FilledSmallSquareBeta[a, b] gives the Euler beta function .

FilledSmallSquareBeta[z, a, b] gives the incomplete beta function .

FilledSmallSquare Mathematical function (see Section A.3.10).



FilledSmallSquareBeta[z, a, b] has a branch cut discontinuity in the complex z plane running from to .

FilledSmallSquareBeta[, , a, b] gives the generalized incomplete beta function .

FilledSmallSquare Note that the arguments in the incomplete form of Beta are arranged differently from those in the incomplete form of Gamma.

FilledSmallSquare In TraditionalForm, Beta is output using \[CapitalBeta].
