Math::DomainError
Raised when a mathematical function is evaluated outside of its domain of definition.
For example, since cos returns values in the range -1..1, its inverse function acos is only defined on that interval:
Math.acos(42)
produces:
Math::DomainError: Numerical argument is out of domain - "acos"
