If you have any questions, please ask. I love yapping.

Let's say we have some periodic function f. The goal is to represent it as a bunch of sine waves. This is called a Fourier series (FS).
The FS coefficients are given by
⌠2⋅π
1 ⎮ -i⋅k⋅x
f̂(k) = ─── ⎮ f(x)⋅e dx
2⋅π ⌡0
for whole numbers k. We can then approximate the original function with
n
___
╲ -i⋅k⋅x
╱ f̂(k)⋅e
‾‾‾
k = -n
and make the approximation better by making n larger.
For non-periodic functions, we can still get an approximation! The Fourier Transform (FT) uses a continuous range of frequencies instead of whole numbers, and the sum is replaced by an integral (the inverse FT).
FT's are used everywhere, for example in signal processing and spectroscopy. If a recording contains an annoying high-pitched noise, we can apply the FT and filter the unwanted frequencies. Spectroscopy separates light into its different wavelengths. By comparing the resulting spectral lines with known measurements, we can determine which elements and molecules are present in stars and planets, for example.
idk what more to add ._.

As a reminder, please do not discuss current struggle sessions in the mega. We want this to be a little oasis for all of us and the best way to do that is not to feed into existing conflict on the site.
Also, be sure to properly give content warnings and put sensitive subjects behind proper spoiler tags. It's for the mental health of not just your comrades, but yourself as well.

Is it tacky to give this person I'm going out with a drawing of her in the lying venus pose? Fully clothed because I don't have that intimacy, but I really just want to draw them
I said this but I was already starting the drawing. I'm done with sketching rn. Will start actually drawing later
Sounds gay I say do it
Its very cute, but I will say I could never display a picture of myself in my home
It is. The real question though is "Is that a bad thing?"
Great point, I don't think they will find it bad
I would melt if someone did this for me
