But I think it would more commonly be written R2 R 2, which is the set of pairs of real numbers. So my guess would be that saying (x, y) ∈ R2 ( x, y) ∈ ℜ 2 just means that x x and y y are both real numbers ...null set: In mathematical sets , the null set, also called the empty set, is the set that does not contain anything. It is symbolized or { }. There is only one null set. This is because there is logically only one way that a set can contain nothing.In mathematics, a rate is the quotient of two quantities in different units of measurement, often represented as a fraction.
