1, Greek letter

Greek alphabet is a letter used in Greek, and it is also widely used in mathematics, physics, biology, chemistry, astronomy and other disciplines. Greek letters are similar to English letters and Russian letters, but with different symbols and the same phonetic properties. Greek letters are the earliest letters with vowels in the world. Cyrillic letters and Georgian letters used in Russian and Ukrainian are all developed from Greek letters, so people who have studied Russian will feel deja vu when they use Greek letters. Greek letters have entered the vocabulary of many languages. For example, the international word Delta comes from the Greek letter δ, because δ is a triangle.

2. Greek letters in the field of science.

Greek letters used in mathematics, science and engineering.

The Greek alphabet is used in mathematics, science, engineering and other fields.

In mathematics, Greek letters are usually used to represent constants, special functions and some specific variables. In the field of mathematics, the meanings of uppercase and lowercase Greek letters are usually different and irrelevant.

Some capitalized Greek letters are the same or very similar to the corresponding Latin letters, so they are not used, such as: A, B, E, H, I, K, M, N, O, P, T, X, Y, Z. In addition, lowercase ι(iota), ο(omicron) and μ (up Sometimes, font variants of Greek letters have specific meanings in mathematics, such as φ(phi) and π(pi).

In financial mathematics, Greek letters are variables used to represent investment risks.

Mathematicians whose mother tongue is English don't read Greek letters with modern or ancient pronunciations, but read traditional English pronunciations. For example, the letter θ, these mathematicians will read it as [? θeit？ ]。 (In ancient times: [th^ε? Ta], nowadays: [? θita ])？

Mathematical style and printing style

The Greek letters used in mathematics are usually different from those in Greek characters: the Greek letters used in mathematics are used independently and are not connected with other letters. In addition, some Greek letters used in mathematics use other styles, rather than those used in printing.

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

The following table shows the differences between the Greek letters in TEX and HTML. TEX uses italics, because variables should be italics. Because Greek letters are generally used for variables in mathematical formulas, they appear in fonts similar to TEX, which are generally used in books about mathematics.
