Which Greek letter is used in maths or physics to represent a change or difference in a quantity?
"represents a voiced dental fricative , like the ""th"" in ""that"" or ""this"". It is romanized as ""d"" or ""dh"". The uppercase letter Δ can be used to denote: The lowercase letter δ (or 𝛿) can be used to denote: These characters are used only as mathematical symbols. Stylized Greek text should be encoded using the normal Greek letters, with markup and formatting to indicate text style. Delta (letter) Delta (uppercase Δ, lowercase δ or 𝛿; ""délta"", ) is the fourth letter of the Greek alphabet. In the system of Greek numerals it has a value of 4. It was"
"Greek letters used in mathematics, science, and engineering 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. In these contexts, the capital letters and the small letters represent distinct and unrelated entities. 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. Small ι, ο and υ are also rarely used, since they closely resemble the Latin letters i, o"

"and u. Sometimes font variants of Greek letters are used as distinct symbols in mathematics, in particular for ε/ϵ and π/ϖ. The archaic letter digamma (Ϝ/ϝ/ϛ) is sometimes used. 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. In mathematical finance, the Greeks are the variables denoted by Greek letters used to describe the risk of certain investments. The Greek letter forms used in mathematics are often different from those used in Greek-language text: they are designed to"
"Omicron Omicron (uppercase Ο, lowercase ο, literally ""small o"": όμικρον < ὂ μικρόν - ""ò mikrón"", micron meaning 'small' in contrast to ""omega"") is the 15th letter of the Greek alphabet. In the system of Greek numerals it has a value of 70. This letter is derived from the Phoenician letter ayin . In classical Greek, omicron represented the sound in contrast to ""omega"" and ""ου"" . In modern Greek, omicron represents the . Letters that arose from omicron include Roman O and Cyrillic O. The upper-case letter of omicron (O) was originally used in mathematics as a symbol for"
"deviation from a straight line; the second by Carpus of Antioch, who regarded it as the interval or space between the intersecting lines; Euclid adopted the third concept, although his definitions of right, acute, and obtuse angles are certainly quantitative. In mathematical expressions, it is common to use Greek letters (α, β, γ, θ, φ, . . . ) to serve as variables standing for the size of some angle. (To avoid confusion with its other meaning, the symbol is typically not used for this purpose.) Lower case Roman letters (""a"", ""b"", ""c"", . . . ) are also used,"
"for numbers. Alphabetic letters may be symbols for sounds. Personal names are symbols representing individuals. A red rose may symbolize love and compassion. The variable 'x', in a mathematical equation, may symbolize the position of a particle in space. In cartography, an organized collection of symbols forms a legend for a map. The word ""symbol"" derives from the Greek σύμβολον ""symbolon"", meaning ""token, watchword"" from σύν ""syn"" ""together"" and βάλλω ""bállō"" "" ""I throw, put."" The sense evolution in Greek is from ""throwing things together"" to ""contrasting"" to ""comparing"" to ""token used in comparisons to determine if something is genuine."""
"used to mean ""many"", or of the Greek letter ω (omega), the last letter in the Greek alphabet. Leonhard Euler used an open variant of the symbol in order to denote ""absolutus infinitus"". Euler freely performed various operations on infinity, such as taking its logarithm. This symbol is not used anymore, and is not encoded as a separate character in Unicode. In mathematics, the infinity symbol is used more often to represent a potential infinity, rather than to represent an actually infinite quantity such as the ordinal numbers and cardinal numbers (which use other notations). For instance, in the mathematical"
"sometimes it is instead called the """"Eta"" theorem"", as the capital Greek letter ""Eta"" (""Η"") is undistinguishable from the capital version of Latin letter ""h"" (""H"")""."" Discussions have been raised on how the symbol should be understood, but it remains unclear due to the lack of written sources from the time of the theorem. Studies of the typography and the work of J.W. Gibbs, seem to favour the interpretation of ""H"" as ""Eta"". The ""H"" value is determined from the function ""f""(""E"", ""t"") ""dE"", which is the energy distribution function of molecules at time ""t"". The value ""f""(""E"", ""t"") ""dE"""
"as a symbol in textual criticism for the Alexandrian text-type (from Hesychius, its once-supposed editor). In chemistry, the letter H as symbol of enthalpy sometimes is said to be a Greek eta, but since enthalpy comes from ἐνθάλπος, which begins in a smooth breathing and epsilon, it is more likely a Latin H for 'heat'. In information theory the uppercase Greek letter H is used to represent the concept of entropy of a discrete random variable. The lowercase letter η is used as a symbol in: These characters are used only as mathematical symbols. Stylized Greek text should be encoded"
"have led to records of over 70,000 digits. The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter, sometimes spelled out as ""pi,"" and derived from the first letter of the Greek word ""perimetros,"" meaning circumference. In English, is pronounced as ""pie"" (, ). In mathematical use, the lowercase letter (or π in sans-serif font) is distinguished from its capitalized and enlarged counterpart , which denotes a product of a sequence, analogous to how denotes summation. The choice of the symbol is discussed in the section ""Adoption of the"

Greeks (finance) In mathematical finance, the Greeks are the quantities representing the sensitivity of the price of derivatives such as options to a change in underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent. The name is used because the most common of these sensitivities are denoted by Greek letters (as are some other finance measures). Collectively these have also been called the risk sensitivities, risk measures or hedge parameters. The Greeks are vital tools"
"formatting to indicate the style of text. Omega Omega (capital: Ω, lowercase: ω; Greek ὦ, later ὦ μέγα, Modern Greek ωμέγα) is the 24th and last letter of the Greek alphabet. In the Greek numeric system/Isopsephy (Gematria), it has a value of 800. The word literally means ""great O"" (""ō mega"", mega meaning ""great""), as opposed to omicron, which means ""little O"" (""o mikron"", micron meaning ""little""). In phonetic terms, the Ancient Greek Ω is a long open-mid ""o"" , comparable to the vowel of British English ""raw"". In Modern Greek, Ω represents the , the same sound as omicron."

