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( \...

Relation and Function 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 ...

Functions and Relations:We can relate any number of variables together to form a relation. If we only have two variables, this relation tells us the possible values of our second variable given specific values of our first variable. In order for a relation to be a f...
