    Study Notes

    Module Overview

    • Focuses on understanding set theory and its applications.
    • Encourages collaborative learning through the formation of learning groups.

    Module Logistics

    • Prohibited: Plagiarism and unauthorized use of AI tools.
    • Encouraged: Active participation in discussions and collaborative projects.

    Learning Objectives

    • Aim to build critical thinking and problem-solving skills.
    • Develop clear understanding of set operations and relationships.

    Importance of Learning Groups

    • Facilitates deeper understanding through peer discussions.
    • Provides support and diverse perspectives for tackling complex topics.

    Consequences of Academic Misconduct

    • Incidences of plagiarism and AI use may result in disciplinary action.
    • Can lead to failure in the module and academic penalties.

    Set Theory Fundamentals

    • A set is defined as a collection of distinct objects or elements.
    • 'A is a subset of B' is represented by the notation ( A \subseteq B ).

    De Morgan's Law

    • States that the complement of a union is the intersection of the complements, and vice versa.

    Set Complement

    • The complement of set A includes all elements not in A.
    • Denoted by ( A' ) or ( \overline{A} ).

    Cartesian Product

    • The Cartesian product of sets A and B consists of all ordered pairs (a, b) where ( a \in A ) and ( b \in B ).

    Disjoint Sets

    • Disjoint sets are defined as sets that have no elements in common.

    Set Operations Notation

    • The union of two sets is represented by ( A \cup B ).
    • The symbol '∈' indicates that an element belongs to a set.
    • The symbol '∉' denotes that an element does not belong to a set.

    Universal and Natural Sets

    • The universal set includes all possible elements in a particular context.
    • The set of all natural numbers is often denoted as ( \mathbb{N} ).

    Set Differences

    • The difference of two sets A and B consists of elements in A that are not in B.
    • Equal sets have the same elements, meaning ( A = B ) entails ( A \subseteq B ) and ( B \subseteq A ).

    Other Set Notations

    • ( A \subset B ) indicates that A is a proper subset of B, meaning A is contained within B but not equal to it.
    • The intersection of two sets is represented by ( A \cap B ) and consists of elements common to both sets.
    • 'Empty sets' are called empty because they contain no elements.
