WebThe golden ratio is an irrational number. Below are two short proofs of irrationality: Contradiction from an expression in lowest terms. If ... Exceptionally, the golden ratio is equal to the limit of the ratios of … WebSep 13, 2024 · In a previous example, 1 / ϕ = ϕ − 1 where ϕ is the golden ratio 5 + 1 2. Since I am proving by contradiction, I started out by assuming that ϕ is rational. Then, by definition, there exists a, b such that ϕ = a / b. After some simple calculations and using the result shown from my previous example, I found that ϕ = b / ( a − b).
