Complex Fibonacci Numbers?

Huge thanks to Jane Street! https://www.janestreet.com/join-jane-... Check out Ben Sparks's GeoGebra files. Binet formula 2D complex output: https://www.geogebra.org/m/twvvzpga 3D imaginary output of Binet formula: https://www.geogebra.org/m/z6dy9cj5 3D plot of absolute output of Binet formula: https://www.geogebra.org/m/pb7hmxyd My four-part series on Numberphile videos about Fibonacci Numbers (from 2014) starts here.    • Brady Numbers - Numberphile   Here is me going on about the square root of five (Numberphile 2018).    • Lucas Numbers and Root 5 - Numberphile   This was the Fibonacci puzzle video from Matt Parker's Maths Puzzles.    • MPMP: The 1 Million Bank Balance puzzle   Read a whole bunch about "Generalized Fibonacci Sequences and Binet-Fibonacci Curves". https://arxiv.org/pdf/1707.09151.pdf The zero I found was at -9.14202391817 + 2.80064954276i and you can see the exact form here: https://www.wolframalpha.com/input/?i... Try it for yourself and put the Binet Formula (((1+sqrt(5))/2)^n - ((1-sqrt(5))/2)^n)/sqrt(5) in the Wolfram roots calculator: https://www.wolframalpha.com/widgets/... This site has everything you'll ever need to know about Fibonacci Numbers. http://www.maths.surrey.ac.uk/hosted-...

Here they all are: I misspoke around 01:13 when I said "negative one, zero" as it is clearly "negative one, one, zero". At 07:53 I mean the negative values -5 to 0. I said it a weird way. My language at about the 1D input to 2D plot from 09:17 is a bit sloppy. The real values going into the Binet function are not the horizontal axis shown; the plot onscreen is solely the output. I say "axis" when I mean "plane" or even "complex plane". The big flat thing. Let me know if you spot anything else!
