Yes the formula is not random, but how  differentiate a real random 
sequence and a pseudo-random sequence like mine? I actually try to study 
this mathematicals phenomenons.
In fact, while I was looking for formulas like Lorenz Butterfly, I was 
surprised by the drawing of the formula I wrote. As I have already said 
I have not enough mathematical knowledges, but I know a little what is a 
brownian motion, and the act of obtaining this /randomness/ curves with 
non random calculations intrigue me.
