Formula & Methodology
The phi function, also known as the golden ratio, is defined as the limit of the ratio of two successive Fibonacci numbers as ‘n’ approaches infinity. The formula for calculating phi as a function of ‘n’ is:
φ(n) = (1 + √5) / 2 ≈ 1.61803
However, for practical purposes, we use the Binet’s formula:
φ(n) = (√5 + 1) / 2 * (1 + √(5 * (5 ** (n - 1)) - 4)) ** (1 / (2 * n))
