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.

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


Solution:

S=sum of (-1)^n/n from 1 to infty

For why I named the post as so, here's why

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

Here's a rly cool solution from stackexchange, which blows my average geometric solution out of the water

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

  • Show that cosθ=(u⋅v)/(|u||v|) for 2D vectors u and v.

(it is quite hard to come up with these challenges, so if you got any ideas, please post them)

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

the background it likely ai generated anyways

(i took the meme off some discord channel, so i dont know how its made)

Solution (starter question):

Please refer to the main post, if you don't like looking at the image. https://gmtex.siri.sh/fs/1/School/Extra/Maths/Unsolved/1d-gravity.html


For the main question, you are encouraged to share your progress

spoiler

You might be able to solve this with differential equations, or by solving the iterative functions, I dont know

I've even got a starter question to get you guys into the scenario.

Once you've completed the starter question, under the solution comment attaches the main question, which is unsolved.
