Definition of the set membership symbol. The symbol ∈ ∈ indicates set membership and means “is an element of” so that the statement x ∈ A x ∈ A means that x x is an element of the set A A. In other words, x x is one of the objects in the collection of (possibly many) objects in the set A A.Triangle. ABC has 3 equal sides. Triangle ABC has three equal sides. ∠. Angle. ∠ABC is 45°. The angle formed by ABC is 45 degrees. ⊥. Perpendicular.

Arithmetic mean. In mathematics and statistics, the arithmetic mean ( / ˌærɪθˈmɛtɪk ˈmiːn / arr-ith-MET-ik ), arithmetic average, or just the mean or average (when the context is clear) is the sum of a collection of numbers divided by the count of numbers in the collection. [1] The collection is often a set of results from an ...2 Answers. It means that f is a boolean function [the image is { 0, 1 } ], where the domain S has N elements. The function f can be thought of as a vector of length N as well, where writing S = { s 1, …, s n }, then f can be written f = ( f ( s 1), f ( s 2), …, f ( s n)). X Y denotes the set of functions from Y to X.In calculus and analysis, constants and variables are often reserved for key mathematical numbers and arbitrarily small quantities.

2 Answers. Sorted by: 11. The factorial of a number is represented by the exclamation point (!). The factorial of a number x x is often described as the product of all positive integers less then or equal to x x. For example: 4! = 4 ⋅ 3 ⋅ 2 ⋅ 1 = 24 4! = 4 ⋅ 3 ⋅ 2 ⋅ 1 = 24. It is often also useful to describe x! x! in a recursive ...The set made by combining the elements of two sets. So the union of sets A and B is the set of elements in A, or B, or both. The symbol is a special "U" like this: ∪. Example: Soccer = {alex, hunter, casey, drew} Tennis = {casey, drew, jade} Soccer ∪ Tennis = {alex, hunter, casey, drew, jade} In words: the union of the "Soccer" and "Tennis ...1. "a divides b" means a and b are integers and there is an integer n, such that n x a = b; or, if you prefer b/a ∈Z b / a ∈ Z, or if you prefer "a divides into b evenly with no remainder". The notation a|b a | b doesn't mean what you think it does. "|" isn't an operation that give a third value. a|b a | b is shorthand for the sentence "a ...

"Much less than" is a qualitative assessment of comparative inequality. a ≪ b means that a is not only less than b, but muchly so by some convention. That convention is fairly arbitrary, or rather contextual; there is no fixed quantitative basis. Sometimes it is based on additive position, sometimes on multiplicative magnitude.
