What Does The Weird R Symbol Mean In Math

What Does The Weird R Symbol Mean In Math - Intuitively, it means that for every $x \in R$, the function f will give back a value $f(x) \in R$. For example, a function $f(x)=1/x$ is only defined for those $x \in R$ Real Numbers $R$ that are different from $0$, so you should write $f: R/\ 0 \ \rightarrow R$.

As long as the category theory is concerned: The symbol ≅ is used for isomorphism of objects of a category, and in particular for isomorphism of categories (which are objects of CAT ). The symbol ≃ is used for equivalence of categories. ∈ (mathematics) means that it is an element in the set of… For eg...x ∈ ℕ denotes that x is within the set of natural numbers. The relation "is an element of", also called set membership, is denoted by the symbol "∈". Writing \displaystyle x\in A x\in A means that "x is an element of A".
