Page1/1            An equivalence relation 2009-04-22 From syed:D is the relation defined on Z as follows: Z is an integer For all m,n E Z, m D n if and only if 3 l (m^2 - n^2). Find out whether the above relation satisfies to reflexive , Symmetric & transitive? Is it an equivalence?Answered by Robert Dawson.     An equivalence relation 2008-08-27 From Francesca:In this problem we are told to find out if the given set is an equivalence relation or not. {(x,y) such that 4 divides x-y}. What I am confused about is whether or not for instance if I picked (1,5) as a part of the set whether I could put in (5,1) as well or whether that would be wrong. Thanks!Answered by Victoria West.     Equivalence relation 2008-03-19 From Hmod:State with reasons, whether the relation R on N X N given by mRn if m and n have difefrent remainders on division by 2 is an Equivalence relationAnswered by Victoria West.     Equivalence relations 2007-07-18 From jim:Determine whether the given relation is an equivalence relation on the set. Describe the partition arising from each equivalence relations. 1. x is Related to y in Real number if lxl=lyl. 2. n is Related to m in Z+ if n and m have the same number of digits in the usual base ten notation. Let n be a particular integer in Z+. Show that congruence modulo n is an equivalence relation on Z.Answered by Harley Weston.     Equivalence relations on a set of cardinality n 2002-07-06 From Siddhartha:what is the no. of equivalence and transitive relations on a set of cardinality n?Answered by Penny Nom.     Equivalence Relations 1999-05-06 From Megan:I am tutoring a boy who got this assignment from his teacher and I have no clue how to do it because I don't even know what the questions is asking! I need some help. Hereit is: "Give five examples of relations which are not equivalent relations and five examples of equivalent relations and explain why they are equivalent relations." This is seventh grade and I read about it in his book but it is not coming together for me.Answered by Chris Fisher.
