1. Let A = {2, 3, 4, 5, 6} and B = {10, 11, 12, 13}. Define a relation R on (A x B) as follows: a Rb if and only if gcd(a, b) = 1. a) Write out the elements of the relation R explicitly (remember, R is the set of ordered pairs from (A x B) that satisfy the given property). b) Write out the elements of the relation R1 explicitly.
A conjunt "C" groups 8 topics from the calculus course (a,b,c,d,e,f,g,h) trying to identify the liking for the course, a relation T in CxC is generated such that (x,y) ∈ T if and only if "the topic y is liked as much or more than the topic x". The answers are set out in the following Hasse diagram: (image) What is the favorite topic for the students? and What is the topic that students like the least?
For the set A = {are, bot, cab, era}, define the relation R on A to be: (x,y) e R if and only if word x and word y share one letter only. For example (are, cab) is in R because those words share one letter only ("a"). But (are, era) is NOT in R because those words do NOT share one letter only, they share 3 letters. Also (bot, era) is NOT in R since they share no letters at all. In cach part, answer yes or no. If yes, then explain why in terms of this specific relation about sharing letters (not just by stating the generic definition of the property). If you say a) Is R reflexive? b) Is R symmetric? c) Is R antisymmetric? d) Is R transitive?
