But that seems overly confusing, doesn’t it? Let’s make this easier to understand. A relation shows an association of objects from one set with objects … See more What this means is that we are familiar with relations. We will generalize these relationships by learning how to write and modeling them using matrices and directed graphs. See more Suppose set A = {1,2,3,4} and Set B = {0,2,4,6} and relation aRb such that a < b. Using the roster method, list the elements of R. See more Now that we’ve seen how to represent a relation using the roster method and how to combine relations using known set operations, it’s time to see how we can display relations graphically using Incidence Matrices … See more It’s important to note that a relation from set A to set B is a subset of A x B.
