LaTeX has some handy macros that allow the insertion of diacritics and other special characters in text mode. These are handy since they don't require special input methods nor remembering unicode character numbers but, more importantly, mathematicians know and use them all the time. It would be nice if some useful subset of these were recognized on MathOverflow.

So you want to load even more javascript on us so that you don't have to remember how to input unicode characters? The above works on single commands. For example, the HTML entity for an accented letter replacing - with the letter is:.

Dorais They were the first examples that came to mind Some even actually use MathJax to get them to print, which is however unfortunate due to different font, rendering time, and some other reasons. Accents grave and circonflexe spring to mind. Dorais, I liked your list of the names better My point is, IMHO, we shouldn't be too picky about names.

German and French share most of their symbols with English but the symbols used by these names are not on standard English keyboards that we use. I generally appreciate when people try since my name has a diacritic and I like it, but that has no bearing on whether I would request this on their behalf or not. I am just saying that we should be tolerant to people whose native language is different from ours when they can't write our names properly.

Probably shouldn't have posted these under the question.

I found that my computer and browser, though perfectly capable of putting an acute accent on various letters, balked at putting it on a c they inserted a space and put the accent on that.

Kaveh: there is a difference between using a correct transliteration and dropping diacritics.

In my long document I, sadly, have to use several accents to denote different kinds of symbols.

Now I'd like to have no colors in my document, while I still have at least six different ways to differentiate certain symbols.

EDIT: The reader should be able to see the kind of accent used even if the symbol in question is in a sub-script possibly even a sub-sub-script. While you can do this, I'd revise my notation.

If you have the same base symbol with so many variants to distinguish, your gentle reader will soon be utterly confused.

I try to edit my answer for annuity hack. Sorry, I looked at solutions found on tex. It's a PhD thesis. Confusion, sadly, is expected. And there's not much "area" around that topic. I'll be open to comments from my fellow researchers, though.One of the greatest motivating forces for Donald Knuth when he began developing the original TeX system was to create something that allowed simple construction of mathematical formulae, while looking professional when printed.

The fact that he succeeded was most probably why TeX and later on, LaTeX became so popular within the scientific community. Typesetting mathematics is one of LaTeX's greatest strengths.

It is also a large topic due to the existence of so much mathematical notation. If your document requires only a few simple mathematical formulas, plain LaTeX has most of the tools that you will need. If you are writing a scientific document that contains numerous complicated formulas, the amsmath package [1] introduces several new commands that are more powerful and flexible than the ones provided by basic LaTeX.

The mathtools package fixes some amsmath quirks and adds some useful settings, symbols, and environments to amsmath. LaTeX needs to know when text is mathematical. This is because LaTeX typesets maths notation differently from normal text.

Therefore, special environments have been declared for this purpose. They can be distinguished into two categories depending on how they are presented:. As math requires special environments, there are naturally the appropriate environment names you can use in the standard way. Unlike most other environments, however, there are some handy shorthands to declaring your formulas. The following table summarizes them:. Furthermore, should a problem occur, the error messages may not be helpful.

If you are typing text normally, you are said to be in text modebut while you are typing within one of those mathematical environments, you are said to be in math modethat has some differences compared to the text mode :. Doing so might cause the line to be taller, but will cause exponents and indices to be displayed correctly for some math operators.

Mathematics has many symbols!

There is a set of symbols that can be accessed directly from the keyboard:. Beyond those listed above, distinct commands must be issued in order to display the desired symbols. There are many examples such as Greek letters, set and relations symbols, arrows, binary operators, etc.

Fortunately, there's a tool that can greatly simplify the search for the command for a specific symbol. Look for "Detexify" in the external links section below. Greek letters are commonly used in mathematics, and they are very easy to type in math mode.

You just have to type the name of the letter after a backslash: if the first letter is lowercase, you will get a lowercase Greek letter, if the first letter is uppercase and only the first letterthen you will get an uppercase letter. Lowercase epsilon, theta, kappa, phi, pi, rho, and sigma are provided in two different versions. The alternate, or var iant, version is created by adding "var" before the name of the letter:.

Scroll down to List of mathematical symbols for a complete list of Greek symbols. An operator is a function that is written as a word: e. LaTeX has many of these defined as commands:.This section will cover how to typeset mathematics. It will also cover how to handle complicated equations and multiple equation environments.

For many people the most useful part of LaTeX is the ability to typeset complex mathematical formulas.

