Take the set A:={a,b,c,d,e,f}
(a)On A define the equivalence relation which belongs to the partition ({a,c,e,},{b,d,f}) and draw the graph of this relation.
(b)How many different equivalence relations exist on A?
(c)Prove that on the set NxN we get an equivalence relation by defining:
(x1,x2)rho(y1,y2):<=>x1+y2=x2+y1.
Please help me!!! |
