just go this video recommended, and you're an extremely good teach, why? because I've never learned differential equations, and it still made snese. You explain these topics in such a good way, that even me, someone who has no clue in this subject can follow along and understand everystep. You state theorms so well and clear that I went like 'obviously, you reduce it to an auxilary form' when I've never heard that before. Kudos, and keep up the good work man!
This is great. I was just thinking about differential operators, and since I forgot everything from linear algebra, I’m glad I found this fantastic video that breaks it all down!
By far the best explanation of this topic I could find. Unlike other videos you actually explain it very well and now I feel like I can solve any homework or exam problem because I understand it conceptually. Thank you for this video
im 2:33 in and i just now realised that this dude is writing mirrored AMD readable while explaining it. god damn thats impressive, especially since my handwriting isnt even legible when writing normally.
That's very nice but my confusion is what we are doing after finding a eigen function.it should be satisfy orthogonal property or orthonormal........???
Great work, though i have an issue, at 6:31, you said that lamda is posivitive, right, then i guess you should have ( r squared - lamda) not (r squared + lamda) because ( lamda = + r-squared)
R sqaured + lambda comes via the auxiliary equations will not change for a particular equation , in this case y’’ + lambda y, where the auxiliary eqn would be r2 + lambda
At 5:10: I don't understand what you meant when you said "Both these terms are not equal to zero but I have things multiplied that are equal to zero." Which ultimately results in C1 equaling to zero. Can you clarify this part? I'm still confused.
Akila Kavisinghe that’s right! And since I have a product equalling 0, one of them must be 0. (The only possible choice being C1 = 0) I hope this video helped you out!
Ive thought about this a lot, im pretty sure the camera flips left to right. So he writes so it looks right to him, it looks like the mirror image on our side of the glass and then the camera mirrors the mirror image, making it look right to us.
Well that really depends on what you want the independent variable to be. Whether you use t or x is pretty arbitrary from a pure mathematical standpoint cause they are just symbols we attach to help us describe y being changed with respect to this variable at the end of the day. It doesn't really matter as long as you stay consistent with your math. It only really matters if you are talking from a physics standpoint and usually you would use t cause most of the time, time is your independent variable.
Man you out here saving student lives like its NOBODY's business
Helping students save themselves :)
The fact that he’s still hearting comments shows that he really cares
I try to keep up with the comments. Thanks for watching!

Brilliant, finally found a channel that isn't attempting to be as deadpan as humanely possible. Thanks.
Thanks very much! Have a great day.
Loved the innovative way of writing on the glass. Informative and helped me for my exams!
Thank you brother. May all your descendants be blessed
my guy is giving off some evil genius energy. Thanks for the help
😈
My man, you did a great job here. Extremely clear explanation. Keep it up!
Thanks very much!
This is great. I was just thinking about differential operators, and since I forgot everything from linear algebra, I’m glad I found this fantastic video that breaks it all down!
you just gave 15 points in my exam tonight....thank you
Glad to hear it! Hope it went well.
By far the best explanation of this topic I could find. Unlike other videos you actually explain it very well and now I feel like I can solve any homework or exam problem because I understand it conceptually. Thank you for this video
What a wonderful explanation my boss ....I love you...love from India.. you save my life..🥰🥰
Very glad to help. Have a wonderful day!
this guys is the best teacher for this problem
Thank you very much!
I never comment, but honestly bro the way you explain concepts are perfect. Keep it up!:)
Thanks, will do! Hope you have a nice day.
My exam is coming up tomorrow,you just saved my butt
The only clear explanation I could find! Thank you so much!!!
You're very welcome, glad to help!
Very Helpful!
Amazing video!
take a shot whenever he says 'zero'
Saved my ass in advanced fourier analysis, dude. Thank you!
I have my last calculus exam tomorrow and this is a lifesaver, thank you!
thankyou soo much, you save my life now.. ur explanation makes it soo easy.. am studying for my xams n this helps me a lot.. thankyou soo much
Very glad to help. Best of luck with your exams!
I have been failing all semester & now I finally understand! thank you
Glad to hear it! Best of luck
im 2:33 in and i just now realised that this dude is writing mirrored AMD readable while explaining it. god damn thats impressive, especially since my handwriting isnt even legible when writing normally.
Very well explained Brian, thank you.
I like the way you explain, also the way you move your mouth is so entertaining
Got awesome help for tomorrow's exam, thank you!
Best of luck!
thanks man! I had troubles understanding this for a while since my profs dont really explain much but now I got it!
Glad it helped!
at 2:30 you make lambda less than 0, but then define the characteristic polynomial as r^2 + lambda = 0. Wouldn't it be r^2 - lambda = 0?
No, he's substituting lambda in, not minus lambda. He's saying lambda is a minus, not that lambda is being multiplied by a minus.
thank you for such a clear and concise video!
You're welcome. Have a great day!
brah, 1:25 min you already explained everything that my lecture couldn't explain in 50 minutes.
You explained very well and really helpful.
Thanks bro...u explain very calmly that's make us understand...👍
Welcome 👍
Thank you very much Brian!
Absolutely brilliant, thank you!!
