There are no references/citations in this article.

It would be nice if someone more knowledgeable than I could include references to some further reading materials, specifically ones demonstrating a proof of this theorem. It's a commonly known tool however without sources this result may seem somewhat mysterious to a reader. PhysicsSean (talk) 21:57, 15 May 2018 (UTC)
