Complex Fourier Series Example Problem! (part 2)

There is another version of Fourier Series: the complex form! In part 2, we apply our complex Fourier Series to a simple example problem (the same one we did in the sine and cosine Fourier Series!).

CORRECTION: @ ~ 3:00 the cosine formula should NOT have an i in the denominator (since it's the real part, not the imaginary part): cos(nx) = (1/2)*(e^(inx) + e^(-inx))

Questions about this or other math topics?? Leave a comment and let's tackle it together!

You saved!! you can make complicated topics simple!!! I love you!!!

[juniorcyans]

Gosh! I need this! Super cool! Smart! Thank you very much!

Watching your videos from France (north of Lyon). Your are cristal clear, thank Jen you for sharing and sorry foor the loss of your best friend Jean Pierre Dorte

Thank you so much for this example! This was a great explanation. I just learned the derivation of the complex Fourier series and this video helped to solidify that knowledge.

Great, this stuff helped me a lot ...So I wish you all the best to bring more videos like this .
Thank You

Amazing, this chapter for me is now a self study due to the pandemic and I have an online exam next week, just subbed & you are amazing

Again amazing approach 😍 👏 and for me happy remembering.

Great Video. I really love it. It was so difficult for me to understand but the explanation is amazing. Just one thing which i dont understand in this video in the step 2 around 3:35 sec time. why you are writing -1/in with 1/2pi.
thanks

[geogaddi]

Thanks for the video. I would appreciate it if you'd do a transformation one in the future.

Differential equations plse u r superb tutor

[engineersupervisor]

Thanks a lot teacher .really it was very helpful

[canadian_blue]

Top shelf ... got this final in 30 mins

[icandothisallday]

Seems like so many things to memorize in this exam, better to use (sine + cosine) or better to use complex? How do I decide when I first look at the question?

[hymavathi]

Can you teach me on how logarithm tables were created? Trick?

[danialkhan]

really helpful could not figure out this shit on my own

[mtopangaprimo]

The COS (-npi) I read and understood that its gonna be +ve cos.looks like i missed something somewhere.Could you please help me understand where my mistake is.Thanks for the great videos by the way.I appreciate it Mega.

whwre is the negative on the first exponent for ix

[s.mathankumar]

Hai I am mathan If you tech any 1 problem in complex from of Fourier serious

[blaxemusic]

will u like marry me ??? thank u so much for the support.


small pointer : would prefer a white board, will make it more clear
