because LaTeX matters

The number of symbols that can be produced with TeX/LaTeX and the packages providing them is quite impressive. Often, I know the command by heart or a quick check on Google is sufficient to produce a specific symbol. However, it might happen that I don’t know the name of the symbol nor how to describe it. In that case, it’s good to know where to look.

Math symbols

Several websites have good collections of math symbols. These lists cover the most frequently used math symbols.

The amssymb package provides an extended symbol collection and is part of the AMSfonts packages . The symbols provided by the amssymb package are listed here .

Comprehensive List of Symbols

The comprehensive list of symbols lists close to 6000 symbols and their commands in LaTeX. The list contains mathematical symbols, phonetic symbols, currency symbols, legal symbols, science and technology symbols, arrows, and many others. It is an overwhelming collection, which might make it difficult to find the right symbol. The table of contents or the index at the end of the document are a good place to start looking.

The collection also contains unexpected symbols. For example, a recycling symbols ( \recycle ) provided by the recycle package .

$Recycle-symbol-latex$

Detexify

Another interesting and usefule resource is Detexify . Detexify is a service that recognises handwritten symbols and provides the command and the package to typeset them in LaTeX.

LaTeX Resources for Teachers

What is latex.

LaTeX is a free document preparation system which handles the typesetting of mathematical expressions smoothly and elegantly. Its history goes back several decades, and it has become the standard format for the creation and publication of research articles in mathematics and many scientific fields. In my opinion, LaTeX is also a good choice for math teachers.

The LaTeX system compiles commands and content specified in a plain text input file and produces a polished PDF output.

Getting started

Because LaTeX is designed primarily for research articles, custom commands are occasionally required to address teacher-specific formatting needs. For example, one might wish to include multiple questions per line or set up an arithmetic exercise in long division format. The templates below contain solutions I have used over the years.

LaTeX Questions Answered: What Kind of Symbols Can I Write Using LaTeX?

By jcaldwell January 5, 2022 Fiscal 2021-2022 , General , Homepage , LaTeX , Open Education

Lots! LaTeX allows you to write a wide variety of symbols, including Greek letters, arrows, operators, and relational symbols.

The following is an excerpt from the chapter LaTeX Questions Answered in Pressbooks Guide: A reference for open textbook authors using Pressbooks by Arianna Cheveldave

See the following table to learn the LaTeX commands for a selection of characters that can be found in the Pressbooks special character bank.

There are far too many LaTeX symbols to list here in full. However, we can link to a number of symbol resources, some of which give examples of how these symbols may be implemented in context.

Be aware that not every command listed in these resources will work in Pressbooks. See the Supported TeX/LaTeX commands page in MathJax’s documentation to view a full list of LaTeX commands that will work in Pressbooks.

The page of LaTeX symbols on the Art of Problem Solving wiki is an excellent introduction to some of the most common LaTeX symbols. This page also links to a number of other helpful resources for LaTeX symbols that are also included here.

Detexify is a web-based application with two features: “classify” and “symbols.” The “classify” feature allows you to draw your desired symbol, which generates a list of suggested commands. The “symbols” feature is an alphabetical, searchable list of symbol commands.

Math Vault’s Comprehensive List of Mathematical Symbols [PDF] is a compilation of many symbols in higher mathematics. This guide provides the LaTeX for each symbol and a rendered LaTeX expression containing the symbol. The primary purpose of the guide is to help math students expand their mathematical vocabulary: LaTeX is included to help those who would like to communicate with others on forums and write documents in LaTeX during their studies. So this guide may be useful as a reference, but bear in mind that its focus is not on teaching LaTeX.

The Comprehensive TeX Archive Network (CTAN) has an even more detailed resource called The Comprehensive LaTeX Symbol List [PDF] . This document is over 300 pages long and lists over 14,000 symbols, plus the LaTeX commands and packages required to create them. The table of contents divides the symbols into various broad groups, including body-text symbols, mathematical symbols, scientific symbols, and ancient language characters.

Problems in Mathematics

MathJax in WordPress and LaTeX for Math Blogs

$art of problem solving latex symbols$

The mathematical equations and symbols in this website is created using MathJax service. MathJax enables us to use LaTeX code in WordPress for mathematical equations/symbols.

