What does the golden ratio have to do with complex hyperbola and real circle

132 Views Asked by At

If you have $xy = i $ and $x^2 + y^2 = 1$ then you get the solutions that have the golden ratio in them.

These are the solutions

Wolfram calculation: https://www.wolframalpha.com/input/?i=xy%3Di%2C+x%5E2%2By%5E2%3D1

What is exactly happening here? Why is that $-1$ in $ -1+\sqrt{5} $ instead of $+1$. Is there some spiral going on? Hopefully someone can show me what is happening here, I'm quite curious. I also don't really know how to visualise where $xy=i$ and $x^2 + y^2 =1 $ intersect.

It probably has to do with self-similarity, since that is basically the gist of the golden ratio.

The polynomial you get from those equations is $x^4 -x^2 -1 = y$, which is basically really similar to the golden ratio polynomial.

Also if you swap the constants: $x^2 + y^2 = i$ and $xy=1$, you seem to rotate the solutions wolfram calculation

Since $e$ is the hyperbolic constant and $\pi $ the circle constant, can you relate them all nicely in one equation?

Summing my questions and making them concrete:

  1. Why exactly is the golden ratio showing up here geometrically?
  2. How can you visualise what a 'complex' hyperbola and a 'real' circle is. They seem their 'conjugates' almost.
  3. Is there a way to better understand what is going on here? It is probably quite trivial but it seems very interesting.

$xy$ is basically a square that you squish and stretch while keeping the area constant. Maybe you are somehow constructing a golden square, but I don't clearly see it.

Thanks in advance!

EDIT: I still don't quite understand it, but I found this that maybe is related: Ideal triangle
