just answer the question
I know ab=ba but thats all im seeing , plug in the numbers
I can't answer the question because I am new to the topic.
If dynamical systems could easily be understood with "good ol' reasoning" then why are university professors at Harvard studying them?

Oh right, youre smarter than Harvard professors who study this. Maybe you can teach them about dynamic systems with your good ol' reasoning.
