These lectures are of great quality and cost me nothing. Thanks to your efforts prof. You are helping many students who either can't afford quality maths education or sometimes have no access to quality education even if they pay.

I am suffering from the second. My professors aren't bad, but they don't want to put in the effort after looking how mediocre the rest of my class is, so I have to suffer because of it too

I swear this channel explains stuff 10x better than my university's lecture videos actual livesafer

Dr. Trefor Bazett, thank you! After 9 years off maths and going back in to doing a Masters in Engineering this channel has been an absolute blessing. You deserve some serious recognition!

I love how even behind a screen you are aiming at teaching the topics by ensuring that your students grasp them, thanks sir

Haven't seen anyone delivering the concepts of ODE's better than this . Remarkable methodology.

I finally understand why any particular solution will work. Thanks! You always make material clear and engaging.

This was a great refresher to ODEs. Thanks Dr. Trefor for the wonderful series.

Literally Dr. Trefor, you are the best to help understand mathematics. The beauty of mathematics comes out in your videos!! I am going to make a daily schedule to listen to your videos. Thank you Sir.

Really refreshing to feel some enthusiasm while teaching and not just a monotone voice all along. Thanks !

Did differential equations 20 or 25 years ago. Make sense watching it 2x speed non-stop. Thank you.

I spent over 10 hours trying to understand this from my school lectures and it only took 13 mins on here. Thanks a lot Trefor, at least I won't be clueless in my exam tomorrow

Thank you so much for your videos! They helped me greatly in passing Differential Equations and made a lot of things that were confusing in lectures really clear and concise! Couldn't have gotten the grade that I did without your extra help.

Professor Trefor Bazett, thank you for an outstanding video/lecture on Undetermined Coefficients in Ordinary Differential Equations.

The quality of education you are providing is just amazing :) Very helpful , Thank You 🧡

Such crisp presentation! Finally was able to complete my syllabus for ODEs and Lin Algebra

You are so so talented at lecturing. Thank you for putting these together!

Thank you so much for the video! I watched it last year when I took intro to differential equations, and I'm watching it again this year as review for my engineering analysis class. Your explanations are perfect!

I never really understood why add Complementary Function and Particular Integral but now I do Thanks for clearing a basic concept

Finally you received after your 7 years of hardwork congrats for 100k

This video about solving linear non homogeneous ODE's is the best on the internet in my opinion, thank you!

Thank you so much. I wish my proffesor explained with the joy you explain. I'll let you know if I pass my exam in 2 hours

Love this guy, I’ve been confused for a week but not anymore

I taught I will just watch it and leave it but I found it a great video by great lecturer I need to download it fast.❤ U are too good sir

Was super confused on this after my lecture. This helped clear it up. Thanks king 👑!!

And, once again, Trefor managed to make sense of a week worth of lectures in under 13 minuits

I have an ensuing test on this and variation of parameters and these videos are very helpful! Thank you!

I have a midterm in two days, and your videos are saving my life!

Thank you for this series of videos. They help me a lot when trying to study ODEs on my own. Also, the visualizations are very good. I hope there'll be more videos concerning the applications of these equations in real physical cases, like those about mechanical vibrations. After all, thank you for all your works!

Thank you so much Dr. Trefor!

youre the goat bro my prof is a professional yapper and what you explained in 12 minutes takes him two 50 minute classes

Your videos are wonderful, can't thank you enough

you are a lifesaver, ty Dr. Trefor~

thank you so much for this lecture , it is helping me more for my preparation ,thanks again

Good job. I don't remember it being this easy but it looks easy now.

The variation of parameters is more convincing and more general method than undetermined coefficients.

It is a really good video, the part which I love so much is the chart part. But I have a question, how to deal the particular solution equation like tcos(t)

This is super helpful, thank you

man you are a gold mine

very good explanation

Best video I’ve seen on this

Great explanation❤❤

Very good video thank you!

incredible lesson

Thank you so much for the nice videos, it is really helpful. Right now I am having a problem with the following form: (dv/dt + L1*v = L2*(dx/dt+L3*x)), where t is the time variable, L1, L2, and L3 are constants, dv/dt, and dx/dt are the rate of change of v and x w.r.t time respectively. Is there a possibility to solve it without using Laplace? Is there a generic method to solve similar kinds of problems?

you're a live saver man

that was really helpful!!!

Hi, thank you for the videos, helped me a lot. In the guesses (9:17), the multiplicity shouldn't apply?

open source textbook? mvp

Very helpful!!!

Very thank you respected sir...

that was so helpful thanks

Thanks Dr. It was difficult before I storm this youtube video

Ex. 2 highlights the fact that the pieces of the general solution must be linearly independent.

Thank you so much sir

thank you for this video sir

Hello Dr. Thanks for the lectures, they are really helping to me. I have the ff differential equations and need some ideas on how to start: solve a) x''=-4x^3+4x , b) y''=y^2-y?. Thanks.

You are a legend my friend

Thank you very much sir 🔥🔥🔥

Thank you ! 👌

First off thank you so much for these videos they’re helping me tremendously. I had a question not super related to this video, but we’re learning variation of parameters right now. Do you have any materials that would help with that or a different way to do questions that ask you to solve using variation of parameters? I’ve looked at other videos and they make some sense but the explanation is too fast and steps are glossed over without explanations.

Aha! I didn't realise that any 2 particular solutions would differ by at most some y_h, that makes so much sense. Finally I can do some well-justified guesswork.

I LOVE THIS MAN

@1:18 by this logic, wouldn’t y_p + an infinite sum of y_h also be a solution? Since y_h will all end up being 0

Thank you!

Hey Trefor! I have got a question that I can find no answer to and since you are a math Professor I hope you can help me. Its about partial differential equations (i know not exactly the topic of the video) in physics. My question is: How can we be sure that ,since we often can only find parts of the general solution of a pde, that this part represents the physical scenario? An example to clear things up: take for example the schrödinger equation. We usualy solve it by seperation of variables. However there are defenetly other solutions as well that are not seprable but still solve the equation, we just cant find them analitically. How can we then still make sure that the studied particle has the wave function (or one of the wave functions) that is/are given by the seprable solutions we found and not by another? Doesnt that basically destroy or chance of getting information abou the particle since the most general solutions to pdes are usualy such a wider class? Thanks in advance!

Definitely look up the various existence and uniqueness results for separable PDEs, this is what ultimately gives us a handle on the “halting problem” you describe.
