    Answer:

    Definition : Given two non-empty sets A and B, the set of all ordered pairs (x, y),

    where x ∈ A and y ∈ B is called Cartesian product of A and B; symbolically, we write

    A × B = {(x, y) | x ∈ A and y ∈ B}

    If A = {1, 2, 3} and B = {4, 5}, then

    A × B = {(1, 4), (2, 4), (3, 4), (1, 5), (2, 5), (3, 5)}

    and B × A = {(4, 1), (4, 2), (4, 3), (5, 1), (5, 2), (5, 3)}

    (i) Two ordered pairs are equal, if and only if the corresponding first elements are

    equal and the second elements are also equal, i.e. (x, y) = (u, v) if and only if x =

    u, y = v.

    (ii) If n(A) = p and n (B) = q, then n (A × B) = p × q.

    (iii) A × A × A = {(a, b, c) : a, b, c ∈ A}. Here (a, b, c) is called an ordered triplet.

    2.1.2 Relations A Relation R from a non-empty set A to a non empty set B is a

    subset of the Cartesian product set A × B. The subset is derived by describing a

    relationship between the first element and the second element of the ordered pairs in

    A × B.

    The set of all first elements in a relation R, is called the domain of the relation R,

    and the set of all second elements called images, is called the range of R.

    For example, the set R = {(1, 2), (– 2, 3), (

    1

    2

    , 3)} is a relation; the domain of

    R = {1, – 2,

    1

    2

    } and the range of R = {2, 3}.
