The Greek lowercase epsilon ε, the lunate epsilon symbol ϵ, and the Latin lowercase epsilon ɛ (see above) are used in a variety of places: In engineering mechanics, strain calculations ϵ = increase of length / original length. Usually this relates to extensometer testing of metallic materials. In mathematics

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.
The symbol ϵ (U+03F5) is designated specifically for the lunate form, used as a technical symbol. The symbol ϑ ("script theta") is a cursive form of theta (θ), frequent in handwriting, and used with a specialized meaning as a technical symbol.

As formulas are entirely constituted with symbols of various types, many symbols are needed for ...
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 ε or ϵ , or less commonly the Latin lower case e .
The normal letter epsilon (Ε) was used exclusively for the latter, while a new special symbol (or, in Sicyon, ) stood both for short /e/ and for /ɛː/. Yet another variation of the system is found in neighbouring Tiryns : it uses the letter forms of the Corinthian system, versus E, but with the functional values of the classic eta versus ...
