This vid helped😭 this is a night before my engineering maths exams😭😭
I wish you success 🥺
😂 I hope you passed, mine is tomorrow 😅.
Thank you very much for this sir. Thank God I stumbled on this video.
You're welcome
God bless boss this really helped my understanding of this topic 🙏🏼🙏🏼🙏🏼🙏🏼
Amen
scrolling down very videos finally reached :) great work
Thanks
if i had you as my lecturer my maths skill would have been a lot better
You can still get better.
You're welcome to my channel.
I tell you
God bless you mentor 🙏💯💡 I couldn't understand anything about fourier series, non of my friends could put me through and my lecturer gave us this particular fourier series as an assignments God bless you sir am glad to have an encounter with you
Amen.
You're welcome.
I'm happy that I could help.
Very detailed. Thank you. I was reading from textbook but couldn’t understand 😂
You are welcome 😊
Please don’t stop making these videos 🙏🏼 Thank you
Ok Sir, I'll definitely continue.
From Tomorrow evening, back to Back.
This was beautiful very well explained, on each and every point assuming the learner doesn't know anything.... This was very insightful
Thank you 😊
How ever I don't understand on how the formula changes period like wen the function is f(x+2π) and when the function is f(x + 6) the Fourier formula changes on the period...I don't understand how they are deriving a new period
Bro your videos save lives men.... see as you just broke down this thing.. Thank you
You're Welcome ☺️
Thanks for your videos sir. It helped me pass my exams last semester
You're Welcome 😊
You videos are indeed helpful to us as students please keep doing more ✊🏾
Thanks, I'll make More.

I will look forward to seeing more videos from you in other engineering mathematics topics
Thanks
You're welcome 😊
Great video, would love to see more videos about Fourier series. 🤲
Already in Process sir.
Seriously, thumbs up sir 👏
Thanks a great deal for the fantastic delivery of this topic. Could you also add Convergence of Fourier Series with all those continuous and jump discontinuity etc?
Yeah, I would make videos on that. They'll be on my new channel. I lost my monetisation on this channel.
@@AVITECHNOLOGIES. Oh sad. What is your new channel please?
@judem433 Avitech Maths.
There's no video there yet. But I'll soon start uploading videos and drop a video on this channel to notify my subscribers on this channel.
It keeps getting better. Thank you Sir
I'm grateful.
The ministry is moving gradually 😅
I can tell you used KA stroud. Bro you're just too good sha. Agba 5.1 cgpa

yho you just saved my semester. i cant thank you enough
You're welcome.
I really like ur teaching skills ❤
Thank you for the indept analysis, I was about giving up when I met this channel. More grace to forge ahead. Please do you have videos on Bessel functions?
I'm indeed grateful.
For Bessel Functions, I don't have a video on it. I will add it to the list of videos that I will make this month.
Thank you.
I almost gave up too 😂…great job sir🥰
Thank you so much
So helpful
You're welcome
Wow...thank you....effortless brilliance
You're welcome 😊
Very helpful, I found it last semester, but this semester I have another course that requires Fourier, so I tried to check this video for the last two days, but couldn't get till today. I found it the most understandable Fourier videos on the CZcams.
This comment made my day. I'm grateful
Thank you very much for making it much more easier.
Please just a soft suggestion.
Can the videos be numbered to know the order of the teaching sir
You're welcome 😊
To get an orderly arrangement of videos, use my playlist for a particular topic. On a playlist, it's well arranged, you'll know videos you've watched and the Next you need to watch.

This haa made fourier functions look simple
"That's Madness"😂😂. Nice Tutorial Bro😎😎
Thanks Chief 😂✅
Keep the good work alive
Thank you very much.
Please keep up WITH YOUR GREAT JOB SIR
I'll do just that 😊
Thank you.
Forgot to tell you that you got me an A Legit. but I’m doing it again this semester so I came back😊
I'm so happy to know this, it's good to have you back 😊
Very clear and rich step by step explanations. Very motivating. Very well done and do keep it up. But can try to get a closed form of the series after the first term? Do have a go at it. Thanks.
That's useful Video. Thanks so much
Thanks for the impact
You're welcome 😊
You have saved a life sir
I'm glad that I could 😊
Thanks a lot ❤
You're welcome
One more thing. Please include thank you Button on us CZcams.some of us could contribute for inks used.😊 most CZcamsrs have.thanks very very much.

