Given relations R1 = {(1, 2), (3, 4)} and R2 = {(2, 3), (4, 5)}, compose the two relations and find R1 o R2.
💡 Hint: Trace the paths to find the pairs that link through common elements.
Construct the reflexive closure for the relation R = {(1, 2), (2, 3)} on set A = {1, 2, 3}.
💡 Hint: Ensure every element in A links to itself.
