1. The problem statement, all variables and given/known data For the following dynamical system in the attached picture What is the appropriate way to specify the equation is invariant? Thanks in advance. 2. Relevant equations No relevant equations 3. The attempt at a solution Firstly I integrated each of the three equations and the results x = 10yt - 10xt- -① y = rxt - yt - xzt -② z = xyt - 8/3(zt) -③ From equation ③, I got z = (txy)/ (1 + 8/3t) and then, I substitute the equation of z into the equation ②. Until this point, am I doing it right?
