Equivalence Relations: Sample Problems

In this video, I work through an example of proving that a relation is an equivalence relation. We do this by showing that the relation is reflexive, symmetric, and transitive.

Finaly, what I expected...Very clear and to the point...Thank you!

wow thanks a lot, the best video that ive ever found about relations

In my opinion, if you are good at discrete math like this, you are a god damn genius

Sorry i cant understand the part where a-b = 3k, where a-b is divisible by 3. May I know how did you get 3k? as I thought it will be k/3 instead. Sorry!

Sir kia A intersection B equivalenc hy agar R or S equal houn

Hey may I ask a question: let’s say we have an equivalence relation aRb. Why can’t I represent this within set theory as set T comprising subset of Cartesian product of a and b, mapped to a set U which contains true or false? Thanks so much!!
