Recently, I was trying to understand the concept of Phase diagram. I found that they are only useful in visualizing the solutions of scalar autonomous ODEs and not suitable for investigating non-autonomous ODEs. My questions are,
- Why we can use the phase diagram technique only for autonomous equations and not for non-autonomous equations?
- Is there any other method available to visualize the solutions of non-autonomous ODEs?
Please let me know for any other information. Thanks in Advance.
