Question: Portrait phase for coupled oscillators. Odeplot for system.


I'm trying to make a phase portrait for coupled oscillators. No problem for the following lines

Now, i want to trace x1'(t) vs x1(t) or x'2(t) vs x2(t) but i can't use odeplot. Perhaps it's possible but i can use it only for one ode.

I suppose this problem is quite simple but i'm beginner in maple

Thanks for solution
