    00:58 Binary relation is a subset of the Cartesian product of two sets
    01:56 The relation R is defined as the set of ordered pairs where the elements are equal to each other.
    02:54 Relation R is created with ordered pairs where the first element is equal to the second element.
    03:52 Relation R represents a mapping from a set A to itself.
    04:50 The relation R consists of ordered pairs where the first element divides the second element.
    05:48 The number of relations on a set with n elements can be found by listing down all the subsets of A x A.
    06:46 The number of relations on a set A with n elements is equal to 2 to the power n square.
    07:39 The number of relations on a set A with n elements is 2 to the power n square.

    If I am not mistaken, in my university we defined a relation specifically as a non-empty subset of AxB. I wonder why this is? I cannot find this definition elsewhere.

    Let A={1,2,3,4} and let R be the releation on A defined by xRy if and onlyif " x divides y" written x/y.
    1) write down R as a set of ordered pairs.
    2) draw digraph of R.
    3) determine the indegree and outdegree vertices of digraph. Solve this problem please send me answer

    I think this divisibility needs to be clearly defined. When you say "a divides b", do you mean "b can be divided by a, evenly?"

    • @themid9itegamer9
      @themid9itegamer9 Před měsícem

      Technically a divides b means "b divided by a(without a remainder) " which is why we only have (3,3) and (3,6) for when a=3, because 3 can only divide 3 and 6 without remainder
