Introduction

In the realm of propositional logic, truth tables are a fundamental tool used to evaluate the truth values of compound statements. These tables provide a systematic way to determine the truth values of statements based on the truth values of their constituent parts. In this article, we will delve into the world of truth tables and complete a given table using the statements $p$ and $q$. We will also explore the concepts of conjunction ($\wedge$) and disjunction ($\vee$) in propositional logic.

Understanding Propositional Logic

Propositional logic is a branch of mathematics that deals with the study of statements that can be either true or false. These statements are called propositions, and they can be combined using logical operators to form more complex statements. The two main logical operators used in propositional logic are conjunction ($\wedge$) and disjunction ($\vee$).

• Conjunction ($\wedge$): The conjunction of two statements $p$ and $q$ is denoted by $p \wedge q$. It is true only if both $p$ and $q$ are true.
• Disjunction ($\vee$): The disjunction of two statements $p$ and $q$ is denoted by $p \vee q$. It is true if either $p$ or $q$ (or both) is true.

The Given Truth Table

The given truth table is as follows:

$p$	$q$	$p \wedge q$	$p \vee q$
T
	T

Completing the Truth Table

To complete the truth table, we need to determine the truth values of $p \wedge q$ and $p \vee q$ for each possible combination of truth values of $p$ and $q$. The truth table for $p \wedge q$ is as follows:

$p$	$q$	$p \wedge q$
T	T	T
T	F	F
F	T	F
F	F	F

The truth table for $p \vee q$ is as follows:

$p$	$q$	$p \vee q$
T	T	T
T	F	T
F	T	T
F	F	F

Analyzing the Truth Table

From the completed truth table, we can see that:

• The conjunction $p \wedge q$ is true only if both $p$ and $q$ are true.
• The disjunction $p \vee q$ is true if either $p$ or $q$ (or both) is true.

Conclusion

In this article, we completed a given truth table using the statements $p$ and $q$. We also explored the concepts of conjunction ($\wedge$) and disjunction ($\vee$) in propositional logic. The truth table provides a systematic way to determine the truth values of compound statements based on the truth values of their constituent parts. Understanding the basics of propositional logic and truth tables is essential for any student of mathematics and computer science.
