Can't second that comment enough, makes you wonder why you're paying £9000 a year when you can find higher quality teaching on CZcams. Fantastic lesson
Not sure if anyone gives a shit but if you are bored like me atm then you can watch all the latest movies on InstaFlixxer. I've been binge watching with my gf for the last couple of weeks =)
That was the most comprehensive and the most simplest fourier series explanation, not just reading I have to add this, explanation. Thank you sir, God bless you.
I never thought Fourier Series was this easy and so practical the way u teach is awesome everything sounds crystal clear to me on this topic u seriously are a genius.
Thank you for this. You are very thorough and this has helped me out tremendously. Students are lucky to have you as their professor! I wish mine taught like this.
Thank you very much! This is exactly the kind of questions my professor will ask and you just taught me how to solve them so easily ! I just couldn't figure out where the (2k-1) or (2k) would come from... it's all so easy when you understand it haha Once more, thank you very much sir !
i have an habit of studying everything just a day before the exams.and on day before my maths examination i found out i had lost my notes.my friends live far off.so there was no option but to search it on the internet.fortunately i found your videos and even i was surprised to find out that i could do most of the questions.the results are not out yet but i will definately get good grades..thx a lot sir.i wish i could replace my maths professor with you
Dr. Chris you are just amazing. I have tried understanding this topic on my own but I was unsuccessful. Your explanations and the ebook has made me grasp the concept here. Thanks so much and God richly bless you and grant you more success.
you are so good at teaching this, its like you are teaching multiplication to a 3rd year math science student thats how clear and how well you explain it, thank you very very much for these videos! May i ask - what university do you lecture at? i am just curious
Dr Chris Tisdell you are wonderful gifted professor who made a difficult course easy. Your students are luckier then me and many others who are wondering of youtube to find help.
It really did. I made through the course with your videos. I believe without your videos I would have not been able to pass this class. Therefore, I can not appreciate you enough. Thank you a ton.
@xXxBoScOxXx It depends on exactly what the questions asks for. If you are asked for the "fourth partial sum" then you would sub in n=1,2,3,4 and write everything as a sum. If you are asked only for the first 4 terms, then you would do the above but write the terms like a sequence with commas between them. This is my opinion, so you'd better check with your Prof also.
thank you very much ! one question for the part 2 of the problem (proving the value to which the sum converges), we should always work with even functions right ? since A0 isnt cero, or could we have proved it just as well with the fourier series that we obtained for odd function too? Thanks !
hey, you might not read this in time but; i have what i would describe as an even function but shifted 10deg. im thinking of just substituting in x=t-10 or something to use the even simplifications. would this be an issue for later questions where i need to use the series to find the rms and THD using the first 5 harmonics. cheers
Hero! I was so lost, i didn't understand my lecturer at all but this is gold man :') thanks O can i just ask that if the questions asks for the first, say, 4 terms i just sub in n=1, n=2... and work out what the expression becomes?
why is x=0? it seems lucky that you chose that x=0 and it worked out. How do I know what value of x to use in a different question? Besides that, THANK YOU VERY MUCH!!!
I have the same question! Some textbooks say it's 1/L and then others say it's 1/2L. If you see this @Dr Chris Tisdell please help to clarify. Many thanks in advance.
@DrChrisTisdell Thanks for ur immediate replies. Ur videos are great, i think if i had watched it properly i wouldn't have posted the questions. Thanks a lot....

Learned more in two days than in two years. That feeling when you find someone who can actually explain and just not read. Thank you Dr. Chris Tisdell

@Ayaan Emerson definitely, I've been using InstaFlixxer for since november myself :D
You are the messiah for fourier series. Thank you, good sir
Wow! Thanks.
That was the most comprehensive and the most simplest fourier series explanation, not just reading I have to add this, explanation. Thank you sir, God bless you.

This is the best Fourier series video in CZcams. Thank you for your tip that bsubn of any even f(x) is 0.
I love how your cover the nitty gritty. No hand waving in the house of Tisdell.
9 years ago wow, knowledge is really timeless.....guess youtube is a time machine after all
Thank you very much! This is exactly the kind of questions my professor will ask and you just taught me how to solve them so easily !
I just couldn't figure out where the (2k-1) or (2k) would come from... it's all so easy when you understand it haha
Once more, thank you very much sir !
I pretty much never leave comments however I found this video so helpful I feel it warrants one. Awesome video, thanks.
Thanks! I hardly every leave comments, too, so I understand the significance of you giving some feedback.
Great explanations Dr. Chris. Thank you and greeting from Mexico.
I am glad you understand. There are more examples in my free ebook - the link is in the description.

