7 years later and this is going to save me on a final!
Easily the most succinct video of any maths concept I've ever seen. Fantastic, thanks.
After a long day of searching, I found this stuff. Thanks, man. It's sufficient.
Almost 8 years later and you are still helping out people
Most simple, peaceful delivery of a sophisticated area of maths! Regards Sir.
I was very impressed with the explanations. Thank you for the knowledge sharing
you sir.. just save my semester!!! God bless you very much:)
Thank you for being so concise and eff
This literally saved my life an hour before an exam, thank you
Thank you! that helped me a lot with my study
Thanks dude, really helpful
great video!
شرح ممتاز، شكراً لك.
Thanks to this video, I understood how to do it all. Hello from Russia :)
Nicely Explained
Thanks
Thank you!
Thank you so much, you helped me^^
Thank you so much for this. My prof skips almost every step and assumes that it is common sense to be able to deduce this stuff
me too😢
You're a god. Holy shit thank you for this video.
Please professor video for
Nonlinear fixed point stability and the Jacobian matrix four dimensions
I really need a video of four equations with four variables
Why did you calculate the eigenvalues for last equilibrium points but not the first 3?
Please professor video for Nonlinear analysis fixed point stability and the Jacobian matrix four dimensions

Good video. I have a question .
Would you help me with this system finding out if it is stable or no stable?
dot X1= 0.5-(X1)^0.5
dot X2=(X1)^0.5-(X2)^0.5
hi, what software you use for solving this question? (means writing down)
So saddle = unstable?
👍👏
What is a fixed point?
What happens if the eigenvalue of the jacobian matrix is zero
Then stability is neutral.
@@ProfJeffreyChasnov what does that mean in terms of the behaviour of the vector near the critical point?
@@blackclover4375 It circles around the critical point, not moving closer or further away.
@@ProfJeffreyChasnov I am no expert, but this sounds wrong. I believe there will be counterexamples even in dimension 1, where there is no "circling around." I think you either have to examine higher order derivatives, or look at how the Jacobian behaves in the vicinity of the fixed point.
