ab = a + ba = 1.618 = Φ (phi)
Where ‘phi’ Φ represents golden ratio.
When we divide a line into two parts so that:
the long part divided by the short part is also equal to the whole length divided by the long part.
Golden ratio, also known as the golden section, golden mean, or divine proportion, in mathematics, the irrational number (1 + Square root of√5)/2, often denoted by the Greek letter ϕ or τ, which is approximately equal to 1.618.
ab = a + bb
ab = aa + ba
ab is the Golden Ratio φ, aa=1 and ba=1φ, which gets us:
Φ(phi) = 1 + 1Φ
How to Calculate
Simple formula for the Golden Ratio
Φ(phi) = 12 + √52
