# Symmetric difference of relationships

## Homework Statement

2. Let R1 = {(1,1),(1,2),(2,3),(3.4), (2,4) } and
R2 = {(1,1),(2,2),(2,3),(3,3),(3,4) } be relations from {1,2,3} to {1,2,3,4}

R1⨁ R2

## The Attempt at a Solution

R1⨁ R2 = {(1,2), (2,2), (2, 4), (3,3)}

Is this correct?

If you defined

$$R_1\oplus R_2 = (R_1\cup R_2)\setminus (R_1 \cap R_2)$$
