Wonderful explanation and much simpler than what I have been taught by my lecturer.

I have a differential equations final in 18 minutes. You just explained this better than 2 TAs and 2 Professors managed to in all of my time studying. Bless you bless you bless you.

here is a wonderful tip to make your life easier: the matrix will be spiraling counter clockwise if the lower left value of the matrix is positive, and clockwise if it is negative.

By far the best video on the topic I could find on the internet. I watched this when I was learning it, and now that I'm reviewing for my final tomorrow I spent a good chunk of time searching for this video specifically just because of how good it is. Thank you so much

You can easily know if its clockwise or counter clockwise by observing the the matrix A, if the element A21>A12 so it''s counter clockwise and if A21<A12 so it's clockwise, and thank you for this video.

Studied all day to find out how to sketch these portraits and you explained so well thank you. Im glad I found your video or I would still be lost.

You've made it so much simpler, now I get it. Thank you!

take a bow professor!, not many professors can share knowledge in such a lucid manner. Thank you.

best video. I've watched it multiple times while studying for my Diff Eq final

[ichigo]

thank you! this is so much more simpler and easier to understand than just reading textbooks/listening to lecturers. Keep sharing your gift!

[FullCircle]

this was actually one of the best DE videos on this topic i've found

[wippedcream]

Best explanation of phase portraits I've seen online, great video

[shadin]

Given its the season of covid, I really appreciate this. I tried to get help from my professor on our forum board but got told to rewatch the lecture. If I understood the lecture I wouldn't need to ask for help!

At 16:55 the spiral should be counterclockwise, as the -2 down to -3 shows anti-clockwise sign and rest is fine...these lectures are treat to watch!!!!
