Crazy product rule proof

In this video, I give a neat proof of the product rule by using the Fourier transform. It’s really neat and natural! Enjoy!

Should've gone all out and used Laplace using s with real part equal to 0

11:45 unimaginable words that we can think coming from an KZbinr's mouth, "To quit this video", after getting all the info. of ur concern. Most KZbinrs of e-learning channels are mean(Readers don't mind it, only for those means), always thinking of maximizing the watch-time & views for their videos by sying that usual irritating sentence, "Watch this video till the end". But, the words of this guy has literally touched the heart. This really shows that he's a true TEACHER, always thinking of his students welfare first and with a sweet smile on the face, while teaching :-) God bless U. Will now surely recommend ur channel to my Mathoholic mates. GR8 RESPECT & SALUTE TO DR. πm & all such E-teachers like him.

As always...fantastic. Thanks.

Green shirt for the win. Real smooth.

Thanks for u D peyam السلام عليكم

11:28 You say that you can only apply the fourier transform to infinitely differentiable functions that rapidly decay to 0? I thought the fourier transform was defined for all L^1/L^2 functions?

Très agréable!

i beleive dr peyam sleeps with a blue pyjama recovered by yellow stars

[@drpeyam]

Close! Blue pajamas with black birds. How did you guess?

Title didn’t lie, that’s insane

The second part of the video looks like just proving an integration by parts through the limit definition of derivative in a specific Fourier integral. It seems to me that this proof might be done in general case

[@drpeyam]

Interesting!

[@virat.chauhan]

Thanks for watching.....sir😂

[@tracyh5751]

I was watching this video without sound and thought that the xi was a 3 for a really long time. I was wondering why you were going through the video with such a specific example until I realized my mistake. :p

[@drpeyam]

Hahahaha

[@allyourcode]

Yes, me too.

@@drpeyam Not really because a lot of times people like the video before watching it.

second!

[@Vincentsgm]

u should have worn an hat for this video

[@drpeyam]

Hahahahaha, OMG, I should have!!!
