Preben Alsholm now i take another dynamical system , i found 2 critical points , which one is saddle and other one has too involved eigenvalues , but didn't know how to plot the digrams you did in the worksheet ! i dont know how to define seq() .


Thanks in advance


Dear Markiyan Hirnyk 

From  Phase-space trajectories i mean below photo which the asterisk arecritical points. but how can i compute the critical points and their nature ( stable , unstable , saddle) with maple ?

Thank for your time



How to plot a dynamical system as x' = f(x,y,z) , y'=g(x,y,z) . z'=h(x,y,z) ?



e.g.    x'=(x z )/y - x - 1


         y'=x y - 5 x z + y


         z'=( x z^3 )/y+( z^2)/y+6z





I have 5 term which each term includes three function of time (autonomous system ), i want to obtain time derivative of each term as other terms for example if i define each term as a dimensionless variable , e.g.  x , y , z , v , w , i want to know dx/dt = as  x , y , z , v , w.



i differentiate each term but i dont know how to obtain each differentiated term as other terms
