Study Notes
Purpose of a Truth Table
- A truth table is used to calculate the validity of logical arguments and to test the consistency of a set of statements.
Logical Connectives
- There are five basic logical connectives: implication (→), negation (¬), conjunction (∧), disjunction (∨), and biconditional ().
Implication Connective
- The implication connective is represented by the symbol '→' in a truth table.
- The truth table for the implication connective shows that if P is true and Q is false, then P → Q is false.
Negation Connective
- The negation connective is represented by the symbol '¬' in a truth table.
- The truth table for the negation connective shows that ¬P is true when P is false, and ¬P is false when P is true.
Conjunction Connective
- The conjunction connective is represented by the symbol '∧' in a truth table.
- The truth table for the conjunction connective shows that P ∧ Q is true when both P and Q are true, and false otherwise.
- The truth value of 'P ∧ Q' is false when P is true and Q is false.
Disjunction Connective
- The disjunction connective is represented by the symbol '∨' in a truth table.
- The truth table for the disjunction connective shows that P ∨ Q is false when both P and Q are false, and true otherwise.
- The truth value of 'P ∨ Q' is false when P is false and Q is false.
Biconditional Connective
- The biconditional connective is represented by the symbol '' in a truth table.
- The truth table for the biconditional connective shows that P Q is true when P and Q have the same truth value, and false otherwise.
