Complexes

Complexes

represents the domain of complex numbers, as in x∈Complexes.

Details

  • x∈Complexes evaluates immediately only if x is a numeric quantity.
  • Simplify[expr∈Complexes] can be used to try to determine whether an expression corresponds to a complex number.
  • The domain of real numbers is taken to be a subset of the domain of complex numbers.
  • Complexes is output in StandardForm or TraditionalForm as TemplateBox[{}, Complexes]. This typeset form can be input using comps.

Basic Examples  (3)

is a complex number:

Exponential of a complex number is a complex number:

Find complex numbers that make an inequality well defined and True:

Scope  (2)

Specify that all variables should be considered complex, even if they appear in inequalities:

By default, Reduce considers all variables that appear in inequalities to be real:

For every real number y there exists a complex number whose square is real and less than y:

By default, Resolve considers all variables that appear in inequalities to be real:
