Question
(a) Give complete definitions of the terms
(i) Cartesian product of two sets;
(ii) relation on a set;
(iii) equivalence relation on a set.
(b) Write down examples of:
(i) a relation which is transitive but not reflexive;
(ii) an equivalence relation on {1, 2, 3, 4} with exactly three equivalence
classes.
(c) Let X and Z be any two sets, and f : X -
→ Z any function. Prove that
{(x, y) = X²: f(x) = f(y)}
is an equivalence relation on X.