Very good explanation + I have noticed that you have even a playlist about Fouries Series and other math topics. Thx from Germany!!
Thank you Dr Chris that's really helpful.
You have made it so easy! Big thanks ❤️
Still the best example after 9 years
Dr. Chris you are just amazing. I have tried understanding this topic on my own but I was unsuccessful. Your explanations and the ebook has made me grasp the concept here. Thanks so much and God richly bless you and grant you more success.
fuk off
Hi - the ideas are not restricted to only even functions. It works for general Fourier series.
you are so good at teaching this, its like you are teaching multiplication to a 3rd year math science student thats how clear and how well you explain it, thank you very very much for these videos! May i ask - what university do you lecture at? i am just curious
This gave me cold sweats, but I understand it a bit better now. Thank you so much 😎
i like they way you emphasise is good you even tell where a student may possible make mistake..thanks
Dr Chris Tisdell you are wonderful gifted professor who made a difficult course easy. Your students are luckier then me and many others who are wondering of youtube to find help.
Thank you. Hope that these videos have helped.
It really did. I made through the course with your videos. I believe without your videos I would have not been able to pass this class. Therefore, I can not appreciate you enough. Thank you a ton.
You just my semester sir. Thank you
Who are these 16 people who disliked the lecture they should leave the world.

you are awesomee !! Wish you were my proffessor at my university
Perfect Dr Chris
Excellently explained
This is great thanks mister I have learned a lot
Good luck with your exams, Jane (soon, yes?). Monash will have to wait, but you can always visit my classes on YT.
Awesome video. Thanks so much.
Love math and your accent!
Hi - could you please point to the specific time in the video regarding your question?
GREAT DOCTOR !
you just saved my life
My pleasure.
Wow nice sir.i can understand now.thnku sir.
Wonderful Dr. Tisdell. Come to Kenya.
I would love to!!
f(x)=x+pi, -pi
where do you work? I see every thing about maths in your brain. Thank you very much, my teacher
thank you very much!!! helped me a lot.
Great work. Thanks
Thank you.
I have an exam tomorrow so thank you so much
Thank you soooo much. Odds and evens, absorbed.
You are welcome!
@aqber OK, you got it now!
Welldone welldone Welldone Welldone Welldone..............you are great sir........
Thank you for this video..
Thanks, so much. UNSW, Sydney.
hey, you might not read this in time but;
i have what i would describe as an even function but shifted 10deg. im thinking of just substituting in x=t-10 or something to use the even simplifications. would this be an issue for later questions where i need to use the series to find the rms and THD using the first 5 harmonics. cheers
thanks make me happy to know this .... crazy .....thanks Dr.
:-)
@aqber Neither of the functions you list are odd. Can you see why?
Hero! I was so lost, i didn't understand my lecturer at all but this is gold man :') thanks
O can i just ask that if the questions asks for the first, say, 4 terms i just sub in n=1, n=2... and work out what the expression becomes?
You are welcome.
very helpful , thanks
THANK YOU VERY MUCH!!!!!!!!! MUCH RESPECT!
the last step is that, the odd extension function (fo(x)) does not satisfy the Fourier theorem. How do i conclude that?
great teacher
@DrChrisTisdell Since f(x) = x, is an odd function i assume f(x)= x+2 to be odd too. Is it conceptually wrong?
Thank you so much sir...........
You are welcome.
what kind of book did you use? thanks
i wish you are my clg professor
Thanks and feel free to visit me on YT anytime.
Great vid! :D Thanks a ton :)
Thanks.
thanks sir....very nice lecture & help me in make for presentation.....
good explaination
You're the best
X times cos is an odd function. For a(n) should the integral be 0? Around 22 minute mark
In the second last step, where did Cos 0 disappear?
why is x=0? it seems lucky that you chose that x=0 and it worked out. How do I know what value of x to use in a different question?
Besides that, THANK YOU VERY MUCH!!!
it easy if you releate odd to -1 and even to 1 (or just a negative and a positive number ) so odd*odd=(-1*-1)=even(positive) , odd*even=odd .. etc
Thanks Dr. now I just can’t believe this questions is going to be mcqs and there won’t be just one of them.
41:06 Dr, why X can be equal to +1 but not equal to -1 ?
loved it
thankyou very much
Yup, i realized both the function didn't satisfy f(-x) = -f(x). So both of them are not odd?
helpful thanks
how about to solve differential second order in simply way? i dont understand much in it.
thank you :)
thank u so much :)
plz upload lecture about dirichlet's condition
@47:45 why dont we consider both even and odd 'n'?
Isn't this function discontinues since there's no value for x=0?, f(o)=?
sir how to find the L in fuction whe he does'n gave in question..
what happens to a0 when its an odd function?
may god bless you
its easier if you just relate this part to the gate Xnor. let Odd = 0 , Even = 1.
There you have it. :)
sorry... can i get a new link, the old one is dead
thanks man
How I Calculate Fourier Function from a Curve ?????
Is ao value is 1/2L OR 1/L
I have the same question! Some textbooks say it's 1/L and then others say it's 1/2L. If you see this @Dr Chris Tisdell please help to clarify.
Many thanks in advance.
Thanks
please come teach at monash!!
Pls upload series' and sequence
THANK YOUUUUUUU
thank youuuuuuuuu
@DrChrisTisdell Thanks for ur immediate replies. Ur videos are great, i think if i had watched it properly i wouldn't have posted the questions. Thanks a lot....
Good vedio
i wish you could be in my universty should be okey
Thanks! :-)
thank you for saving my ass doctor
pleasw tell about fouriar serias functions having ponts of discuntinuty
