The Greek lowercase epsilon ε, the lunate epsilon symbol ϵ, or the Latin lowercase epsilon ɛ (see above) is used as the symbol for:
any number at all
By itself, nothing: it all depends on the context. epsilon is a letter of the Greek alphabet which is used in calculus to represent a very small number.
The greek letter closest to representing the latin letter e is epsilon (ɛ). In math's, epsilon is mainly used to represent very small positive numbers (e.g. when working with proofs), and used as the Levi-Civita symbol (a.k.a. the permutation symbol, used in tensor calculus, sometimes uses upper epsilon E, instead of lower epsilon ɛ). It is also often used in statistics and numerical analysis to represent errors.
'Epsilon' is the fifth letter in the Greek alphabet. When used as a symbol to represent math and science things, its value completely depends on the definition you give it. For example, if you were to define epsilon as the wavelength of blue light in feet, then its value would be 0.0000013123 (rounded), whereas if you define epsilon as the average distance between the Earth and sun in Astronomical Units, then its value is precisely 1.0000 . It all depends on your definition of epsilon.
It represents a number.
In mathematics (in particular calculus), an arbitrarily small positive quantity is commonly denoted ε; see (ε, δ)-definition of limitIn mathematics, Hilbert introduced epsilon terms as an extension to first order logic; see epsilon calculus.In mathematics, the Levi-Civita symbol.In mathematics, to represent the dual numbers: a + bε, with ε2 = 0 and ε ≠ 0.In mathematics, sometimes used to denote the Heaviside step function.
In math, a value that represents a constant relationship is given a Greek letter to represent it. Examples are epsilon and sigma functions.The ratio of the circumference to the diameter of a circle is about 3.14159 but can be calculated to an infinite number of places. This was assigned the Greek letter pi (π).
It can represent multiplication or a number that is the one which we are looking for.