"Lorentz factor The Lorentz factor or Lorentz term is the factor by which time, length, and relativistic mass change for an object while that object is moving. The expression appears in several equations in special relativity, and it arises in derivations of the Lorentz transformations. The name originates from its earlier appearance in Lorentzian electrodynamics – named after the Dutch physicist Hendrik Lorentz. Due to its ubiquity, it is generally denoted ""γ"" (the Greek lowercase letter gamma). Sometimes (especially in discussion of superluminal motion) the factor is written as ""Γ"" (Greek uppercase-gamma) rather than ""γ"". The Lorentz factor ""γ"" is"
"Epsilon Epsilon (uppercase ', lowercase ' or lunate ; ) is the fifth letter of the Greek alphabet, corresponding phonetically to a . In the system of Greek numerals it also has the value five. It was derived from the Phoenician letter He . Letters that arose from epsilon include the Roman E, Ë and Ɛ, and Cyrillic Е, È, Ё, Є and Э. The name of the letter was originally (), but the name was changed to (""e psilon"" ""simple e"") in the Middle Ages to distinguish the letter from the digraph , a former diphthong that had come"
"Hilbert, Hurwitz, and other writers"". In the earliest usages, the Greek letter was an abbreviation of the Greek word for periphery (περιφέρεια), and was combined in ratios with δ (for diameter) or ρ (for radius) to form circle constants. (Before then, mathematicians sometimes used letters such as ""c"" or ""p"" instead.) The first recorded use is Oughtred's ""formula_19"", to express the ratio of periphery and diameter in the 1647 and later editions of ""Clavis Mathematicae"". Barrow likewise used ""formula_20"" to represent the constant 3.14..., while Gregory instead used ""formula_21"" to represent 6.28... . The earliest known use of the Greek"
"Levi-Civita symbol In mathematics, particularly in linear algebra, tensor analysis, and differential geometry, the Levi-Civita symbol represents a collection of numbers; defined from the sign of a permutation of the natural numbers , for some positive integer . It is named after the Italian mathematician and physicist Tullio Levi-Civita. Other names include the permutation symbol, antisymmetric symbol, or alternating symbol, which refer to its antisymmetric property and definition in terms of permutations. The standard letters to denote the Levi-Civita symbol are the Greek lower case epsilon or , or less commonly the Latin lower case . Index notation allows one"

"('house'). In Greek, the name was ""bêta"", pronounced in Ancient Greek. It is spelled βήτα in modern monotonic orthography and pronounced . The letter beta was derived from the Phoenician letter beth . The letter Β had the largest number of highly divergent local forms. Besides the standard form (either rounded or pointed, ), there were forms as varied as (Gortyn), and (Thera), (Argos), (Melos), (Corinth), (Megara, Byzantium), (Cyclades). In the system of Greek numerals, beta has a value of 2. Such use is denoted by a number mark: Β′. Beta is used in finance as a measure of investment"
"Mu (letter) Mu (uppercase Μ, lowercase μ; Ancient Greek , or μυ—both ) or my is the 12th letter of the Greek alphabet. In the system of Greek numerals it has a value of 40. Mu was derived from the Egyptian hieroglyphic symbol for water, which had been simplified by the Phoenicians and named after their word for water, to become 𐤌 (mem). Letters that arose from mu include the Roman M and the Cyrillic М. In Ancient Greek, the name of the letter was written and pronounced [mŷː]. In Modern Greek, the letter is spelled and pronounced .

"Pi The number () is a mathematical constant. Originally defined as the ratio of a circle's circumference to its diameter, it now has various equivalent definitions and appears in many formulas in all areas of mathematics and physics. It is approximately equal to 3.14159. It has been represented by the Greek letter """" since the mid-18th century, though it is also sometimes spelled out as ""pi"". It is also called Archimedes' constant. Being an irrational number, cannot be expressed as a common fraction (equivalently, its decimal representation never ends and never settles into a permanently repeating pattern). Still, fractions such"

Greek letters are used to denote the brighter stars within each of the eighty-eight constellations. In most constellations, the brightest star is designated Alpha and the next brightest Beta etc. For example, the brightest star in the constellation of Centaurus is known as Alpha Centauri. For historical reasons, the Greek designations of some constellations begin with a lower"
"( or ). Archaic crossed forms of theta are seen in the wheel letters of Linear A and Linear B. The cursive form ϑ was retained by Unicode as U+03D1 ϑ ""GREEK THETA SYMBOL"" (""=script theta""), separate from U+03B8 θ ""GREEK SMALL LETTER THETA"". For the purpose of writing Greek text, the two can be font variants of a single character, but θ and ϑ are also used as distinct symbols in technical and mathematical contexts.
