Heron\u27s formula as the solution system of functional equations

Abstract

U ovome članku se do Heronove formule, za razliku od mnogih dokaza iste, dolazi netipičnim načinom i postupkom. Naime, promatrajući jedan sustav funkcijskih jednadžbi s tri realne varijable dobivamo rješenje čiji kvadratni korijen ima istovjetnu algebarsku strukturu kao i Heronova formula. Analizirajući svaku od četiri jednadžbe sustava dobivamo ne samo informacije koje nam govore da se uistinu radi o Heronovoj formuli, nego i mnogo više.In this article many non-standard methods and procedures are being used to prove Heron\u27s formula. Namely, by observing one system of functional equations with three real variables we reach a solution which square root has the same algebraic structure as the Heron\u27s formula. While analyzing each of the four equations of the system we get not only the information which confirme that the formula in question is indeed the Heron\u27s formula but much more as well
