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.

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:

  • 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

Hint

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


Hint 2

spoilerIt converges to -ln(2), but why

i main zathura, but okular is a good one as well

I've shown that ln(n/n-1) is always larger than 1/n, so Σln(n/n-1) for all natural number n will be larger than the series 1+1/2+1/3+...

but I don't know how to make sure the sum of all ln(p/p-1) only when p is prime is larger than the provided series

the question is strongly suggesting its divergent, i just dont know how to show it

i pulled the image from a meme channel, so i dont know if its real or not, but at the same time, this below does look like a legit response

i've been doing some 15 minutes of duolingo japanese for almost 10 months now, and i think i know a bit of japanese, and i could vaguely understand lyrics of songs if i stop it and read the text, i think the main issue for some people is that they only do it to "keep the streak", which is the case for a lot of my irl friends, and they barely learnt anything. One of my friend did do a large number of russian lessons daily, and i think he now knows quite a bit of russian (aka, can speak)

i dont think i'll be able to speak japanese in a daily convo in quite a while, cuz im too scared to speak, however im starting to understnad what they are speaking, so its not entirely accurate to say duolingo is pointless, cuz it really depend on ur attitude towards it

also, almost none of the anime kids ive met know any amount of japanese, the two topics couldnt be any more different

I expect my Arch desktop to get better day by day

I want minimal breaking for Debian on my Raspberry pi (I keep system apps up to date for security reasons, but I don't update mongoDB or TexLive when it just works)
