The Golden Ratio: How to derive it a+b/a=a/b=1.618..

How to Calculate the Golden Ratio - https://www.masterclass.com/articles/golden-ratio-explained#a-brief-history-of-the-golden-ratio

 https://en.wikipedia.org/wiki/Golden_spiral: In geometry, a golden spiral is a logarithmic spiral whose growth factor is φ, the golden ratio.

Fn = Fn-1 + Fn-2 where n>3 or n=3 http://jwilson.coe.uga.edu/EMT669/Student.Folders/Morris.Stephanie/EMT.669/Essay.3/Fibonacci.Essay.html

Special feature of the Golden Number is it has a similar conjugate: Golden Ratio Conjugate: 0.618..

1 / 0.618 = 1.618.. = 1 + 0.618


 

x2-x-1=0, x(x-1)=1, we get x=0 or x=1 unit circle

1.618 is one of the roots of x2-x-1=0
