Yeah I can't lie, there is no calling this a daily challenge now.

Anyhow, have a go at proving this, I don't want any unrigorous "imagine zooming in until the line is straight" nonsense.

Difficulty: not a lot

Would appreciate if u put ur proofs or attempts below, I got a proof but it's like kinda mediocre.

I've seen some people talking about the reason this song being pop is that all albums must have a radio song where almost everyone in the general public would accept. So my personal take while this song diverges from the classic LP style and the 2 previous songs, it doesn't really count towards the theme of the upcoming album.

I hope this song is just a show of "we can do this style" rather than "we will be doikg this style from now on", because I can already name a handful of pop songs with a similar style, and it kinda loses the point of LP.

when i first heard it i thought it sounded like mainstream pop and didnt like it, but after hearing it a few more times, i starting to like it a lot, maybe not to the level of emptiness machine, still it good a cool rhythm and it vibes

proprietary, btw

 

all nostalgia aside, arras.io is so much better

Hint:

spoilerTry out the following tasks before going for the big one

  1. Draw a circle of radius a.
  2. Animate a point on circle a, let that be your rotational speed.
  3. Animate a circle rolling horizontally (along the x axis) at your rotational speed.
  4. Animate a point on that horizontally rolling circle.

You should now have an idea on how to draw a hypocycloid.

 

Draw a hypocycloid using a graphical calculator (such as Desmos or Geogebra).

Your hypocycloid should include

  • Inner circle of radius `a
  • Outer circle of radius `b
  • As time t increases the point on the inner circle should trace out the pattern, you can animate the graph using t.

Below is the link to a Desmos graph:

Hint

spoilerIf you are studying the algorithm, you are doing it wrong


Solution: https://gmtex.siri.sh/fs/1/School/Extra/Maths/Qotd%20solutions/2024-08-04_extended-euclid.html

spoiler

 
  • Given n and m are coprime, show that there exist integer n' such that nn' mod m=1.
  • The extended Euclid's algorithm is given below without proof, which may be useful in your proof.

(I'm too lazy to type out the algorithm again, so look at the image yourself)

  • Prove that z(x mod y) = (zx) mod (zy)

Be rigorous

(trust me bro im gonna daily post trust me bro)

EDIT: assume all variables are integers

because I have never heard of this argument before, ever. most media's stance on politics is "their party bad our party good", but the "all the parties are pretty hypocritical" argument has never been explored properly, because its depressing and nobody likes it.

yup thats the intended solution, im not really familiar with taylor series yet, but maybe for a person who knows taylor series would be able to see it right away

Hint

spoilerThe solution I have in mind is related to the Taylor series


Hint 2

spoilerIt converges to -ln(2), but why
