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. In addition, there are two special accents that automatically adjust to theĬare should be taken when putting accents on lower-case i's and j's.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.
