Reflexive Relations and Examples

Let A be a set. A relation R on A is a subset of A x A. Let R be a relation on A. We say R is reflexive of aRa for all a in A. In this video we go over this definition more carefully and we do several examples where we determine if the relation is reflexive. I hope this helps someone who is learning math and studying relations.

What does it mean for an element to relate to another between sets? Why is (2, 1) not valid but (1, 3) is?

Hey i was just revising relations and functions today so i wanna ask if in 2d corodinate plane a relation x, y which is also a function is 1d shape can in 3d coordinate geometry there be a funcrion which forms a 2d shape?
