Give an example of a relation on a set that is a) both symmetric and antisymmetric. b) neither symmetric nor antisymmetric.

Sagot :

It should be noted that a relation that's both symmetric and antisymmetric is R = {a, b) | a= b}.

What is a relation?

A relation in mathematics simply means the relationship between two or more variables.

In this case, the relation that's both symmetric and antisymmetric is R = {a, b) | a= b}.

On the other hand, a relation on a set that is neither symmetric nor antisymmetric will be R = {a, b) | a < = b}

This is not symmetric because a < b and v < a can never be butt true.
