So Israel military is attacking the UN peacekeepers now (update: read comment)
  • siriusmart siriusmart 6d ago 100%

    That would maybe make sense.

    Yeah I think the claim might be true, but still there are probably ways to not hit a UN base of fixed location while carrying out an offensive.

    This detail wasn't here this morning, the article is gradually edited as more info surfaced. See the url for the original title.

    [2024/08/07] Hypocycloid
  • siriusmart siriusmart 2mo ago 100%

    Hint: ::: spoiler spoiler Try 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. :::

    1
  • 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: https://www.desmos.com/calculator/vzgog7xqrz

    [2024/08/04] Extended Euclid's Algorithm
  • siriusmart siriusmart 3mo ago 100%

    Hint ::: spoiler spoiler If you are studying the algorithm, you are doing it wrong :::

  • - 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)

    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.

  • I'm a Londoner, I used to have this friend (who is *not* a Londoner) we had a huge disagreement on topic unspecified. But after I've watched this video I think I see his viewpoint, which is true. I just don't see it at all because there's such a enormous disconnect between London and the rest of the country. I would recommend you to watch the video as well, some arguments made in the video are slightly misleading, but the general picture is clear and true. https://youtu.be/b5aJ-57_YsQ

  • Infinite product follow-up
  • siriusmart siriusmart 5mo ago 100%

    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
