Misalkan R = {(1,2), (2,3), (3,4)} dan S = {(1,1), (1,2), (2,1), (2,2), (2,3), (3,1), (3,2), (3,4)} adalah relasi dari {1, 2, 3} ke {1, 2, 3, 4}. Tentukan :
a. R ∪ S
b. S ∩ R
c. R – S
d. S ⨁ R
Mohon Bantuanya
a.R U S = {(1,1), (1,2), (2,1), (2,2), (2,3), (3,1), (3,2), (3,4)}
b.S ∩ R = {(1,2), (2,3), (3,4)}
c.R – S = {}
d.S ⨁ R = {(1,1), (2,1), (2,2), (3,1), (3,2)}
