Uses of Greek letters

Greek letters used in mathematics, science, and engineering

The Greek letters are used in mathematics, science, engineering, and other aspects.

In mathematics, Greek letters are often used to represent constants, special functions, and some specific variables. In mathematics, uppercase and lowercase Greek letters usually have different meanings and are not related to each other.

Special functions refer to some functions with specific properties, generally with conventional names and symbols, such as gamma function, Bessel function, Fresnel integral, etc. They play an important role in mathematical analysis, functional analysis, physical research, and engineering applications. Many special functions are solutions of differential equations or integrals of basic functions, so special functions often appear in integral tables, and integrals often appear in the definitions of special functions.

Traditionally, the analysis of special functions is mainly based on their numerical expansion. With the development of electronic computing, new research methods have been pioneered in this field. Because of the importance of symmetries in differential equations in mathematics and physics, the theory of special functions is also closely related to Lie groups and Lie algebras.

There are some uppercase Greek letters whose writing is the same or very similar to the corresponding Latin letters and therefore will not be used, for example: A, B, E, H, I, K, M, N, O ,P,T,X,Y,Z. In addition, the lowercase letters ι (iota), ο (omicron) and υ (upsilon) are rarely used because they are similar to the Latin letters i, o and u. Sometimes font variants of Greek letters have specific meanings in mathematics, for example: φ (phi), π (pi).

In financial mathematics, the Greek letters (The Greeks) are variables used to represent investment risk.

When native English-speaking mathematicians pronounce Greek letters, they do not use the current or ancient pronunciation, but the traditional English pronunciation. For example: the letter θ, these mathematicians would pronounce it as [ ?θeit? ]. (Ancient: [ th^ε?ta ], present: [ ?θita ])?

Mathematical and printed script

The Greek alphabet used in mathematics and in Greek writing The Greek letters in are usually different: Greek letters used in mathematics are used independently, not connected to other letters. Also, some Greek letters used in mathematics use other styles than those used in printing.

There is a tag "mgrk" (Mathematical Greek, Greek letters used in mathematics) in the OpenType font format, which can be used to mark that a Greek letter is used in mathematics (not Greek).

The following table shows the difference between Greek letters in TEX (TeX) and HTML. The font used by TEX is italic because variables should be italicized. Since Greek letters are generally used for variables in mathematical formulas, Greek letters appear in fonts similar to TEX, usually in mathematical works.
