In logic, specifically in deductive reasoning, an argument is valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. [1] .

2024年8月28日 · Rules of inference are essential tools in logic and mathematics, enabling the derivation of conclusions from premises. They form the backbone of logical reasoning, and …

2018年9月9日 · In mathematical logic, satisfiability and validity are elementary concepts of semantics. A formula is satisfiable if it is possible to find an interpretation (model) that makes …

2005年7月12日 · Abstract. The purpose of this paper is to investigate the mathematical practice of proof validation—that is, the act of determining whether an argument constitutes a valid proof. …

Valid and Invalid Inferences. An important feature of valid arguments is that any instance of the form of a valid argument will also be valid. For example, consider the valid argument

2018年9月28日 · If you write $y=\sqrt{1-x^2}$ for $-1 \le x \le 1$ you have a valid function because we have restricted the $y$ values to $[0,1]$ and for any $x$ in the domain there is …
