Check points 2.1 set l is the set of the first six lowercase letters in the english alphabet. m {april, august} o {1, 3, 5, 7, 9} a. not the empty set; many numbers meet the criteria to belong to this set. b. the empty set; no numbers meet the criteria, thus this set is empty c. not the empty set; “nothing” is not a set. is iv.
Chapter 2 Set Theory Pdf Set Mathematics Numbers You know immediately that a set such as 1,3 is not a subset of b because it can’t be made by selecting elements from b, as the 3 is not an element of b and thus is not a valid selection. Representing sets a set is well defined if we are able to tell whether any particular object is an element of the set. example: which sets are well defined? a = { x : x is a winner of an academy award } t = { x : x is tall }. Solution: yes, f is onto since all three elements of the codomain are images of elements in the domain. if the codomain were changed to {1, 2, 3, 4}, f would not be onto. There is no repetition in a set, meaning each element must be unique. you could, for example, have variations on an element, such as a regular number 4 and a boldface number 4.

Definition 2.6. let e and f be sets. the (cartesian) product of e and f, denoted e f, is the set of all ordered pairs (x; y), where x is an element of e and y is an element of f. To describe subsets of u we give some property the elements have to satisfy, for example if u = r we could use the property x > 0 to form the subset of positive real numbers {x | x > 0}. Jaj is the cardinality, or size of a, namely the number of its elements (if a is nite; if a is in nite, one often writes jaj = 1 as a shorthand, although this isn't very precise).
