Study Notes

Set Theory Basics

  • Members of a set are referred to as elements.
  • The symbol for conjunction is ∧.
  • A proposition's truth set includes all elements that make the proposition true.
  • The symbol for exclusive disjunction is ⊕ (or sometimes XOR).
  • The fundamental principle of set equality states that two sets are equal if they contain the same elements.

Statements and Truth Values

  • A statement is an unambiguous declarative sentence that can only be true or false.
  • An algorithm is a list of step-by-step instructions for carrying out a process.
  • A declarative sentence cannot be simultaneously true, false, or ambiguous; it can only be true or false.

Discrete Mathematics

  • Discrete Mathematics is utilized to analyze mathematical structures that are fundamentally discrete rather than continuous.

Set Definitions and Symbolism

  • A set is a well-defined collection of distinct objects, considered as an object in its own right.
  • The symbol used to represent the set of outcomes for flipping a coin is typically {Heads, Tails}.
  • An unambiguous description of a collection of objects is called a set.

Union and Infinite Sets

  • The union of sets A and B is defined as the set containing all elements in A, in B, or in both.
  • An example of an infinite set could be the set of all natural numbers {1, 2, 3, ...}.

Logical Statements

  • The equivalent symbolic statement for "Ali is at school or Ali is at home" is S ∨ H.
  • If the universe is the set of integers, the truth set for the proposition "x is greater than 2" includes all integers greater than 2.
  • The complement of set A consists of all elements in the universal set that are not in A.