This is achieved by the use of two operating modes, paragraph and math mode. There is also a third mode called LR mode, however, this is rarely used by beginners and furthermore, is usually implicitly entered with other commands.

It will not be covered here. Paragraph mode is the default mode for the document environment and does not need to be called explicitly. I almost always use the first two methods for typesetting basic math.

It appears you don't have a PDF plugin for this browser. You can click here to download the PDF file. Note that math mode ignores whitespace, in fact, this whole code could have been put on one line and still would have compiled correctly. This command forces LaTeX to give an equation the full height it needs to display as if it were on its own line.

Be careful in using it as it can make a document due to variable line height. There are several ways to format multiple equations and the amsmath package adds several more. Try the example on the right which sets the same multiple equations in several ways. Observe that the equation environment does not even allow line breaks. The gather and align environments both give us the result we want, albeit in slightly different manners.

Overview This section will cover how to typeset mathematics. What is math mode? The following table lists three methods and their usage of declaring math mode. Now try the following LaTeX code.

If we use the gather environment, every equation is centered. The following is a table of some of the most common LaTeX mathematical symbols. Table of Contents. Created by Zachary Glassman. Contact at zach.The feature that makes L a T e X the right editing tool for scientific documents is the ability to render complex mathematical expressions.

This article explains the basic commands to display equations. Basic equations in L a T e X can be easily "programmed", for example:.

Open an example in Overleaf. L a T e X allows two writing modes for mathematical expressions: the inline mode and the display mode. The first one is used to write formulas that are part of a text. The second one is used to write expressions that are not part of a text or paragraph, and are therefore put on separate lines.

They all work and the choice is a matter of taste. Below is a table with some common maths symbols. For a more complete list see the List of Greek letters and math symbols :. Different classes of mathematical symbols are characterized by different formatting for example, variables are italicized, but operators are not and different spacing.

The mathematics mode in LaTeX is very flexible and powerful, there is much more that can be done with it:. No Search Results. Mathematical expressions.In this chapter we will tackle matters related to input encoding, typesetting diacritics and special characters. In the following document, we will refer to special characters for all symbols other than the lowercase letters a—z, uppercase letters A-Z, figures 0—9, and English punctuation marks.

Some languages usually need a dedicated input system to ease document writing. This is the case for Arabic, Chinese, Japanese, Korean and others. This specific matter will be tackled in Internationalization. The rules for producing characters with diacritical marks, such as accents, differ somewhat depending whether you are in text mode, math mode, or the tabbing environment.

But characters is not enough to support non-English languages. TeX has its own way to do that with commands for every diacritical marking see Escaped codes. But if we want accents and other special characters to appear directly in the source file, we have to tell TeX that we want to use a different encoding.

It only defines those symbols that are known to be available with the current font encoding. You might encounter a situation where using UTF-8 might result in error:. This is due to the utf8 definition not necessarily having a mapping of all the character glyphs you are able to enter on your keyboard. Such characters are for example. In such case, you may try to use the utf8x option to define more character combinations.

However it might break up compatibility with some packages like csquotes. Another possiblity is to stick with utf8 and to define the characters yourself. This is easy:. TeX sequence is what to print when the character matching the codepoint is met. You may find codepoints on this site. Codepoints are easy to find on the web. This is convenient if your keyboard lacks some desired accents and other diacritics. The following accents may be placed on letters. Although 'o' letter is used in most of the examples, the accents may be placed on any letter.

Older versions of LaTeX would not remove the dot on top of the i and j letters when adding a diacritic. For example:.

However, current versions of LaTeX do not need this anymore and may, in fact, crash with an error. If a document is to be written completely in a language that requires particular diacritics several times, then using the right configuration allows those characters to be written directly in the document.

This is very useful if one needs to use some text accents in a label, since no backslash will be accepted otherwise. More information regarding language configuration can be found in the Internationalization section. This is a font encoding issue. If you want them to print their real symbol, you will have to use another font encoding such as T1, loaded with the fontenc package. See Fonts for more details on font encoding. When writing about money these days, you need the euro sign.

Depending on your chosen font this may be quite far from the official symbol. An official version of the euro symbol is provided by eurosym. Load it in the preamble optionally with the official option :. Finally, if you want a euro symbol that matches with the current font style e. Alternatively you can use the marvosym package which also provides the official euro symbol. There is a simple method to do that.Or, search for the description of the feature you want to use from the Help menu in Preview.
