:antikappa:

Good.

Antikappa emote when

would it be a kappa but inverted colors?

yes

and facing the opposite direction maybe

See, that's way better than the shitty holloween kappa

you mean the one with the horns?

oh god

Oh look at that, it does have horns

i wasn't even talking about that one lmao

See, yours is more than good enough to sell for $5 in a lootbox

antiKappa 3 clicks in GIMP

Oh sorry, my bad

It's $64.40

that's disgusting

Amazon needs to make money somehow antiKappa

>gimp

i wish i knew how to use gimp well

i would use photoshop if my subscription didn't run out

i'd just use paint.net

i forget paint.net is a thing

I've been using photoshop so long paint.net is like a blur to me now

I fell for the "do everything in a browser" meme So I use https://pixlr.com/editor/

Where's your browser based video editor?

reggie became a cat

I just use the robust Youtube video editor Kappa

i should have used mspaint and just manually colored with inverted colors and a white background

Just freehand it next time, and scan it in

Not-so-rich art boi can do it definitely

not-so-rich non-art boi* antiKappa

mspaint is a professional tool

in browser video editor is wevideo

windows movie maker is also a professional tool

I prefer adobe premiere

The Real Mastermind

Holy fuck, that tutorial was more worthless than the fourier series one.

Russian dude I could not understand whos writting was unreadable. Good thing I already understand inner products and the Grahm-schmit procedure

The non mathphys people who did not take linalg 2 are fucked for quantum mechanics

why do you even need fourier series?

Waves

I assume

^

Until it turns out quantum particles were never waves to begin with

So, give or take 20 years

everything is a knot of quantum bands wrapped into 27 micro dimensions

Basically my phd thesis

Tbh

Pika, I'm not looking for a "real" explanation

But how is it that fourier series are used in so many god damn places

Idfk

Ask me when I am taught them

In 3 months

as a signal processing focus, i barely know what they are because we never use them

It's just weird to me, how that maths concept that we learned in HS is so integral to everything

I am expected to know them now, but not getting taught them until the end of calc 4

Leg, shouldn't that be all you learn in the signal processing world?

no i learned fourier TRANSFORMS

which are much more useful

We also need those

I mean, it's all related

All low frequency signals are essentially periodic after all

if i'm remembering correctly, the Fourier Series is a fourier transform but discretely sampled

Something like that

or is that the discrete fourier transform

Sounds not disimilar to what we did

Since we went from a sum to an integral

To get to transforms

Iirc

series are for periodic signal and transforms are for not, but you can just take the transfomr of the periodic signal anyway

At the end of the semester, they'll teach you how typing "fft" on a computer is 100x more efficient than everything you've done all semester

Doubt iy.

Calc 4 is not computers

i learned the math behind fft in my last signal class
