    Anyone else trudging through this journey of remote learning for a year now and fighting back tears watching this after reading his shirt? lol

    Watching these videos over the summer before my actual differential equations class starts helps so much. This world needs more people like you and PatrickJMT who can explain everything clearly instead of teachers just trying to show off how much they know.

    I've got my first dif eq exam tomorrow morning but I know I'm going to do well because Prof Leonard believes in me :)

    Right now, I'm spending my summer going through your Calculus 1 playlist, and I've enjoyed it. Thank you so much for helping me rediscover my love for math. I've done practice problems on each topic and it all makes perfect sense to me thanks to you.

    Your video does help me a lot, after I've found a dozen videos, and no one gives me a clue about what exactly the equilibrium point is. Thank you so much!

    In principal I've gone beyond this material. Watching you vid proved to me that I've never given it enough thought and I still have a lot to learn. Thank you professor, for giving me the motivation to keep studying further. Also,thank you for your efforts!

    Please continue the series professor, in any way possible! Your teaching is unmatched and would do anything in the world to get the rest of the material for DE taught under you. Wishing you and your family great health and prosperity

    Thank you professor Leonard for all your videos. They helped me succeed in Calculus 2 and Calculus 3 in college. I really enjoyed learning and watching all your lectures. They were always very interactive, especially with raising our hands :)
    I really appreciate the work you do.
    Thank you again professor.

    Sir. I just dont have words. Your teaching is just a whole other level of teaching. Domt think i have ever come across a better teacher than you. Your the reason i nailed my further calculus. And now your gonna be the reason for me to nail Mathematical Economics. Thank you sir. God Bless you and may you be blessed with the best!! ❤❤❤

    Hi Sir hope you are having great time. I have a question regarding fixed point. In context of a function fixed point is defined as f(x) = x or standard notion is T(x)=x as given by Banach fixed point theorem. But in context of dynamical system when we use the word fixed point it seems that it doesn't relate to definition T(x) = x but rather we say that fixed point is where the derivative is zero. So my question is that does the word fixed point meaning differs in both contexts or is there any analogy.

      ​@@ProfessorLeonardAwesome! Keep up the great work and congratulations on the new addition to your family!!
      I recently graduated from UC Berkeley in Physics and am preparing for grad school. Your videos are invaluable and a godsend. I just completed the entire series of differential equations so far and wrote down detailed notes of all the different techniques and examples.
      Also, thanks for the reply! Really nice actually hearing from you. You were my colleagues and my Calc 3 teacher because our teacher in community college didn't teach the material very well.
      You do such an excellent job of making difficult/higher-level concepts accessible and easy to understand and digest.
      Thank you for your time and energy and for everything you do!

  • @kaushikdr
    @kaushikdr Před 3 lety

    How can a function like (3 - x(0)) equal plus or minus C? Shouldn't it only be able to equal one of them, at most? In addition, can an initial value that starts on one side of a critical point ever jump over to the other side of the critical point; if not, why not? Your videos are pretty awesome!

  • @hollychilcott1904
    @hollychilcott1904 Před 3 lety +1

    Do you have a tee spring where we could get t-shirts like the one in this video? Or hoodies that have a cool print to look like your channel profile image? I could think of a bunch of cool designs. Like a silhouette of your hair, glasses and face, but instead of the superman "S", it could be an integral symbol inside the superman shield. So many possibilities!

    • @ProfessorLeonard

    Does anybody know if Autonomous first-order DE are the same as Equilibrium Solutions and Stability of DE?

  • @natepolidoro4565
    @natepolidoro4565 Před 5 lety

    I think that the second derivative test for relative extrema is more reliable because you only need the critical point itself to plug in. The first derivative test needs two points around it, and one point might be far enough from the crit. pt. that it will give you an inaccurate answer because the slope to the right of the crit. pt. might be positive (for example) and if you choose a pt just beyond that, it might be negative. #secondderivativetest all tha way