Good explaining,
Go ahead man
Thanks.
You're such a genius 🤩🎉😂
Thanks 😊
This was very helpful to me
Where have you been all these while
CZcams has been hiding the video 😂
Thanks for the explicit explanation sir
Bro you badd😂❤❤
😂😂😂😂😂
Omo e good die
You're amazing
Thanks 😊
Please can do a video on bounded variation 😢 and Riemann steljes integral?
I will have to study it extensively first, I have no idea about the subject matter at the moment.
Grate work sir
Sir Please I realized that you used a period of pi for the a0. Can you please explain why?
I didn't use the period of π. The distance from -π to π is equal to 2π. The period is 2π.
Thank you so much for your help 😊
You're welcome, the pleasure is mine.
@AVITECHNOLOGIES
very detail thank you very much sir.
good job loui
Thank you 🙌🙌
Good morning
@@bismarkdblaq4398 good morning
please, is there a video you did on introduction to Fourier series or where you started it from EEE231
Yes, I have a playlist that covers an introduction for Fourier Series. Here's the playlist.
Fourier Series & Periodic Function | Problems And Exam Solutions: czcams.com/play/PLyIQ6tJ1a5bajJUe52S3qzli2PwZgcjw8.html
Thanks.
@@AVITECHNOLOGIES Thank you very much
Thank you for the video , please i got confuse about a0 = 1/L and you said that L = period /2 which means pi/2 is our L but instead you use ao = 1/ pi instead of 2 / pi
The period is 2π.
The function is from - π to + π, hence, the period from minus π to π is 2π.
L = 2π/2 = π . Therefore, a0 = 1/L = 1/π.
You're welcome 😊
if the variation between pi/2 and -pi/2 equivalent to half of cercle not rectagle the same of this video, how do we do.
I don't understand what you are trying to say, but I'm certain that you're talking of something I've made a video on. Watch the video I made on Fourier series marathon, Question 7 should be similar, but I used -π to π. I have already started how - π/2 behaves with sinnx and cosnx, so that should aid your understanding.
czcams.com/video/7qxa5QOQED0/video.htmlsi=hQyxd8jg-OVSRFOj
Question 7, f(theta) = theta²
@@AVITECHNOLOGIES pls sir, I need help on this question find the Fourier series representation of x-x² from -π to π
Much respect
God i get engineering maths this morning 😭😭😭
I wish you success.
@@AVITECHNOLOGIES the fact that this exact question came out. Thank you very much for this video.
I couldn't find your video on fourier transform
I don't actually have much on Fourier Transform; here's what I have.
1st: czcams.com/video/RP-X4zbu3v0/video.html
2nd: czcams.com/video/0o4KaRXRW0Q/video.html
I noticed you making use of 1/π as start of each formula excluding T which is the period and W, which is part of the formula. For a•, an and bn.
What I know of the formula as a•=1/T integral of f(t) dt.
an=2/T integral of cosnwt dt
bn= 2/T integral of sinnwt dt
My question now is why did you exclude the w and made use of 1/π through out the formula. I will greatly appreciate your feedback, thanks
The period is 2π.
I have already simplified it with An and Bn. As for A0, the final formula I used for Fourier series is having the division by 2.
Everything is correct, it's just a mix of how I love my formulas to be.
I will look for a video for you.
czcams.com/video/BSEN9GhdDRE/video.html
Here's a video that will help you.
Please how do I know when the series is odd or even?

Wow, I really enjoyed your class sir, sir am having challenges solving this question pls can you help me out.
Find the Fourier series representation of
X- X² from -π to π
Thanks you sir.
How can I get to you directly sir? Either via whatsap sir? 🤲🙇. Thank you so much for all you do.

If I differentiate nx and it is giving me n, please sir why are we writing it as 1/n
That's the rule of integration.
If you integrate sin(nx), your result is - cos(nx) divided by n. You will have to divide by the derivative of nx. If you integrate cos4x, your result is sin4x divided by 4.
SHARP EXPLANATIONS.
Thanks Boss
Is the integral for a_0 not 1/2pi...?
Depends on what your Fourier series expansion formula is. As for me, my formula for Fourier Series has a0/2. Hence, when writing the individual formula for a0, I don't need to put over 2 at the denominator.
Here's a video regarding my derivation: czcams.com/video/w6MXI7dkwTE/video.htmlsi=OV_dMTxkwmVpoP6F

Thank you.
Thank you, got it. Great work@@AVITECHNOLOGIES
Why your voice change 😅
Did it change?
I did not notice.
😢pls sir your WhatsApp number,I have a question ,I saw one forier series questions which I don't understand the word bcos is a continuous function no need to start from 0 to 2pi nd they did not double the a0
Okay. Check my about section on CZcams to see options that will lead you to chat me on WhatsApp.
Very detailed. Thank you. I was reading from textbook but couldn’t understand 😂
You are welcome sir.
