sqrt(a&b) will output ${\displaystyle \sqrt[a]{b}}$.

Additionally, sqrt(x) will simply output ${\displaystyle \sqrt{x}}$.

Integrals[edit]

Integrals are obtained by inserting the desired integral symbol (see above table), and then pressing space twice.^[2]

For example: int_a^bspacespace1/xspacedx will output ${\displaystyle \underset{a}{\overset{b}{\int }}\frac{1}{x}dx}$

Inline versus Display[edit]

Equations have two forms. Inline specifies that the equation is to be in line with text. This affects a few expressions to make them appear smaller. For instance fractions will use a smaller font. Summations and integrals will place the endpoints to the right of the symbol instead of below it.Display specifies to use as much space as needed. Display mode equations must appear on their own line.

Modifying and creating shortcuts[edit]

Everything in Math Builder requires special symbols that the computer knows how to interpret. These symbols are constructed with all the commands starting with ' as illustrated in the above sections. This is implemented via math autocorrect which you can modify. For instance, you might like to use ra instead of rightarrow. You can do this by adding the command to the math autocorrect directory.
