In each of 3-6, the relation R is an equivalence relation on A. As in Example 8.3.5, first find the specified equaivalence classes. Then state the number of distinct equivalenvce classes for R and list them.
Equivalence classes:[1], [2], [3], [4], [5].
To find the distinct equivalence classes of R.
Given information:
The relation R is an equivalence relation on the set A.
Calculation:
Let us first group the ordered pairs in R that have at least one common element (with at least one of the other elements in the group).
Thus