My setting with macros

System of equations, augmented matrix, block matrix, matrix with fractions, elementary row operations (gauss-jordan elimination), use array for tabular, giving reasons for each line in align, second derivative, the length (magnitude) of vectors, explanations under equations, crossing things out, how to use mathjax on wordpress.

To use MathJax on WordPress, write the following code in header.php. (I put the code just before </head > .) That’s it!!

For example, if you type $\sin x$ in an editor, it gives $\sin x$.

creates \begin{align*} \cos^2 x +\sin^ 2 x=1 \end{align*}

Here is my current setting. The following codes include macros as well.

Useful LaTeX code for MathJax.

Here is the list of LaTeX codes that I used in this website and I found them useful.

Here is the LaTeX code for the system of equations.

If you don’t need the big bracket, then omit \left\{ and \right. from the above code. The LaTex code

To write a block matrix using MathJax, write the following LaTeX code

When you write a matrix whose entries are fractions, you might feel the line are cramped. So to widen the gap between lines, use \\[6pt] instead of \\ as in the following code.

To get \[ \left[\begin{array}{rrrr|r} 1 & 1 & 1 & 1 &1 \\ 0 & 1 & 2 & 3 & 5 \\ 0 & -2 & 0 & -2 & 2 \\ 0 & 1 & -2 & 3 & 1 \\ \end{array}\right] \xrightarrow{\substack{R_1-R_2 \\ R_3-R_2\\R_4-R_2}} \left[\begin{array}{rrrr|r} 1 & 0& -1 & -2 &-4 \\ 0 & 1 & 2 & 3 & 5 \\ 0 & 0 & 4 & 4 & 12 \\ 0 & 0 & -4 & 0 & -4 \\ \end{array}\right] \xrightarrow[\frac{-1}{4}R_4]{\frac{1}{4}R_3} \left[\begin{array}{rrrr|r} 1 & 0& -1 & -2 &-4 \\ 0 & 1 & 2 & 3 & 5 \\ 0 & 0 & 1 & 1 & 3 \\ 0 & 0 & 1 & 0& 1 \\ \end{array}\right] \] write the LaTeX code

The LaTeX code for the following table \begin{array}{ |c|c|c| } \hline a & a^2 \pmod{5} & 2a^2 \pmod{5} \\ \hline 0 & 0 & 0 \\ 1& 1 & 2 \\ 2& 4 & 3 \\ 3 & 4 & 3\\ 4 & 1 & 2\\ \hline \end{array} is

To give a reason how to obtain each equality, like \begin{align*} f(ab)&=(ab)^2 && (\text{by definition of $f$})\\ &=(ab)(ab)\\ &=a^2 b^2 && (\text{since $G$ is abelian})\\ &=f(a)f(b) && (\text{by definition of $f$}). \end{align*}

write the LaTex code

If the values of a function depends on cases (like parity), you might want to write: \begin{align*} \det(A)&=1+(-1)^{n+1} \\ &= \begin{cases} 2 & \text{ if } n \text{ is odd}\\ 0 & \text{ if } n \text{ is even}. \end{cases} \end{align*} The following LaTex code produces the above equation with cases:

When you want to say $A$ implies $B$, and want to write $A\implies B$, then use \implies for the allow $\implies$.

The opposite direction arrow $\impliedby$ is given by \impliedby .

When you want to say $A$ if and only if $B$, and want to write $A\iff B$, then use \iff for the allow $\iff$.

If you want to write the second derivative $f^{\prime\prime}$, then write the LaTeX code f^{\prime\prime} .

Note that for the first derivative $f’$, the latex code f' works but f'' produces $f”$.

To write a length of a vector such as \[\|\mathbf{v}\| \text{ or } \left\|\frac{a}{b}\right \|,\] use the LateX codes

If you want to add some explanations under an equation like \[n=\underbrace{1+1+\cdots+1}_{\text{$n$ times}},\] then use the Latex code

An integral of a function \[\int_{a}^{b} \! f(x)\,\mathrm{d}x\] is generated by the LaTex code

Note that \! narrows the space between the integral sign and the function, and \, increases the space between the function and $\mathrm{d}x$.

To strike through an expression obliquely like $\require{cancel}$$\cancel{A}$ to cancel the expression $A$, we first need to put the code

before the formula where you want to put $\cancel{A}$. You just need only one $\require{cancel}$ per page.

Then write the LaTex code \cancel{A} .

The following website contains more useful LaTex codes for MathJax.
