Technical data for this type of fractal : click here (JMC-A01-01).

Parameters used here :
fn1() = cos(), fn2() = tan()
real(p1) = 1, imag(p1) = 1.5, real(p2) = 0.4, imag(p2) = 0.5, real(p3) = 0, imag(p3) = 0

Below is drawn the above fractal with five different palettes of colors.











Using a larger area, we can see that the initial image belongs to a pair of two counterclockwise spirals shown below.



The fractals shown above belong to an alignment along the x axis of the same images (with a pair of two large spirals).
The length of this alignment is infinite.
Below is shown a partial view of the alignment of these images along the x axis.
