Homework Statement
For each of the following relations on the set of all real numbers, say whether it is reflexive, symmetricm anti-symmetric, and transitive.
Homework Equations
c)x=1
The Attempt at a Solution
According to class notes I took, as this simple question was solved in class
Reflexive: no (2,2) is not in the relation
Symmetric: no if(1,2)[tex]\in[/tex]R(relation,not real number) but (2,1)[tex]\notin[/tex]R
Anti-symmetric: yes
let (x,y)[tex]\in[/tex]R
===>x=1
if y[tex]\neq[/tex]x, then y[tex]\neq[/tex]1 and (y,x)[tex]\notin[/tex]R since y[tex]\neq[/tex]x=1
Transitive?
Yes
let (x,y)[tex]\in[/tex]R and (y,z)[tex]\in[/tex]R
===> x=1 and y=1
===> (x,z)[tex]\in[/tex]R
My question is .. how is it possible that it is not reflexive transitive, symmetric or for that matter is anti-symmetric?
How is it possible that y does exists in the relation? Wouldn't that be a false value to begin with? As in if we have a false value then we cannot compare it to the existing relation?