You're very welcome!
Thank you so much! This was very helpful
Very good explaination !! Thank you very much!
You’re welcome. Have a nice day!
life saver my man, thank you
You’re welcome!
Thank you for this!
thank you but how the hell do you write backwards so well???
I think he's right handed
Are you joking?
thank for your video,this really help me a lot
Glad to hear that!
Great video, i like how you explain every step
Dude this is an awesome video!!!
I really appreciate you saying so! Have an great day!
Reverse writing skills > reverse driving skills
That's very nice but my confusion is what we are doing after finding a eigen function.it should be satisfy orthogonal property or orthonormal........???
I had a test today and I think this just saved me
Great to hear!
thanks so much man, just subscribed!
You're very welcome. Thank you!
You are EXQUISITE! Thanks a bunch!
Thank youuuuuu so much!!
Thank you so much.
Great work, though i have an issue, at 6:31, you said that lamda is posivitive, right, then i guess you should have ( r squared - lamda) not (r squared + lamda) because ( lamda = + r-squared)
R sqaured + lambda comes via the auxiliary equations will not change for a particular equation , in this case y’’ + lambda y, where the auxiliary eqn would be r2 + lambda
thank you so much. It was very clear.
thanks alot it helped in my exam today
Thanks Man your a life saver
Happy to help!
Great video, best one I found!
Great to hear!
Well explained. Thank you.
You’re welcome!
This is a great explaination!
Thanks very much!
You are a lifesaver
Glad to help!
Thank you so much! This was really helpful :D
You're very welcome!
❤️loved it!!!
Thank you very much!
brilliant thanks
Thank you so much!!
You’re very welcome!
thank you
this was really good, nice
Thanks very much!
thanks for saving my final tomorrow
Best of luck!
Thank you! Explained very well
The fact that he explained this writing backwards is wild
I wish I was that talented, video editing is that wild :)
mirrored video my guy
What if i had the equation like x^2y" + λy = 0....n my λ= 1/4 for some base condition
for the same thing my professor took an our great content much needed
6:50, we only use the positive root?
great explanation
Glad you think so!
How do you do it for non zero dirichlet conditions?
I’ve been looking everywhere
Thanks a lot
You’re welcome! Have a nice day.
Nice lecture. It turns up in a Google search, but I don't see it listed in the channel. Why not? Are there other good lectures I don't see?
hi is there a quick check to see if the ode will be an eigenvalue problem?
Is there an organized list of these Brithemathguy lectures? Google brings up a large disorganized list.
thank you.
Why can we assume an exponential solution? It feels like a cop-out that there is no way to know for certain besides by inspection.
Hi! For the lamba
What is the significance of eigen value in heat equations?
At 5:10: I don't understand what you meant when you said "Both these terms are not equal to zero but I have things multiplied that are equal to zero." Which ultimately results in C1 equaling to zero. Can you clarify this part? I'm still confused.
Oh I get it now since the right side HAS to equal zero due to the initial value!
Akila Kavisinghe that’s right! And since I have a product equalling 0, one of them must be 0. (The only possible choice being C1 = 0) I hope this video helped you out!
thanks
You’re welcome!
Kindly explain on the boundary Conditions,
kindly if possible,, explain the meaning of the letters,c2 etc and kindly shed more light on the conditions,,
@@derrickerrick3370 c1 and c2 are arbitrary constants
Why is the solution different whether you set λ=0 before or after you solve the general case of y''+λy=0?
Gracias por tanto ❤
Glad you enjoyed it!
Hi, the video is intriguing, however, I am interested in the way you write one the board, how can you do that
Hey where can i get more of these questions?
you literary saved me .................
Very Slick the 2n+1 thing Nice! 🙂
Oh yeah!
How do you write laterally inverted? Is it some editing or you are actually writing it inverted.
It is through the magic of video editing :)
i think a "mirror" will do the trick easily. btw, tis a great presentation!!!
Mirror Writing... Lol
Just flip the screen after recording easy
respect for writing all that backward
Ive thought about this a lot, im pretty sure the camera flips left to right. So he writes so it looks right to him, it looks like the mirror image on our side of the glass and then the camera mirrors the mirror image, making it look right to us.
What if the conditions were y(0) = y(2 pi), dy/dx(0)=dy/dx(2 pi), what would the Eigen Values & Function be?
thats why he's..... THE GOAT, THE GOOAAAAATTTTTT
Nice video! I thought you'll add up all the solutions tho
I assume Cn changes for every value of n ?
For lambda
Are u sure?
i have exam tomorrow if you gimme the right answer i will solved this information
How is he able to write in reverse order so fluently??
thank you very much!. im from chile.
You are welcome!
Why don’t you have to solve for C2
y prime denotes dy/dx so the use of t is wrong, it should b x
Well that really depends on what you want the independent variable to be. Whether you use t or x is pretty arbitrary from a pure mathematical standpoint cause they are just symbols we attach to help us describe y being changed with respect to this variable at the end of the day. It doesn't really matter as long as you stay consistent with your math. It only really matters if you are talking from a physics standpoint and usually you would use t cause most of the time, time is your independent variable.
