• Algebraics 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.
