Proof: Also known as

Some authors use the term sound argument as a synonym for what is defined here as a proof.

However, as some use sound argument to mean the same thing that is defined here as a valid argument, it is recommended that this term not be used.

Some authors refer to a proof as a derivation, but that term already has connotations from calculus, so it is preferred not to be used.
