The mathematical Golden Spiral or Phi Spiral should mimic nature.
And this is what a Golden Spiral or Phi Spiral really should look like.
These are the formulas used in the calculation of the plotting:
Values for Theta in degrees:
(-2400, -2390, -2380... Zero, 10,20...1430, 1440)
r = Phi ^ (theta / 360)
Sine = SIN(Theta*Real_Pi/180) <== this is the true way
Cosine = COS(Theta*Real_Pi/180)
Corroborated the above values, all the way through with: '=sin^2(theta)+cos^2(theta) = 1
Plot points:
x = r * Cosine(Theta) as calculated above
y = r * Sine(Theta) as as calculated above
Extrapolated in the minus(deg) for Theta, that is, below or beyond zero, so you can see the
