WebIn geometry, a locus (plural: loci) (Latin word for "place", "location") is a set of all points (commonly, a line, a line segment, a curve or a surface), whose location satisfies or is determined by one or more specified conditions.. The set of the points that satisfy some property is often called the locus of a point satisfying this property. The use of the … WebIn set theory, the union (denoted by ∪) of a collection of sets is the set of all elements in the collection. [1] It is one of the fundamental operations through which sets can be combined and related to each other. A nullary union refers to a union of zero ( ) sets and it is by definition equal to the empty set. kristaps porzingis how tall

The Cartesian product P × Q is the set of all ordered pairs of elements from P and Q, i.e., P × Q = { (p,q) : p ∈ P, q ∈ Q} If either P or Q is the null set, then P × Q will also be an empty set, i.e., P × Q = φ.

WebIn set theory, the complement of a set A, often denoted by A ∁ (or A′), is the set of elements not in A.. When all sets in the universe, i.e. all sets under consideration, are considered to be members of a given set U, the absolute complement of A is the set of elements in U that are not in A..
