No one on this Earth can teach like this man. Knowing something and having the ability to 'teach' that something , even to a lay person, is as rare as hens teeth. He is truly one of a kind , A million thanks Professor Leonard.

Do not be intimidated by the long videos, It will be the only and last video you will have to watch about the topic. It will save you more time in the end. I was struggling so badly in so many of classes because I just find my professors go too fast or use notations that are confusing or unclear. However, after watching Professor Leonard I feel like I finally have a chance in my DE class. THANK YOU so much, actually a life saver.

I mastered those topics so well that I used to teach most of my classmates and whenever they were having trouble and recommended them to watch your videos. You deserve a NOBEL prize in teaching !!!! I need a teacher like you in every course or I wish you were my university professor.

I have probably mentioned this before in comments on Professor Leonard's KZitem channel: PLEASE support this guy on Patreon. I do. And will continue to support him. Not only is he a brilliant mathematician, but he knows how to convey ideas in a way that makes the "light bulb" come on for folks languishing in despair from college math courses. He'll probably kick my butt from saying this... Leonard has his Masters in math, but not a pHd. He wants to pursue a doctorate in Education so he can reach more folks doing their undergrad work. That, to me, is SO commendable! So PLEASE! Support Professor Leonard in anyway you can.

Method of Undetermined Coefficients for non-homogeneous equations 2. Variation of Parameter method for non-homogeneous equations 3. Second order homogeneous and non-homogeneous Cauchy-Euler differential equations 4. Power Series: Taylor and Maclaurin Series 5. Laplace Transform 6. Numerical Methods (Runge-Kutta method)

Its one thing being an excellent mathematician, it's another thing to be an excellent mathematics teacher. An excellent mathematician produces a limited number of models during a lifetime and an excellent mathematics teacher produces a generation, mathematicians for now and the future. The difference is EXPONENTIAL. prof Leonard, is perhaps one of the best maths teaching experts ever. Prof Leonard, you are doing an amazing job. Absolutely fantastic.

@@ProfessorLeonard I did not, teacher :( Sorry for the long message, but I considered it relevant to tell you, thank you It was really simple .. I understood more or less well what I had to do. The problem was that my teacher put a really long first exercise that I consider difficult (3y^2/x^2+3x)dx + (2yln(5x/x+3))+3seny)dy = 0, I took more or less 40 minutes doing that and I did not do the others, I failed in the parts of the partial derivatives because of the time :s , I got nervous and one thing led to another.. :s If I had avoided giving the first one so much time and had continued with the other 3 exercises (which I could really solve more calmly) I could have had more time and calm to solve the first one. I still expect my note. Even though I'm really sad, I'm happy with my performance.. I do understand the concepts (mostly because of you).. so THANK YOU :D . Pdt: Is there any video on your channel of only partial derivatives? I want to improve my weaknesses

Professor, you are an inspiration to many of us. I'm an applied math major and I have been struggling throughout college in my math courses. I've read many different books about differential equations, and I've watched other professors teach it, but none of them compare to how well you teach. Truly you motivate me to work harder and the only thing I wish for was that you were my professor for all of my math classes. It would truly make math so much more enjoyable. Thanks again and I hope to see more videos from you in the future.
