Is there a course similar as Khan Academy but for the Fourier transformation on the internet !

[joris.blanc]

So I'm starting to learn about the Fourier transformation in my math class and I would like to find a video course similar to the one that does the Khan Academy which is quite interesting and easy to follow to complete what I see in class.

Thanks

Joris

I remember reading something about them what are they used for again I forget. Gr or something?

 

[yuck]

i wish i could link you to my differential eq's course website, there was some good stuff on there. not video lectures but still pretty handy. you need an account from my university though. are there not khan academy videos for fourier? i can only suggest you keep googling, im sure theres stuff out there on youtube and whatnot.

actually i just found this in about 2 seconds. looks boring but maybe itll help

Try wolfram? I know I use it for fourier transform IR spectroscopy.

 

[yuck]

wolfram is also great if you dont mind reading it and sorta figuring things on your own

Patrickjmt might have some vids on it on youtube. Hes pretty much the exact same as khan and does a grwat job at explaining things

 

[joris.blanc]

Thanks man, I will look into that. His videos look quite interesting !

Thanks, I didn't know that Wolfram Alpha had some classes on their website.

dude.

fourier series was almost the death of me, but I got it down after a while.

You just gotta accept that it will take you hours and hours and hours to understand it. I just did practice problems like crazy and kind of wrote down the rules for when to use Fourier in all the temperature expansions and string contractions.

just make yourself charts of 'if and then'. like 'if the formula given is this, then' and give yourself a flowchart of when An and Bn exist and whether they are odd or even, etc.

I think i might have notes with me that I brought home, so if you are interested I could scan them up. But its like a one note sheet that I used to study for my final

Just finished a PDE's course on Fourier Series and Transforms. I learned (understand) more from this single page than I did in the whole course. I feel like most professors teach you to do the math, but not the theory behind it, and this does a good job with both.

its kind of weird, but none of that shit makes sense to me except for one of the animations.

I'm surprised. Probably change in name variables, and I noticed that nowhere included in there were y partials or odd/even functions..? Which I thought was one of the entire basises behind Fourier

this is what I used:

and a summary:

and if you need heat conduction or insulation or wave equations:

That would be so awesome, if you could do that for me.

I think my math sheet disappeared in the move back home (can;t find it in the math stack), but I'll look through my other stacks to see if it might have somehow popped up

:/

Sorry for the late response, I was in the mountains skiing.Thanks for all the links and everything you gave me, I'm finally getting to understand what all of this is all about

Kahn Academy is the only reason I passed organic chemistry.
