[2024/08/07] Hypocycloid
(lemmy.world)
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
tincreases the point on the inner circle should trace out the pattern, you can animate the graph usingt.
Below is the link to a Desmos graph:

[2024/08/04] Extended Euclid's Algorithm
(lemmy.world)
- Given
nandmare coprime, show that there exist integern'such thatnn' 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)

[2024/08/01] Multiple of modulus
(lemmy.world)
- 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
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
Hint:
spoiler
It is not a telescoping series
Solution:
that is simply genius
(i suppose it didnt come to me when i think of "irrational")
I love doing things the wrong way, so

holdup taking the side length of the unit square actually makes the working out a bit simpler, because the otherside is 1
idk i just saw the diagonal at first
2l+0.5 sqrt(2l^2)=1
l(2+0.5sqrt(2))=1
l=1/(2+0.5sqrt(2))
=(2-0.5sqrt(2))/3.5
=(4-sqrt(2))/7
also, all the public items on the drive is mean to be public, there are unlisted and private items u dont see
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
Revanced for youtube, someone even uploaded prepatched apks and ofc newpipe
infinity for reddit, its on fdroid
aliucord for discord, vencord for browser (rip opencord)
this is brilliant, as a londoner, im saving this
