No CommentsAn Introduction to Truth Value Analysis
Description
A detailed tutorial on the introduction to truth value analysis. Step by step tutorial including several examples of the introduction to truth value analysis for reference.
Overview
Truth value analysis is where you get to use negation, conjunction, disjunction, and implication. You first want to start out by making a truth table. A truth table typically uses the letters P and Q, P as the antecedent or first statement and Q as the consequent or second statement. Then you can write in a statement such as “P implies Q” using either conjunction, disjunction, or implication, and declare it as true or false. Remember how to determine if a statement is true or false:
Conjunction: False ^ False = False, everything else is true
Disjunction: True V True = True, everything else is false
Conditional Implication: True => False = False, everything else is true
Biconditional Implication: True <=> True = True, False <=> False = True, everything is is false
Remember that the statements may look long and complicated sometimes, but each part in it can be broken down into something that is true and something that is false to find out if the entire statement is really true or false.
