Holy cowabunga man, not sure if you recall I once said an math explanation of yours was lacking, well this is the exact opposite!!! This was sooo enlightening that I can't possibly thank you enough. And your physics videos are still the best. Thanks my man.
I am from Iraq, a student in Environmental Engineering and Pollution and I benefited from you very much. I would like to thank you and greet you for your efforts with all respect and appreciation for you😍🌚
my solution is so short but we have the same final answer! i think your solution is just so systematic so everyone can follow but anyway you're so amazing! thanks for these examples and explanations you upload :D
What if we have more than 2 variables? So for example instead of an equation that is made of dx and dy, we have an equation that is made of dx, dy and dz? Can you show any example for this?
Thank you once again for these awesome playlists (so far)! With these thousands of great videos, I don't think I can watch them all in my lifetime (due to some life pressures). I have a question In 3:13. Is there any other video that can explain more in details this principle of equating partial derivatives of M and N. Seems to me a differential within a differential thing, sort of.
because if you diff M to y and N to x and both are the same you show that the solution is "well behaved" i.e. continuous and its derivative is continuous aswell. Schwarz's theorem.
this is so confusing, All you did was take the integral of M=constant and this your answer. another video on youtube took the integral of m, differentiate m then set that equal to N. My teacher does it another way so I'm am totally confused on which way to do it
It turns out there are usually multiple ways to solve differential equations. We show you the different techniques and then you pick the one you like best. (There are many other examples in the playlists).

I looked at my textbook for an hour, wasn't getting anything, was frustrated, then came to RUclips and here you were making it easy. Thank you.
You've helped me through my engineering classes. Donated to your channel. Best teacher ever.
Thank you. Much appreciated.
im so grateful this man exists like damn lecturers dont explain this topic well but he does. thanks for the vid
Glad you found our videos! 🙂

Apart from very good explanation. I
Must also say you have clean and nice Handwriting.Thanks for
Making the videos available
Thanks and welcome

That is correct. Once you understand the basic methods, you begin to find the shortcuts.
My savior since my freshman years thanks to you 😭
Thank you Sir! Lot of love from Malaysia!
Most welcome!
This is a very beautiful way to solve exact equations ,,and l prefer this one over the method l already know honestly!!! Thank You Mr B😃😃😃
You're very welcome!
You are better than my DE professor. Good job.
If I didnt work from you I could not have a better understanding :) thanks proff
Happy to help!
You're a great teacher, thanks for the video!
so around 2:55-3:15ish, the reason why we switched the w.r.t "x or y" is to prove the M and N are equal vice versa?
That is correct.
Doing what my professor can't do, thank you
Thank you so much sir, love from India🇮🇳
Welcome to the channel!
Enjoyed it. Thanks for your wonderful videos.
Glad you enjoyed it

Thank you. Your videos are always so helpful.

I have an exam in 2 hours... thank u, 😭🌸
Best to you!
It went really well :) Thank you once again
Thank you so much for teaching!! But how did the u = x^3 - 2xy^2 + y come? Why the 2xy^2 on both sides do not have to be eliminated?
We are just comparing the two equations so we can solve for f(y) which in this case is y
But why the - 2xy^2 didn't have to add into the final equation twice? Is it correct to say u = f(x) + f(y) + the common term? Thank you.
Best and clear explanation to understand
Very helpful. You make it so easy to understand. Thank you.
Eres genial amigo un abrazo desde San Jerónimo antioquia Colombia
Welcome to the channel.
You are a mastermind.
you make my life much easier
thanks sir you are really a legend teacher
if we are doing partial derivative for Mdx+f(y), why didn't the -2y^2 go to zero since we're taking partial of x
We are taking the partial derivative with respect to y of that term.
@@MichelvanBiezen why ?
Sir what will be the meaning of the solution that you have explained in last. Means what it will do to our original equation in question kindly answer
well explained. bravo
Thank you
could tell us how which is the form of exact and homogenous differential equation please ??? how to recongnize them
Hi, i have a question, what if at the end, the f(x)=f(y), How to find its value?
Sir why We partially diff. M to y and N to x??
Why we can't partially diff. M to x and N to y???
because if you diff M to y and N to x and both are the same you show that the solution is "well behaved" i.e. continuous and its derivative is continuous aswell. Schwarz's theorem.
@@AndDiracisHisProphet, sir why we called it exact equation???
@@AndDiracisHisProphet sir is there any theorem of this method, that you use to solve this problem??
@@zohaibhassan4435
What's your background?
@@AndDiracisHisProphet sir I'm a student.
SIRRR THANKYOUU SO MUCHH!🥺😭
You are great thank you so much
Glad it helped
Thanks for the video
Our pleasure!
Great video, but. I wish you would move the camera closer to the board next time. It's too far for us glasses wearers 😔
I want to ask that what is u stand for? -(sin x+2xy^2)/(2x^2y+y cosy) ?
u is the presumed solution to the differential equation that must meet the conditions shown. Then you find the solution as shown in the video.
Hello! Can you help me in solving this differnetila equation solve y'=(y^2)-1?
el-mehdi Benchaib here is a hint- use partial fraction decomposition.
Thanks dude
Happy to help
Hi I just want to know if you are still active 🤠 pls reply me
Active in what way?
@@MichelvanBiezen ohhh my bad I thought you abandoned this channel because it's like 8 years ago ☺️
We have added at least one video every day for almost 10 years now. (There are now over 9000 videos on this channel).
@@MichelvanBiezen 😳😳😳😳😳😳 9000!!!!!!!! GREAT JOB
This is more like Michael Bambozzle
Zoom the work so that we can see well
The videos work better on a computer at full screen. Even on a phone if you can go full screen it works better.
Thank you sir
tqsm !
POV youve found the best
Glad you found our videos. 🙂
Thank you sir!
You are welcome!
thanx alot

where did the -4 came from?
He "partially" differentiated with respect to y, making 3x^2 constant [d(3x^2)=0] leaving d(-2y^2)= -4y.
this is so simple i fell asleep
Thx sir ❤
LETS GOOOOOOOOOOOOOOOOOOOO
Glad you liked it. 🙂
thank uuuu
Sir, take love from Bangladesh 🇧🇩।
Don't mind sir, may I know your birthdate please? I've searched in facebook and LinkedIn, but couldn't find 😶
We rather keep our birthdays private. Thank you.

wow wow wow thanks
