二元關係(binary relation) 探討兩物件之間關係形成的集合,記為「ρ」(發音為「rho」),兩物件 a 與 b 之間的二元關係記為「aρb」或「(a,b)∈ρ」,兩種表示方式實質等價。 一、單一集合的二元關係 二元關係為該集合本身笛卡爾積的子集。 舉例來說,若在集合 S 中包含 a、b、c 三個元素,則 S 的二元關...
Figure 1 compares relations that are functions and not functions.Figure 1. (a) This relationship is a function because each input is associated with a single output. Note that input qq and rr both give output nn. (b) This relationship is also a function. In this case, each input is ...

Relations between the generalized associated Legendre functions, Bessel functions, elliptic integrals and incomplete B-functionsThe Bessel function can be represented in terms of the confluent hypergeometric function by the formula [24]$$ J_{u}(z) = \\\frac{1}{\\\Gamma(1 +u)} \\\left( \...
Not all relations are function but all functions are relation. A good example of a relation that is not a function is a point in the Cartesian coordinate system, say (2, 3). Though 2 and 3 in (2, 3) are related to each other, neither is a function of the other. Function is a ...

In that scenario, there is more than one output for the input. Difference Between Relation and Function The difference between relation and function will be described later in the lesson. First, here is an overview of relations. There are different types of relations. In a one-to-one ...
Unfortunately, the term "function" is also used to refer to relations that map single points in the domain to possibly multiple points in the range. These "functions" are called multivalued functions (or multiple-valued functions), and arise prominently in the theory of complex functions, where...
