It is used to denote thermal conductivity, susceptibility and curvature in differential geometry LambdaĪs the eleventh one in our list of Greek letters/symbols, lam(b)da ( λά(μ)βδα ) is written as Λ in uppercase and λ in lowercase. Kappa ( κάππα ) is the tenth letter in the Greek alphabet and is written as Κ in uppercase and κ in lowercase. The iota symbol is used to denote definite descriptor in logic and it is also used in several different ways in mathematics and programming languages. The ninth letter of the Greek alphabet, iota ( ιώτα ) is written as Ι in uppercase and ι in lowercase. It is used to represent time constant and angular phase displacement. The eighth letter of the Greek alphabet, Theta ( θήτα ) is written as Θ in uppercase and θ in lowercase. The uppercase letter is written as Η while the lowercase is η. EtaĮta ( ήτα ) is the seventh letter in the Greek alphabet used to denote coordinates, surface charge density and intrinsic impedance among other things. The zeta symbol is used to represent coefficients and coordinates in mathematics while it is also used in polymer and fluid dynamics as well. The sixth Greek letter zeta ( ζήτα ) is written as Ζ in uppercase and ζ in lowercase. Epsilon symbol denotes dual numbers and the Heaviside step function in mathematics along with some other things in other scientific areas. Delta symbol is used to denote deflection in engineering, density and angles along other things in science EpsilonĮpsilon ( έψιλον ) is the fifth letter of the Greek alphabet and it is written as Ε in uppercase and ε in lowercase. Deltaĭelta ( δέλτα ) is the fourth letter in the Greek alphabet It is written as Δ in uppercase and δ in lowercase. Gamma symbol is sued to denote propagation constants, specific gravity, electrical conductivity and complex propagation constants among other things. GammaĪs the third one in our list of Greek letters/Greek symbols, gamma ( γάμμα ) is written as Γ in uppercase and γ in lowercase. In addition to coefficients and angles, it is used to denote phase constants. Beta is written as B in uppercase and β in lowercase. If you would like to read more about the alpha symbol and its many meanings, check out our detailed article below: Betaīeta (βήτα) is the second letter in the Greek alphabet. It also has a powerful religious meaning within the context it was used in the Bible verses when God made the statement “I am the Alpha and Omega” as in “I am the beginning and the end of everything”. Alpha is written as A in uppercase and α in lowercase.Īlpha symbol is used to denote many things including absorption factor, area, angles and coefficients As Greek letters are more often than not used as variables in mathematical formulas, a Greek letter appearing similar to the TeX rendering is more likely to be encountered in works involving mathematics.Alpha ( άλφα ) is the first letter of the Greek alphabet. This is in line with the convention that variables should be italicized. The font used in the TeX rendering is an italic style. The table below shows a comparison of Greek letters rendered in TeX and HTML. The OpenType font format has the feature tag "mgrk" ("Mathematical Greek") to identify a glyph as representing a Greek letter to be used in mathematical (as opposed to Greek language) contexts. The Greek letter forms used in mathematics are often different from those used in Greek-language text: they are designed to be used in isolation, not connected to other letters, and some use variant forms which are not normally used in current Greek typography. In mathematical finance, the Greeks are the variables denoted by Greek letters used to describe the risk of certain investments. The Bayer designation naming scheme for stars typically uses the first Greek letter, α, for the brightest star in each constellation, and runs through the alphabet before switching to Latin letters. The archaic letter digamma (Ϝ/ϝ/ϛ) is sometimes used. Sometimes, font variants of Greek letters are used as distinct symbols in mathematics, in particular for ε/ϵ and π/ϖ. Small ι, ο and υ are also rarely used, since they closely resemble the Latin letters i, o and u. Those Greek letters which have the same form as Latin letters are rarely used: capital A, B, E, Z, H, I, K, M, N, O, P, T, Y, X. In these contexts, the capital letters and the small letters represent distinct and unrelated entities. Greek letters are used in mathematics, science, engineering, and other areas where mathematical notation is used as symbols for constants, special functions, and also conventionally for variables representing certain quantities.
