Equivalence class
Im trying to figure out equivalence relations. i get that for something to have an equivalence relation it must be reflexive, symmetric and transivitive. What im stuck with is working out the equivalence class.

The question i am faced with is "Describe the equivalence class for (1,0)."

Can anyone help?!

What is the equivalence relation? Then perhaps.

At the very least you know
$[(1,0)]\supset \{(1,0),(0,1),(1,1), (0,0) \}$
By reflexive, symmetry, and transitivity of the first two twice.
