# Definition:Derivative Truth Table

## Definition

A derivative truth table is a truth table for a statement form which is not mapped by one of the fundamental truth tables:

Logical Not
Conjunction
Disjunction
Conditional
Biconditional

## Historical Note

The separate categorization of the five fundamental truth tables for the five statement forms appears in 1946: Alfred Tarski: Introduction to Logic and to the Methodology of Deductive Sciences, and may be idiosyncratic.

This treatment refers to all statement forms which are not one of these five as compound, but $\mathsf{Pr} \infty \mathsf{fWiki}$ follows the conventional view that a compound statement is any statement which involves a logical connective.

Following Tarski's lead, a derivative truth table can therefore be defined as a truth table for a compound statement.

The distinction is not an important one, but such a treatment can be useful for beginners.
