represents the domain of algebraic numbers, as in x∈Algebraics.
- Algebraic numbers are defined to be numbers that solve polynomial equations with rational coefficients.
- x∈Algebraics evaluates immediately only for quantities x that are explicitly constructed from rational numbers, radicals, and Root objects, or are known to be transcendental.
- Simplify[expr∈Algebraics] can be used to try to determine whether an expression corresponds to an algebraic number.
- Algebraics is output in TraditionalForm as . This typeset form can be input using algs.
