... “The equation y = sin(x)” is fine. An equation may involve any number of variables and does not distinguish between “domain” and “codomain”. IF an equation implies a unique y value for every x, or a unique x value for every y, these are called “implicit functions”. x3 = y5 generates an implicit func ...

... That is, the topology is closed under arbitrary unions and finite intersections. These sets in T are referred to as the open sets of our topological space. A set Y ⊂ X is called closed if its complement X \ Y is an element of T . Equivalently, one may define a topological space by specifying a colle ...

Math 541 Lecture #1 I.1: Topological Spaces
... If X has the trivial topology, then the closure of any point x ∈ X is all of X, and any real-valued continuous function defined on X is constant. If X has the discrete topology, then the closure of any point x ∈ X is itself, and any real-valued function defined on X is continuous. A function from on ...
