Topics in Sets
1
Basic Concepts and Representations
- A set is a well-defined collection of distinct objects called elements
- Sets are denoted by capital letters (A, B, C) and elements by small letters (a, b, c)
- Two methods of representation: Roster method and Set-builder method
2
Subsets and Power Sets
- A ⊆ B means every element of A is also in B
- Proper subset: A ⊂ B when A ⊆ B and A ≠ B
- Empty set is subset of every set; every set is subset of itself
3
Set Operations - Union and Intersection
- Union (A ∪ B): elements in A or B or both
- Intersection (A ∩ B): elements common to both A and B
- Disjoint sets: A ∩ B = ∅
4
Complement and Difference Operations
- Complement A' = U - A (elements in U but not in A)
- A ∪ A' = U and A ∩ A' = ∅
- De Morgan's Laws: (A ∪ B)' = A' ∩ B' and (A ∩ B)' = A' ∪ B'
Key Concepts
A set is a wellEmpty Set (∅)If every element of AUnion (A ∪ B)Complement A'
