16.2 Math symbols

LaTeX provides almost any mathematical or technical symbol that anyone uses. For example, if you include $\pi$ in your source, you will get the pi symbol π. See the “Comprehensive LaTeX Symbol List” package at https://ctan.org/pkg/comprehensive .

Here is a list of commonly-used symbols. It is by no means exhaustive. Each symbol is described with a short phrase, and its symbol class, which determines the spacing around it, is given in parenthesis. Unless said otherwise, the commands for these symbols can be used only in math mode. To redefine a command so that it can be used whatever the current mode, see \ensuremath .

Defining operators.

As we know, LaTeX has many commands to typeset operators , which are traditionally typeset using upright font—for example, sin, log etc. Obviously, the catalog of LaTeX’s operators is far from complete, especially because new ones are being constantly introduced. The question arises: what to do when we need a custom operator?

Probably one of the most often mistakes is to write something like

or, even worse,

sgn-bad

So what is the “right” way? As usually, there is more than one; but the simplest and cleanest one is to use the amsmath package:

(this is not necessary if you use one of the amsart, amsbook or amsrep classes) and then say

But there is one caveat. Some time ago I saw in my friend’s file the following code:

The result is disastrous: the space vanishes again! The explanation lies in the fact that TeX’s math mode treats everything in curly braces as an ordinary symbol, and we need an operator and not an ordinary symbol. The right way would be to define

—i.e., this would be the right way if there were no special command for that in the amsmath package. If you use some operator more often, it’s best to define it using the following construct:

where the first argument is the command and the second one the name to be typeset.

Again, there is a bit more to say. Assume that you want to have an operator like lim, which takes “limits” (in TeX’s terminology, this means that the sub- or superscript is to be placed below or above when in “displayed” mode). Then, you should use the starred version of \DeclareMathOperator:

ess sup

Introduction

Trigonometrical functions, logarithms, and others can be written in a document by means of some special commands, as demonstrated in the following example:

 Open this example in Overleaf

This example produces the following output:

Sincos.PNG

The commands will print the name of the function in upright (Roman) text instead of italics.

Operators in different contexts

Some operators can take parameters that are handled in a special way, for instance, limits.

OperatorsEx2.png

The package amsmath is needed for the macro \to ; without this package, \rightarrow has to be used.

Notice how the limit declaration can include a subscript. See the reference guide for a complete list of available operators.

Some languages may add or change some commands, check the main page for language-specific articles.

Defining your own operators

If you need to add a personalized operator to be displayed in Roman font instead of italics use \DeclareMathOperator

OperatorsEx3.png

The command \DeclareMathOperator takes two parameters, the first one is the name of the new operator and the second one is the text to be displayed. For this command to work you have to import the package amsmath in the preamble with

The command can be slightly modified if you need that your defined operator uses subscripts, as the \lim operator, in such case use \DeclareMathOperator* .

Assignments

Assignments, also known as homework, are usually given to school or university students to reinforce their knowledge of a subject and aid in learning. They are typically structured in question and answer form to be completed by the student consecutively.

fphw Assignment

This template is for formatting assignments or homework in a clear and simple way. The title section at the top of the first page clearly displays the assignment, student and class information. This information also appears in the headers and footers of subsequent pages. Questions in the assignment are clearly demarcated and appear inside boxes to focus attention. The template features examples of including images, tables, equations and code listings for covering virtually all common assignment information. Multi-part questions and answers are shown for more complex questions.

  • View Template Information

Wenneker Assignment

This template can be used by teachers or students for school or university assignments. It contains a clear title section at the start to specify the assignment class, title, date and teacher/student name. The template supports up to 4 levels of sections to structure the assignment into sections, questions, subquestions and bonus content. Examples of common assignment content are included: figure, equations, lists, table, code and paragraphs of text.

Lachaise Assignment

This template is for teachers/instructors/educators to create assignments/homework for their students. It includes a clear title on the first page for the course, assignment and teacher’s name, as well as the institution and date. Sets of questions can be grouped by headings and the template includes examples of unnumbered and numbered sections, and numbered subsections (for longer assignments). Amongst the description text for each question, examples are provided for virtually any subject matter, including: equations, algorithms, code and command line outputs.

Cleese Assignment

This template comes in two versions, one for teachers/instructors/educators to create assignments/homework for their students to fill out by hand, and another for students proficient in LaTeX to answer questions posed to them at school or university/college. Both versions contain simple environments for each question and subquestion within, and allow answer boxes to be created with either an answer or blank for space to write an answer. Sets of questions can be grouped by headings and the template includes examples of including an image, table, equation and code within questions.

    This operator changes when used alongside. text \( \lim_{h \to 0} (x-h) \) . \end{ document } Open this example in Overleaf. This example produces the following output: The package amsmath is needed for the macro \to; without this package, \rightarrow has to be used. Notice how the limit declaration can include a subscript.

  3. Math symbols (LaTeX2e unofficial reference manual (September 2023))

    The following symbols are most often used in plain text but LaTeX provides versions to use in mathematical text. \mathdollar ¶. Dollar sign in math mode: $. \mathparagraph ¶. Paragraph sign (pilcrow) in math mode, ¶. \mathsection ¶. Section sign in math mode: §. \mathsterling ¶. Sterling sign in math mode: £.

  12. operators

    In computer programming languages, the equals sign typically denotes either a boolean operator to test equality of values (e.g. as in Pascal or Eiffel), which is consistent with the symbol's usage in mathematics, or an assignment operator (e.g. as in C-like languages). Languages making the former choice often use a colon-equals (:=) or ≔ to ...

    13. Pseudocode has a different purpose compared to the actual programs. It should convey ideas, not implementation, and as such should be as close to the natural language as possible. Therefore I think it's not good to introduce programming language-specific syntax in the algorithm listing. I suggest one of these options:
