I am having difficulty understanding the Cartesian Rule for the type of sets R1 and R2 and the transactive of R3. This is a question on my practice paper.
Extracted text: (iii) R1 ° R2 (iv) Determine whether R3 is transitive.
Extracted text: Let A = {1, 2, 3, 4, 5}. Define the following relations on A. R1 = {(1,1), (1,2), (2,1), (3,2), (3,5), (4,4), (5,3)} R2 = {(1,2), (1,5), (2,3), (3,2), (5,3)} R3 = {(1,2), (1,5), (2,4), (3,1), (3,5), (4,4), (5,1), (5,3)}
