Complexes

Complexes
represents the domain of complex numbers, as in .
  • evaluates immediately only if x is a numeric quantity.
  • Simplify 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.

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:
