Beta (UK: / ˈ b iː t ə /, US: / ˈ b eɪ t ə /; uppercase Β, lowercase β, or cursive ϐ; Ancient Greek: βῆτα, romanized: bē̂ta or Greek: βήτα, romanized: víta) is the second letter of the Greek alphabet. In the system of Greek numerals, it has a value of 2.

The beta function was studied by Leonhard Euler and Adrien-Marie Legendre and was given its name by Jacques Binet; its symbol Β is a Greek capital beta. Properties
In probability theory and statistics, the beta distribution is a family of continuous probability distributions defined on the interval [0, 1] or (0, 1) in terms of two positive parameters, denoted by alpha (α) and beta (β), that appear as exponents of the variable and its complement to 1, respectively, and control the shape of the distribution.
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. The symbol ϰ ("kappa symbol") is a cursive form of kappa (κ), used as a technical symbol.

The symbol in the International Phonetic Alphabet that represents this sound is β , and the equivalent X-SAMPA symbol is B. The official symbol β is the Greek letter beta. This letter is also often used to represent the bilabial approximant, though that is more precisely written with a lowering diacritic, that is β̞ .
The cursive form ϑ was retained by Unicode as U+03D1 ϑ GREEK THETA SYMBOL, separate from U+03B8 θ GREEK SMALL LETTER THETA. (There is also U+03F4 ϴ GREEK CAPITAL THETA SYMBOL .) 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 ...
