Short Answer TypeShow that the relation R in the set A of all the books in a library of a college given by R = {(x, y): x and y have same number of pages} is an equivalence relation.
Determine whether each of the following relations are reflexive, symmetric and transitive :
(i) Relation R in the set A = {1, 2, 3,....., 13, 14} defined as R = {(x, y) : 3 x – y = 0}
Determine whether each of the following relations are reflexive, symmetric and transitive :
(ii) Relation R in the set N of natural numbers defined as R = {(x, y) : y = x + 5 and x < 4}
Relation R is in the set N given by
R = {(x, y) : y = x + 5 and x < 4 }
∴ R = {(1,6), (2, 7). (3, 8)}
(a) R is not reflexive as (x, x) ∉ R (b) R is not symmetric as (x, y) ∈ R ⇏ (v, x) ∈ R (c ) R is not transitive as (x,y) ∈ R, (y, z) ∈ R ⇏ (x, z) ∈ R
Determine whether each of the following relations are reflexive, symmetric and transitive :
(ii) Relation R in the set A = {1, 2, 3, 4, 5, 6} as R = {(x,y) : y is divisible by x}
